Mark Appel, whose fastball velocity was down considerably in the first inning of his last start, was placed on the disabled list Friday with a shoulder strain.
Appel, 24, is 3-3 with a 4.46 ERA and 1.57 WHIP in eight starts for Triple A Lehigh Valley in his first year in the Phillies' system. He's struggled his last four times out, allowing 18 runs (15 earned) in 16⅓ innings on 20 hits and 11 walks.
The No. 1 overall pick in 2013 out of Stanford, Appel has had a disappointing pro career to this point. In 62 minor-league games (61 starts), he has a 5.04 ERA. The Phillies acquired him from Houston as part of the Ken Giles trade this past winter.
Appel's trip to the DL creates an opportunity for right-hander Ben Lively, who was promoted from Double A Reading to Triple A to take Appel's place in the IronPigs' rotation. Lively, acquired from the Reds for Marlon Byrd prior to the 2015 season, is 7-0 with a 1.87 ERA this season.
Rehab updates
Leftfielder Cody Asche and left-handed reliever Mario Hollands had their rehab assignments transferred to Triple A Lehigh Valley.
Asche is 5 for 34 (.147) with two home runs and 12 strikeouts during his stints with Clearwater and Reading.
Hollands has been sharp, posting a 1.04 ERA in 8⅔ innings with 12 strikeouts and one walk.
