Chris Manno, LHP: The Nationals drafted Manno out of Duke in the 26th round of the 2010 Draft as a senior sign. The lefty had spent his sophomore and junior seasons as a starter before moving almost exclusively into a bullpen role in his senior season. He's continued on as a reliever in his pro career and has had some success doing it, having made the South Atlantic League All-Star team as Class A Hagerstown's closer during his first full season.
The 22-year-old had 12 saves and a 1.04 ERA in 34 appearances with Hagerstown, using a sneaky and deceptive fastball with a decent curve and a feel for a changeup as well. He goes right after hitters, having held them to a .135 batting average this season. He's probably not a closer in the future but could start moving more quickly as a lefty setup man or specialist.
Bill Rhinehart, OF: Drafted back in 2007 (11th round) out of the University of Arizona, Rhinehart had some early success in the organization, making All-Star teams during his summer debut and his first full season. He looked like he might be a quick-to-the-big-leagues type during that '08 campaign, playing at three levels and finishing in the Arizona Fall League, where he hit well and finished fourth in the league in RBIs.
Rhinehart had some struggles over the next two seasons, appearing to stall, but he seemed to make some adjustments this season. Now 25, having played all season with Double-A Harrisburg, Rhinehart was second in the Eastern League with 21 homers as well as a .587 slugging percentage. A left-handed hitter and thrower, Rhinehart has seen ample time both at first base and in the outfield.
