Astros claim pitcher Lopez off waivers
Former Padres, Yankees hurler optioned to Double-A
ST. LOUIS -- The Astros added a right-handed pitcher to their organization on Friday, claiming Wilton Lopez off waivers from the Padres. They optioned him to Double-A Corpus Christi, and, to make room for him on the club's 40-man roster, transferred infielder Aaron Boone to the 60-day disabled list.
The 25-year-old Lopez has a 6-5 record and a 4.13 ERA and 16 saves over 111 relief appearances during three Minor League seasons with the Padres and Yankees organizations. In 2008, he pitched at three levels within the Padres farm system: Class A Lake Elsinore, Double-A San Antonio and Triple-A Portland, making a combined 58 relief outings.
Lopez was originally signed by the Yankees as a non-drafted free agent in 2002.
Boone, 36, underwent heart surgery last month and is expected to be out the entire season.
