The Phillies had an open roster spot with Chase Utley on the disabled list Thursday, but a poorly timed slump cost Darin Ruf a chance to get back to the majors. Ruf is hitting .103 over the last seven games heading into play Friday.
The fact that Ruf can only play in the outfield or first base also hurt his chances.
"I think the better fit was someone who could play all over the field," assistant GM Scott Proefrock told the Philadelphia Inquirer. "We’ve got two (interleague) games. It would be hard to find (Ruf) a place to play, and it probably wouldn’t be the right fit."
Ruf has a .772 on-base plus slugging percent at Triple-A Lehigh Valley, with a .262 batting average, a career-worst mark.
