Troy Patton is going to miss the 2008 season with shoulder surgery, which is the type of thing that makes you worry a lot about his future.
A couple of things on this...first, Patton was the big prize in the Miguel Tejada trade, so this makes Baltimore's return on Tejada look a lot worse.
Secondly, I recall a diary being created after Patton was called up, with much screaming about how, if Patton was promoted to the 40 man roster and called up at the end of last year, the Rangers should have promoted Eric Hurley, as well.
This is a perfect example of why you want to consider shutting down a very young pitcher who has logged a lot of innings late in the season, rather than calling him up and thrusting him into the rotation. To be clear, I'm not saying that he was injured because of the late season call-up...but there were questions at the time whether Patton would be better served shutting it down for the year rather than making his major league debut.
It is also an instance where the team is worse off because of the decision to add the player to the 40 man. Patton will spend the whole season on the 60 day d.l., most likely, which will give him a full season of service time and will make him eligible for arbitration and free agency a year earlier.
