HOUSTON (AP) The Houston Astros have placed right-hander Charlie Morton on the 10-day disabled list with a strained muscle in the right side of his back.
The Astros say there is no timetable for his return from the lat ((latissimus dorsi) injury.
Morton is 5-3 with a 4.06 ERA in 10 starts this season in his first year in Houston.
The move comes a day after ace Dallas Keuchel came off the disabled list after missing one start with a pinched nerve in his neck.
Houston called up right-handed reliever Jordan Jankowski from Triple-A Fresno to take Morton's spot on the roster.
