My pal Matthew Leach has sent up a WhatIf league that has some open slots. It's not free, but hey, getting a chance to beat me and some other baseball types shouldn't be free. Here's ML's pitch:

"It's not quite fantasy, it's not quite Diamond Mind or
Scoresheet, but it is fun. Build your own team within
an $80 million salary cap, made up exclusively of 2004
players, and then do battle in simulated games with
other owners/GMs/managers. "Live" simulations can be
set up if you prefer. Join baseball league 39952 at
WhatifSports.com."

I've also accepted an invite to take another shot at Sportsline's Expert League. In my case, the term "expert" is used loosely, but I did come in third last year. I'll be looking for help. (BP's also taking part in LABR and, I think, Tout Wars.)
