Sorry to hawk someone else's site, but has anyone checked out the new BaseballReference.com site? Some of the new features are pretty friggin great. You want to know Mora's stats between 2002 and 2005? Just click on those years and it'll sum it up for you (including league adjusted stats). You can generate all stats in CSV format, so you can load them up in Excel. They also sum up stats automatically per team a player played for. And they finally added some advanced fielding stats (which was probably their biggest weakness), but still no VORP or WARP that I can find (although they do have batting wins and batting runs).
There seems to be a ton of changes and a ton of new stats.
