Phils claim Cesar Carrillo off waivers

PHILADELPHIA -- The Philadelphia Phillies have claimed right-hander Cesar Carrillo off waivers from the San Diego Padres and designated left-hander Nate Robertson for assignment.

The NL East leaders also placed right-hander Scott Mathieson on the 15-day disabled list with a back strain on Thursday. He appeared in two games this season.

Carrillo was 5-14 with a 5.60 ERA in 27 starts for Triple-A Portland. He made three starts for the Padres last year.
