I think Hinch's decision to start McCullers in Game 4 is smart. He's not likely to go past 5 innings, anyway, when you can go to Peacock, Musgrove and the pen. I think he could have ggone Peacock, and then follow with McCullers, and I'd feel the same way.
The worst thing would have been rushing Keuchel into a Game 4 start on three-days -- which he's never done. At least now, Keuchel and Verlander pitch on normal rest, and that gives Houston it's best chance
If this goes seven games, it's Morton and kitchen sink
