It is not, in fact, just as likely for a 28-year-old player to have a breakout season as it is for a 25-year-old. Now you're absolutely right about the sample sizes involved here being pretty meaningless, but the fact of the matter is that Cedeno has a higher ceiling; it's simply not a NEW fact. First of all, welcome to the Board. Now that you're here, you not be aware of this, but I've been a long time supporter of Cedeno. I wanted him to start over Theriot all offseason. However, with Soriano out, why is it verboten to play both Cedeno and Theriot? It's not. In fact, it's almost certainly the best move for the team given Murton's struggles. I just don't think there's any reason to pitch a fit until that decision is forced on us. Age 28 seasons are typically among the peak years for a player -- Theriot could certainly be having a break-out season. I'd suggest that a 28 year old having a great season after a sub-par Age 27 season isn't unheard of. Given that 25 is pre-peak and 28 is among the peak years, I believe it is more likely for a 28 year-old than a 25 year-old to have a break-out season. I could be wrong, of course, but that's my recollection. I absolutely agree that Cedeno has higher ceiling. No question about it (in my mind). And, actually, it is Ronny's ceiling and his likely progression as a player making him more important, long-term, to the Cubs than Theriot. Even though Ryan and Ronny are providing roughly similar production, Cedeno is likely to improve and become a better player while Theriot is arguably at his peak. All that said, the sample sizes are still too small to draw any meaningful conclusions. Seems highly unlikely that a player with Theriot's background in the minors and majors would ever have a breakout season, let alone at age 28. Seems much more likely that a guy that sucked in the majors at age 23, but was great in AAA at ages 22 and 24 would breakout at age 25. Also seems like Cedeno's "breakout" (or peak) would be something like an .800-.850 OPS, whereas Theriot's would be about 100 OPS points lower.
