To make room for Keppinger, the Giants transferred Freddy Sanchez to the 60-day disabled list with a dislocated shoulder. With Miguel Tejada exiting last night's game with an abdominal injury, the team wasted no time in finding an affordable replacement should Tejada join fellow infielders Freddy Sanchez and Bill Hall on the disabled list.
The Giants dealt two right-hand pitchers to the Astros in exchange for Keppinger.
25-year-old Henry Sosa had struggled at Fresno this year, posting a 10.42 ERA and a 2.40 WHIP. He was with AA Richmond at the time of the trade. Sosa had been with the Giants organization since 2006 -- appearing in the 2007 Futures Game at AT&T Park -- and spent all of 2010 with Fresno.
Astros general manager Ed Wade told reporters on Tuesday that Sosa could be in the Astros rotation as early as next year.
Jason Stoffel was the other right-hander shipped to Houston in the deal. The 22-year-old was drafted by the Giants in 2009 out of the University of Arizona. Stoffel -- who was ranked as the Giants #22 prospect by Baseball America -- had closed out 25 games for San Jose in 2010. This year he had been sharing closing duties in Richmond with Heath Hembree.
Stoffel, whose main weapon is an overpowering fastball, had good strikeout numbers at Richmond. In 32 appearance for the Flying Squirrels, he had posted a middling 1.58 WHIP with a K/BB ratio of 31/16.
