The Blue Jays optioned Hatch (hamstring) to Triple-A Buffalo on Sunday.
Hatch was only up with the Blue Jays for one day after the team required a temporary sixth starter due to Saturday's doubleheader with the Orioles. He pitched the second game of the twin bill, working four innings and giving up one run on one hit and two walks while striking out three before exiting with a hamstring issue. The extent of the injury isn't yet clear, but evidently, it wasn't significant enough for the Blue Jays to move him to the 10-day injured list.
