WASHINGTON -- Nothing is wrong with Jesse Biddle, but the Phillies did scratch their No. 9 prospect from Friday's scheduled start with Double-A Reading because they want him to work on his mechanics. He is scheduled to rejoin the rotation next Tuesday.
The Phillies selected Biddle in the first round of the 2010 First-Year Player Draft, and this is his third season with Reading. Injuries have limited him in the past, but the organization clearly was hoping for a big step forward this season.
Biddle is 3-1 with a 4.84 ERA in seven starts this season. He has a 1.585 WHIP, which is the highest rate of his professional career.
The Reading rotation includes right-handers Aaron Nola (6-2, 1.54 ERA in eight starts), Zach Eflin (3-3, 2.74 ERA) and Ben Lively (3-1, 3.50 ERA); and left-hander Tom Windle (0-3, 5.35 ERA). The Phillies selected Nola, their No. 2 prospect, in the first round of last year's Draft. They acquired Eflin (No. 5), Lively (No. 7) and Windle (No. 6) in trades for Jimmy Rollins and Marlon Byrd.
Windle has struggled so far, but there is some thought his arm might eventually play bigger in the bullpen.
