The Houston Astros are reportedly shopping starter-turned-reliever Brett Myers, according to USA Today.Houston moved Myers from the rotation to the bullpen this season, allegedly to improve his trade value. The Astros are hoping to attract teams that have struggled in the ninth inning to start the season. The San Francisco Giants are one of the team's rumored to be interested after losing closer Brian Wilson for the year. Myers has picked up saves in both of his relief appearances this year, posting a 0.00 ERA through two innings of work. Last season, the right-hander went 7-14 with a 4.46 ERA in 33 starts for Houston. He was last used out of the bullpen by the Philadelphia Phillies in 2007, when he recorded 21 saves.
