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.
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!
I have been on this site for a few years now. There is truly nothing like it. Nothing remotely compares to this site. The community is phenomenal. The site is run extremely smoothly and well. Best site for avid baseball lovers.
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.
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.

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! How could anyone not love it?
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!
A friend of mine invited me, and my first thought was, "This is gonna be boring!" Well, I'm hooked! I find myself counting down the clock as the next game gets closer. If you like baseball, and you're looking for a good sim, this is it!

  • Automate player aging and retiring between season
  • Create team budgets and player contracts
Most importantly, the site is simple and easy to use. The simulations are based off real, tangible stats – not arbitrary ratings. And the stats are basic so that the sim results make sense. We’re not going waste our time with nonsense like, “How well does a batter hit on turf during the day against lefties?” If you’re looking for that level of stat geekiness, you won’t find it here. The philosophy is to keep it simple and fun. Obviously, the more time you invest, the better you will become at building a winning team. But you don’t necessarily have to spend hours and hours to be successful. And remember, it's about having some fun. In the end, plenty of "luck" is involved, so don't take it too seriously!


Admittedly, there are some limitations, and the biggest one right now is that this site only supports the DH. As you can imagine, there is a lot of complex logic involved in extending the simulator to support pitcher batting, and if I don’t have time to do it right, I don’t want to do it. The game is still fun and rewarding, even if you aren’t a huge fan of the DH. But this is something I hope to add in the future.
