TBL Day at the Colorado Rockies, Friday, May 10, 2019
by posted 02/11/2019


Hello Thunder Baseball Families!

Please save the date, Friday, May 10th.  This is Thunder Baseball League Day with the Colorado Rockies at Coors Field.  On top of the celebration and honoring of Thunder Baseball, the Rockies will be taking on the San Diego Padres in a divisional show down.  

For those of you who are new to Thunder or maybe didn't get to attend last season, I want to share a few details.  All Thunder Baseball players who attend Thunder Baseball League Day at Coors Field will get to participate in a parade around the warning track during a special pre-game ceremony and then sit with their team to watch the game.  It is an incredible experience for the kids that they will never forget!

More details will come out in the next few weeks and I will be coordinating everything with your coaches.  However, I wanted to give you the opportunity to put this on your calendars ASAP as this is an event for the whole family that you will not want to miss.

Thank you and I look forward to seeing you at Coors Field on Friday, May 10th!

Parking and drop off suggestions
by posted 01/12/2019

No Parking


Thunder Families,

Welcome to pre-season workouts. Thunder teams enjoy the benefits of extra repetition during Jan-March, in order to keep our competitive advantage over other baseball associations.

However, this is the busiest time of year at Thunder Academy's indoor training facility. We have limited parking spaces in designated areas on the street, north of the building and south of the building. There are even some limited spots on the west side of the building.  

Although most businesses are closed during our training time in the evenings, we still need to respect the posted signs and markings on the parking lots.

We understand the Broomfield police may have issued some tickets this past week, so in order to ensure no more tickets are issued, please obey any posted signs. If you are able to carpool with other players on your team, this would help alleviate the congestion. Be respectful of other cars dropping off players and keep the traffic flowing.

Thank you for choosing Thunder Baseball League.

Machine Pitch Baseball Information
by posted 01/08/2019

Machine Pitch

Thunder Families,

Do you know of any 6-8 year olds looking to play the next level above recreational baseball? We are forming teams now and registration is open. This a great place for youth boy's and girl's to get exposed to a more developmental experience than Tee Ball or Coach Pitch Baseball. See the link below:

https://2019 Machine Pitch Flyer.pdf

Highlights to the program are:

  • Featuring Jugs single wheel pitching machines
  • Predictable game schedule on Saturdays
  • Ages 6-8 years of age
  • Previous recreational baseball experience preferred
  • Home games at Broomfield Industrial Park (BIP)
  • “Opening Day” is April 6, 2019
  • 8-10 games with an “End of Season” Tournament
  • Teams formed late February
  • Team meetings in early March
  • Indoor practice at Thunder Academy 1 day a week starting in March
  • Registration fee $275 includes team A4 jersey


One big advantage with a pitching machine consistency. The use of a pitching machine is a great tool that allows young hitters to get comfortable being in the batter’s box, without the fear factor of being hit by the ball.

At a young age, or any player just starting out, the most important batting skill that you will want to concentrate on is the mechanics of the swing. The ability to have consistent strikes thrown to the batter allows you, or the coach, to concentrate more on teaching the mechanics.

By removing the fear of being hit, and giving the batter the opportunity to swing at consistent strikes, you will quickly and easily build confidence. Building confidence in a beginner is very important.

Umpire Training Class
by posted 12/20/2018


Thunder Families,


Looking for some extra income? Want to spend more time with your 14+ year old son or daughter? Do you want to make a difference in your communities youth baseball program? Have a desire to know the rules of the game of baseball? Are you a coach or parent that wants to learn a different perspective of the game? Then continue reading below.


My name is Nick Prosser, and I am one of the assigners for Mile High Umpires LLC.  We are an organization that runs 23 tournaments a year, spring and summer league games for RMJBL, and fall baseball for a bunch of the areas within the Denver Metro area.  We are excited for our upcoming umpire class and hope that you will be in attendance. Payment will take place prior to the first class beginning.  See rates below.  PayPal or Venmo will be accepted for payment. Depending which payment route you choose, the proper information will be given to you, so please let me know and I will get you the information you need for payment.  Now, on to the information you'll need to succeed in this class.


Attendance is required, but we are flexible.  We understand that people have lives outside of this.  If you need to miss a class, please inform us ahead of time so that we can prepare materials for you to get caught up.  We are planning on running this class as fast as we can to get everyone on the field and making money.  As of now, our dates consist of Wednesday evenings beginning on January 16th, and Saturday sessions finishing up on February 22nd. Afull schedule is listed below.  Please come dressed to be active.


The two guys training this class are both former professional umpires that worked games in minor league baseball.  They are two of the best umpires from the state of Colorado and are great instructors as well. There will be a multiple-choice exam at the end of our rules sessions.  This test usually spans from 50-100 questions. We want to set you up to succeed in this business. We are resources that you will have at your disposal throughout your umpiring career. Whether this is a summer job for you, part time, or if you wish to go to pro school, we can push you in the right direction. We will be giving away free gear and other items that will be used on the field during this class.  We like to have some competition and a little bit of fun to break up the monotony of classes.  Please on Wednesdays come prepared with a pen or pencil.  Rule books will be provided.  I have a full set of plate equipment to give away, as well as some plate brushes, indicators and things like that.  We will also discuss the assigning process in depth as well as how you get paid for games.  Starting pay is $40 per game, games are an hour and 45 minutes long, so over $20 an hour for a starting job and you get to watch baseball while doing it!  Once the class is completed, you will only be required to show up to a veterans meeting in the winter each season.   Students must be 14 years or older to work baseball games.


Classes Cost $120 per student if registered and paid before January 5th.  After January 5th, classes are $150 per student.

11 important ways!
by posted 12/07/2018



Thunder families,

Youth baseball parents have a difficult job. On top of making sure your child is dressed, fed and prepared, you get to sit in the stands while all of the pressure rests on your player.

However, there are several things that you can do that will not only help your child, but help your coach and the team. A team of parents who fulfill these 11 roles is most likely to have a drama-free season!

11 important ways that youth baseball parents can support their child, team and coach.

1. Volunteer

Volunteering is the first and most obvious way you can help your coach. It’s the most visible way you can contribute to the team.

Assistant Coach: Do you have experience as a baseball player or coach? If you have a desire to teach, this is a great option. But the motivation must be for you to help the entire team, not just your child.

This is something to consider for the experienced baseball parent. Instead of complaining on the sidelines, be part of the solution!

Scorekeeping: Your coach may need two or three scorekeepers. Some teams choose to have both a pencil and paper scorekeeper as well as a parent who manages the scoring virtually like with Gamechanger or iScore. Some teams may even need a parent keeping track of innings or pitches.

Some teams experiment with a defensive scorekeeper this season — that’s going to require yet another volunteer!

Fundraising: Travel baseball is expensive. Most teams have some sort of fundraising or process to recruit sponsors to help with the costs.

Of course, doing these things well requires some skill. A good fundraiser is an organizer and networker. If that’s you, let your coach know!

Team Manager and Culture Keeper: Maybe the most important role. Your coach needs someone who is a liaison between the parents and coach. This person is the buffer for complaints and helps with communication.

Additionally, a team parent is often the one who collects paperwork and makes sure everyone is paid up and eligible. These are responsibilities that, if taken on by the head coach, can add significant stress and distraction.

2. Provide Healthy, Timely Meals

Don’t be that parent who doesn’t feed your child prior to a game. And don’t be that parent who sends your child to the dugout with a bag of fast food prior to warmups.

We know that home cooked meals are a challenge during baseball season. However, it doesn’t need to be a gourmet meal. Your child needs fruits, vegetables, protein and water to supply the energy needed to get through a day of games.

Please, no fries. No soda. No candy.

Timeliness is important, too. A meal shouldn’t be consumed on the way to the game. Have something ready in between games, too!

3. Enforce a Curfew

Traveling is one of the fun experiences of tournament ball. However, it’s easy to fall into the trap of staying up too late prior to morning games.

Your coach has plenty to worry about. He doesn’t need to add tired kids to his list of concerns.

Understand the schedule, and establish a reasonable curfew for your child even if your coach does not.

4. Be Dependable

It’s not expected that you’ll make every practice. And exceptions can even be made for missing the occasional game. But please… Please be dependable.

Make attending practices — on time — a priority. Make getting to games — on time — a priority.

In fact, you can relieve a lot of coaching stress by not only arriving on time, but by getting there 10 or 15 minutes early.

Of course, you may have conflicts. But when you know of these conflicts, you need to tell your coach ahead of time so that he knows — and remind him a week and a few days ahead of time!

5. Stay Away From the Dugout!

This is a pet peeve of ours, and we think we speak for most coaches. When the game begins, let your child be.

We know this is tough. It’s tough for us, too, when we are attending our kids’ games as a spectator. And we admit that we occasionally violate this rule.

But this can be a major problem. You think you are helping, but it often isn’t the case.

Your child just made an error in the field. Or he did something wrong that you think needs to be corrected. Resist the urge and stay away.

Ultimately, your coach or his assistants are the ones who need to talk to your child during the game. They may have already, and you didn’t see it. But your involvement often makes things worse.

Your child wants to please you. Your presence at the dugout only reinforces that they messed up. This often leads to tears and more emotion than was there prior to you being at the dugout.

Additionally, your advice may not be consistent with what the coach is telling your child. So while you think you know the perfect thing to say in that situation, your encouragement may just cause more confusion.

6. Reinforce the Message

Understand the coach’s philosophy. Know the approach and strategies that he teaches. And support that approach.

Let’s say that your son swung at the first pitch late in a game when he was given the take sign. Support your coach by explaining that approach and why your child should follow it. Don’t completely oppose your coach by saying that he was right to swing in that situation.

You need to be an extension of your coach. Even in cases where you disagree, it’s important that the kids buy into the system. Conflicting messages only makes things more difficult.

Treat your player to ice cream, frozen yogurt, or even a frozen slurpee after a game. Avoid the temptation to discuss the baseball game in the car ride home. The best thing to say is "I love to watch you play". Players need to know you are sharing the experience good or bad.

7. Remain Positive

When the team is struggling, remain positive. Cheer louder. Encourage the players. Remain positive about the team when talking to your child.

Just as importantly, remain positive when your child is struggling. Don’t yell at them during a game after they make a mistake. Talk constructively with them about their struggles after the game.

These kids will be kids. They can be delicate emotionally. Your coach needs you to remain positive to keep them positive since the mental side of the game is so important.


It’s exciting when your child makes a big play. It always means a little bit more when it’s your child who is in the spotlight. But there are 10 other kids out there. Cheer them on!

This is where it becomes a baseball family. Don’t be on an island, only supporting your own child. And if players other than your child make mistakes, encourage them, too.

Treat these kids the way you want the other parents treating your own.

You may get frustrated with other players on the team. Avoid talking negatively about them in front of your child as they are bound to take that with them.

9. Show Appreciation

We don’t want to be a martyr here, but being a coach is hard. It’s stressful. It’s rare that everyone is happy. We don’t get paid. We lose sleep and our health can suffer. 

Appreciate the sacrifices your coach makes!

Oftentimes parents will get together to get the coach or coaches a gift at the end of the season. That’s awesome and appreciated. But keep them in mind during the season, too.

No, that doesn’t mean you need to keep giving them gifts. Just appreciate all that they are going through. Reflect that in the way you talk to and about your coach.

10. Avoid the Drama

It’s funny. When a team is playing well, everything is right with the world. But as soon as things start going downhill for a youth baseball team, watch out!

Fingers are pointed. People start complaining. Arguments begin.

Don’t be part of this madness. It’s not helping. And really, it’s this drama that creates the cracks that inevitably lead to a team imploding.

11. Communicate Well

You won’t always agree with your coach. But when that happens, know how to handle it.

Don’t yell at a coach during a game. Don’t walk through the dugout and onto the field to ask why your son is on the bench. Don’t send a series of long emails at midnight after a game.

Yes, you might imagine that we’ve experienced all of these things. But our experiences are not unique. As great as the families have been during my years of coaching, these things happen to all coaches.

Don’t ever talk to a coach during a game about your child’s playing time. Seriously. Please, avoid this at all costs. You won’t get what you want, and in fact you may just get the opposite.

When emotions are high, emails are also a bad idea. It’s far too easy for tone and intentions to be miscommunicated. Emotional emails almost always make things worse.

Follow a 24-hour cool-down period. If you’re upset, don’t talk to the coach after the game. Think about it for the next 24 hours. You may even realize that whatever was bothering you isn’t a big deal after all.

If you still need to talk, set up a time to chat face-to-face with the coach. Do so calmly. Don’t be combative or confrontational. Again, understand the complexities that go with coaching and trying to keep everyone happy.

MLB Pitch,Hit,& Run and TBL Picture Day at BIP on April 22, 2019
by posted 08/15/2018

MLB PitchHit&Run

2019 MLB PitchHit&Run Rules*

Thunder Baseball League (TBL) is proud to be offering MLB Pitch Hit & Run for boy's and girl's in 2019. See for more details.

This event is open to all Thunder Baseball or Thunder Softball members.  Players age will be determined by age as of July 17, 2019.  MLB Pitch Hit & Run Local edition is scheduled to coincide with TBL Picture day on April 22, 2019 at Broomfield Industrial Park (BIP). 

Each team will be assigned a time by TBL for pictures by Champ Photography.  Picture times will be sent to team managers and posted on the TBL website the second week of April. Picture packets will be available the day of pictures and you can visit for more information.  After completion of team pictures, players interested in participating in the MLB Pitch Hit &Run event should head over to the registration desk.

All participants must have their parent or guardian fill out a registration/waiver form at check-in.  Boys and girls, ages 7-14 will be grouped into 7-8, 9-10, 11-12, and 13-14 with boys and girls competing SEPARATELY.  (No metal spikes are allowed).

All parents and spectators should remain off the field at all times. This program is free of charge, in an exciting baseball/softball skills competition in the safest atmosphere possible.  Pitch Hit & Run is intended to encourage youth participation and emphasize the “FUN” element of baseball/softball. 

PITCH-Each competitor receives six (6) attempts to hit the designated “Strike Zone” from 45 feet away for boys and 35 feet for girls.  Competitors must start from the pitching rubber and deliver to strike zone target which is (17” x 30”) measured 20 inches from the ground.  Each attempt hitting ANY portion of the “Strike Zone” target is worth 75 points.

HIT-Each competitor receives three (3) swings in an attempt to hit the ball off a tee.  Only the best of the three attempts, as determined by the administrator will count toward a competitors score.  A swing and a miss count as one attempt.  A running start is not permitted.  A competitor that fails to hit will get a minimum score of 50 points.  Spotters A & B stand on opposite sides of a tape measure, holding several flags/bean bags to mark the initial landing of the batted balls.  Spotter A calculates the inaccuracy of the hit and the distance traveled.  Distance traveled but the ball lands ten (10) feet to the left of the measuring tape.  The score would be 130-10 =120 feet.  The conversion table would be referenced and convert to 120 feet to 240 points.

RUN-Each competitor will start at second base from a standing start, and begin running when the admin yells GO!  The runner will be timed from the moment he/she leaves second base, touches anchored third base, and touches home plate.  No sliding is allowed.  Total distance for boys is 160 feet and the girls 120 feet.  Standard distance between bases in the boys division is 80 feet and the girls is 60 feet.  Times to the nearest 1/100 will be converted to points.  Example: A competitors 9.50 second time equals 100 points.

*Administration reserves the right to modify the program at any time.
