Back to the original topic, here are some guys solidifying themselves as good prospects or becoming them:
C. Marrero - Does nothing but hit. Great for an undrafted guy. His spits away from home are impressive.
B. Short - Just rakes.
T. Doyle - Projects as a 5th starter/swingman at best, but he's made some strides.
D. Viciedo - He's put it all together. Definitely a Top 100 prospect.
A. Rienzo - I think that the Sox organization is making him develop his offspeed pitches more, hence the high walk totals. I'd keep a close eye on his second half to see if he progresses. Really big upside, though.
