ANALYSIS
Martinez spent spring training with Detroit and became available when released over the past weekend. The right-hander returns to the organization that originally signed him as an international free agent out of Venezuela back in 2005. In two minor-league stops last season, for the Twins and Tigers, the 29-year-old Martinez had a combined 5.96 ERA in 92.2 innings. He should serve as nothing more than starting depth with the Astros this season.
