One of four pieces the Phillies received in return from the Yankees in the Bobby Abreu trade in 2006, Monasterios has the most upside of the group. Infielder C.J. Henry asked for his release from Philadelphia and re-signed with New York; catcher Jesus Sanchez hit just .208 while repeating the Gulf Coast League; and lefthanded reliever Matt Smith had Tommy John surgery in July. Monasterios, meanwhile, won 11 games in his first taste of full-season ball. He has great life and sink on his 90-94 mph fastball and one of the best changeups in the organization. His breaking pitches remain under construction. He's inconsistent with both his hard slider and loopy curveball, and he might wind up scrapping the latter during spring training to concentrate on a three-pitch mix. His sinker gets a lot of ground balls, but he doesn't repeat his delivery very well, making all his pitches hittable when he flies open with his front shoulder and elevates them in the strike zone. Monasterios will continue to move one level at a time, opening this season in high Class A.

Another piece of the Abreu trade, Monasterios remained in the GCL with Sanchez, with both players moving across town from Tampa to Clearwater. As with most young pitchers, his best pitch is his fastball. He usually throws in the low 90s but was clocked as high as 96 mph. Monasterios pounds the strike zone and walked just six batters in 45 innings. He flashes a plus breaking ball, but it flattens out when he gets around the pitch in his delivery. He has shown some feel for a changeup, though it remains a distant third option for now.
