Houston — Tigers manager AJ Hinch said before the game Saturday that right-hander Matt Manning was ready to begin his rehab assignment.
Manning, out since April 17 with shoulder inflammation, is expected to start for Triple-A Toledo on Sunday.
He left his start on April 16 after two innings and has been throwing in Lakeland the last two-plus weeks.
"The timetable will be determined how he does," Hinch said.
Manning's last full start was April 11, so most likely he would need three rehab starts to build back up toward 100 pitches.
Right-hander Casey Mize (elbow strain) took a big step in his rehab process on Saturday.
