Free Online Baseball Sim Leagues

Welcome to, where the philosophy is to offer easy, accessible, fun and free baseball simulation. This isn’t fantasy baseball, but fans of fantasy baseball will surely dig it. Be the baseball manager of your own team in this great online baseball sim game!

  1. Sign up and join an available league
  2. Pick your team's players (no salary cap restrictions and no duplicate players on multiple teams!)
  3. Wait for the league to fill and let the games begin.
  4. Juggle your roster, make trades, manage your squad as you fight for a title
  5. Play in a variety of leagues featuring every era of baseball history.

Truly dedicated users can even run a private league using simple and powerful commissioner tools. The developer of this site has over a decade experience running his league online, inspired by the great PC simulators of the past like MicroLeague and Earl Weaver.

If you’ve paid to play in other online leagues, you’ll be amazed at what is offered here for free. Obviously, we can’t possibly offer everything the big corporate sites can, but we come pretty close, and actually exceed the competition in some areas. So jump in!

This is by far the best fantasy baseball site I've ever been to. It took me weeks to find a good one. When I found pennantchase, I was hooked immediately. I would definitely recommend this site to any baseball lover. - gr33nappleboy

I know it must take a whole lot of time to put this together and keep it updated. Really is awesome and the fact that it is free is beyond comprehension. Thanks for making one soul happy for a few minutes each day! - biggcommish

This is probably the best baseball sim site that I have seen. It is more user friendly & allows more user interaction than SIMDYNASTY or CSFBL. I congratulate you, sir. -nsj16

This really is the league that my friends and I would discuss as we played ball all summer long! All the heroes of the '80s, unbelievable! Thank you so much for all your hard work in putting this together and keeping it running! This is SO much better than fantasy baseball! The memories it brings back are priceless! - gashousegang34

Thanks man, you've got a great site here. It gives my father and I another thing to enjoy together. Very cool of you to offer it up for free. - smittyjones

Love the site very much!! You have created a daily habit that takes me away for an hour or so, from the business and worries of life!! Keep up the great work!! - ranger

This is one of the best sites I play on. I play in plenty of leagues, and despite being fun, its nearly impossible to keep the owners active. I also admire the fact that this is run by one person. Keep up the great work!!! -soriano261

I think you did a great job on this website... thanks for a great online baseball game. -bones13

I think this site is great and very simple to use. I like the setup. Also, I don't have to change pitchers constantly like many other sites. -rgilman57

Great site. This is truly the best simulation baseball site on the web, ever. Continue the good work and hopefully the site keeps on rolling. - wyldman95

I have played on numerous fantasy baseball sites - MLB, CBS, ESPN, pretty much any site on the web... and this is the best BY FAR. If you want to play with your favorite players, this site is head and shoulders ahead of the others, no competition! - SoxKidFan1

This is my favorite website. Wow, what a great job you have done. This site has a great community and it is the best, most realistic online baseball simulation game out there. Plus I'm thankful it's free! - habsco
