Phillies' Jeff Singer: Promoted to Double-A

Singer was promoted to Double-A Reading on Thursday, Matt Gelb of The Philadelphia Inquirer reports.

Singer, 23, was 5-2 with a 2.34 ERA, 19 saves and a 66:28 K:BB in 50 innings for High-A Clearwater. The lefty was equally effective against left-handed and right-handed batters. His strikeout ability makes him a solid relief prospect, but he'll need to work on cutting back on the free passes.
