Flaherty (ankle) is expected to return from the 15-day injured list to start Sunday against the Astros, Chris McCosky of The Detroit News reports.
Flaherty was sharp in his rehab start with Double-A Erie on Tuesday, striking out seven while holding the opposition to two runs over 5.2 frames. He got his pitch count up to 83, so Flaherty should be prepared for a relatively normal workload Sunday. With Keider Montero pitching well, the Tigers could stick with a six-man rotation once Flaherty returns, at least for one turn.
