The commissioner's office returned Phillies right-hander Brian Schlitter to the Cubs because of past injury, according to Matt Gelb of the Philadelphia Inquirer (on Twitter). The Phillies claimed Schlitter from the Yankees in February, a month after the Yankees claimed him from the Cubs, but those claims are now void.
The Phillies placed Schlitter on the disabled list with a right flexor pronator strain at the end of Spring Training, retroactive to March 22nd. He has yet to appear in a pro game this year.
Schlitter appeared in seven games for the Cubs last year and gave up 18 hits and five walks in eight innings, striking out seven. He spent most of the season at Triple-A Iowa, where he posted a 3.15 ERA with 8.3 K/9 and 4.1 BB/9 in 45 2/3 innings in his first season at the highest level of the minors.
