It has been a pretty disappointing year for some of the Red Sox's prospects: Downs: isn't really a legitimate prospect anymore. Mayer: looks very pedestrian so far. Casas: has been hurt, probably won't be ready for the major leagues next year. Yorke: we were so high on Yorke, I'm not sure what happened to him, but maybe he will finish strong. Groome: was hoping he would take a big step forward, but that walk ratio is unacceptable, maybe a bullpen piece in the future.
On the other hand, Rafaela has been really good. Murphy has been pretty good. Duran is finally getting a chance in the majors and looks like he belongs, and Bello looks awesome. In fact, you could make the case that Bello is the Red Sox best prospect, the one that has the most trade value right now. Blaze looks really good too.
Binelas is a mixed bag, hit with power, but his defense isn't very good, and it looks like his only tool might be power. We will see how he does at AA.
Winckowski & Seabold = reason for optimism.
Lugo & German have been OK.
