The Houston Astros have claimed right-hander Cesar Carrillo off waivers from the San Diego Padres.

The Astros designated infielder Edwin Maysonet for assignment on Wednesday to make room for Carrillo on the 40-man roster.

The 26-year-old Carrillo won't join the Astros' major league club in 2010.

He was a first-round pick in the 2005 amateur draft and went 1-2 with a 13.06 ERA in three starts for San Diego in 2009. Carrillo was 5-14 in 27 starts at Triple-A Portland this year.

San Diego originally designated Carrillo for assignment Sept. 1, and Philadelphia claimed him eight days later. But the Phillies waived him, and the Padres briefly reclaimed him.

Maysonet didn't play for Houston in 2010. He hit a combined .276 in 76 at-bats in 2008 and 2009.
