There are openings in the MLB sim league on Total Sports Heaven (
http://www.totalsportsheaven.com). Since the league is just being re-started, most of the teams are available. The taken teams are listed at the bottom of this post. The sim runs using Baseball Mogul 2010 (the league file has been updated to reflect all offseason moves up to February - so Halladay is a Phillie, Granderson and Vazquez are Yankees, Lee is a Mariner, etc). You can still play if you don't have the game...actually, the game can be provided. I was actually recruited to join the sim from here, so there's a bit of irony. You will have to sign up to TSH to take part in the league, but the site is fun as well. We talk about all things sports-related, and quite a few things not sports-related. Anyway, there's the sales pitch. Thanks in advance for your consideration.
Teams taken as of this posting: Yankees, Red Sox, Rays, Rangers, Brewers
