San Francisco Giants issues I've found-
AAA 1B Jesus Guzman is listed as a switch hitter, when he is actually a right-handed hitter in real life. He has been inaccurately listed as a switch hitter on some websites (either that or he used to switch hit, but he doesn't anymore), but here's his Giants page:
Jesus Guzman Stats, Bio, Photos, Highlights | SFGiants.com: Team
His City of Birth is also listed as "Barinas" in-game, but this page says he was born in "Sucre, Venezuela".
Also, don't know if the lineups and pitching rotations matter to you guys, but if so... Matt Cain and Randy Johnson should be swapped in the pitching rotation (make Cain #3 and RJ #2) and Barry Zito and Jonathan Sanchez should also be swapped (make Zito #4 and Sanchez #5). That is the order they've been pitching in all season.
Eugenio Velez is listed as starting at 2B and leading off in all four lineups. He should be a bench player, and Emmanuel Burriss should be the 2B starter, as he has been all season in real life (and Velez has been sent down).
The actual Giants opening day lineup looked like this:
RF Winn
SS Renteria
LF Lewis
C Molina
3B Sandoval
CF Rowand
1B Ishikawa (Aurilia against lefties)
2B Burriss
They have changed some things around over the course of the season, but that is what it should begin at if you want real opening day lineups.
Also, there are a lot of minor leaguers who are at the wrong levels. For example, Madison Bumgarner starts at AAA, but in real life he opened the season at High A. I can make a list of the rest of the misplaced players, if that's something that would help. Let me know.
