The Astros hope McCullers' (back) rehab start Wednesday will be his last before he is activated, Jake Kaplan of the Houston Chronicle reports.
If it is indeed his final rehab start, he would presumably return to the rotation Monday or Tuesday in Seattle. He gave up three runs on three hits and five walks in three innings in his last rehab start, throwing 33 of his 59 pitches for strikes. Upping his pitch count and walking fewer batters in his second rehab start will be two key factors to check on to see if McCullers is trending toward joining the rotation early next week.
