Are you going on gut feel? Or off minor league track record? Personally, DeRosa strikes me as being equally likely of being exposed. I'm with Tim, I think both are similarly vulnerable to the "exposure" factor. And I don't care about the contracts. If anything, that DeRosa has more experience playing everywhere (including RF for possible Jacque platoon) makes him a better utility candidate, if in fact they were interchangeable at 2B. I'm not sure how to grade them defensively. Part of me thinks Theriot could be better, but I'm not confident. I think Theriot has a chance to be significantly better in terms of OBP. DeRosa K's a lot, which doesn't favor his batting average. I think Derosa has a chance to be significantly better in terms of OPS and slugging. He hit teens HR's last year and lots of doubles, IsoP. Theriot has always been a strictly singles guy, other than his tiny sample with the Cubs. To some degree, I think DeRosa might be exposed by regular playing time as much or more than Theriot. DeRosa has had strong lefty-righty splits. So I'm guessing that his past playing time has been stacked to his strength, versus LHP. If he's facing RHP day after day, that could really hurt. Theriot also has R/L splits, I think, but I don't think as extreme. And since he has negligible power either way, less likely to be as severe. I think OBP is the only offensive category that Theriot could have an edge in. DeRosa's .SLG and .OPS should outweigh the OBP advantage though. I could be wrong though... 8-)
