The 2021 American Division Champion Mets

The 2021 American Division Champion Mets

Revenge game for the Championship

Just as was the previous year, the Mets and Rangers squared off again for the Over 50 Championship, but this time, the Mets hung on to take the victory.  By playing an excellent defensive game, along with great pitching and timely hitting, the Mets were able to hold off a late game rally by the underdog Rangers and win 6-3 for their second championship in three years.  The game also marked manager Nelson Rodriguez’s last game as he has officially retired, ending his Over 50 career on top.

A fellow Denver NABA baseball player’s family has experienced an awful life changing event.  The family's house, located in Wisconsin, has burned to the ground.  Thankfully, no human life was lost.  Apparently there is no insurance and the family is in need of assistance.

I thought you might be interested in supporting this GoFundMe,

Even a small donation could help Bruce Brue reach their fundraising goal. And if you can't make a donation, it would be great if you could share the fundraiser to help spread the word. 

Thanks for taking a look!

The 2020 National Division Champion Spikes

Early season struggles pay off with Championship

The Spikes, who overcame a 1-5 start of the season, rallied twice against the Fossils to ultimately win 12-9 and win the National Division Championship.  As they did to turn around their season, in a true team effort, the Spikes had a big rally in the 7th inning to put the game away for good and take the win for their first championship since 2017.

COLORADO OVER 50 BASEBALL, INC (A not-for profit corporation)

We're one of the nation's largest independent baseball leagues for both "semi-experienced and experienced" players. We have both men and women players in our league.  Men must be at least 47 years of age at game time while women can play if they're at least 21 years age at game time.  We schedule nine inning games with a limited stealing rule and liberal substitution to ensure that all players get the maximum benefit and enjoyment while playing baseball in our league.

If you played baseball (not softball) “a long time ago” know that our league has many players just like you. If you played only softball, you can still have fun and be competitive in the games we play. It will take a little more practice to get you up to speed.

• Time Commitment: Minimum you can count on is 3 1/2 hours each week (Arrive early, and play 2:45-3:00 hours each game). Some teams schedule weekly practices, some don’t, so that is up to the team you are selected by. You can go to our website at and click on the link for field locations so you can also figure travel time.  Games are on Saturday or Sunday at 9, 12:15 and 3:30 PM.  Depending on your team, you may have an equal number of games on each day or one may be a majority. 

• MONEY: You should expect it to cost between $270-$295 for your league fees (15 game minimum) depending on your team’s roster size. You might also spend up to $100 on uniforms and $50-150 on “lumber”. Lots of help is available in these areas. Of course, you will need your own equipment (gloves, rubber/moulded plastic spikes, helmet etc) so be prepared to spend happy moments and $$ in your local or online sporting goods store.
