Red Sox claim Luis from White Sox

The Red Sox claimed right-hander Santo Luis off waivers from the White Sox on Wednesday and optioned him to Double-A Portland. In order to make room on the 40-man roster, infielder Jed Lowrie (mononucleosis) was transferred to the 60-day disabled list.

Luis, who gave up a run in three innings at Double-A Birmingham this year, spent the 2009 season with Class A Advanced Winston-Salem, going 5-4 with a 4.34 ERA and 14 saves in 47 relief appearances. The 26-year-old led Carolina League relievers with 12.7 strikeouts per nine innings and was fifth with a .227 opponent batting average.

Originally signed by the Astros as an international free agent in 2002, the 6-foot-6 Luis went 15-12 with a 3.96 ERA in his first four years in the Minor Leagues.

In another move, right-hander Boof Bonser -- who has struggled in both of his Minor League rehab starts and will be examined by Boston's medical staff before Friday's game at Fenway Park -- was returned from his rehab assignment with Triple-A Pawtucket.
