Brett Sinkbeil

Sinkbeil dealt with some forearm problems in 2007, limiting him to 14 starts at High-A and delaying his ascent up the Marlins' organizational depth chart, but he pitched in winter ball and seemed fully healthy. He's got a good three-pitch arsenal (low-90s fastball, slider and change-up, although none are truly outstanding pitches) and very good control, which gives him the upside of a solid mid-rotation starter. He'll need to prove he can hold up under a full workload before he'll rejoin the ranks of the Marlins' top pitching prospects, however.

Sinkbeil's first season as a pro was something of a mixed bag. The 19th overall pick in 2006 proved too much for New York-Penn League batters to handle but sagged after a promotion to Low-A, likely due to fatigue. The Marlins will use 2007 to get him used to the rigors of a long season, and assuming no bumps in the road he should finish up the year in Double-A, with the majors on the horizon in 2008. Whether there are any rotation openings at that time, given all the pitching talent in the organization, remains to be seen.
