Chapman gives the club a second southpaw option out of the 'pen and potentially a useful one for Friday's game, since lefty Tony Sipp pitched a full inning for the second time in three days and may be unavailable. The 27-year-old has 46 career appearances in five stints with the Astros, sporting a 3.24 ERA in 41 2/3 innings of work.
Hoes heads back down to Fresno just four days after being called up to the Majors for the first time this season. He went 0-for-1 with a run scored in two games at San Diego during his brief stint. With a crowded outfield, it may take an injury for him to make it back if the Astros decide to keep a deep bullpen.
