You have to take a lot in account in the Cedeno v. Theriot argument. On one hand, you have a 27-yo college experienced guy, on the other there's a 24-yo raw player. Theriot hasn't hit well recently and has a low .600s OPS since the 3rd week of the season. Ironically, very similar to what Cedeno did last year. There's a much better chance that Ronny improves than Theriot, simply because age and talent are on his side. Defensively, there's no signs to point to Cedeno ever being as bad as he was last year. Theriot is definitely more sure handed of the two, but range and arm go decidedly in Cedeno's favor. That being said, if Izturis is still gonna get the ABs at SS, then Theriot is the better option to start occassionally and pinch hit. But once the Cubs decide the Izturis experiment is over, then Cedeno should be handed the SS job. I guess. However it depends on what your objectives are right now. We all know way too well that there are no guarantees that Cedeno will ever succeed at the ML level. Theriot has not had a great 4, 5, 6 weeks, but watching and going to the games Theriot consistently still hits to the opposite field, gets the bat on the ball, gets deep into the counts etc. If you want to try and win this year, as bad as it's been, that is not a move I think is wise.
