It seems so long ago, but there was a period of time during the 2020 season when Zack Greinke looked like the unquestioned ace of the Houston Astros rotation. Justin Verlander was injured, Lance McCullers wasn’t quite himself and Framber Valdez hadn’t yet emerged into the ace he turned out to be.
Greinke never stopped being one of the most important pitchers on the staff, but it’s hard to ignore the fact that he regressed a bit. Now he doesn’t look quite as much like an ace, but more like a mid-rotation starter. Is age finally catching up to him?
