Megill has reverse splits. They probably feel confident he can get out of the 1st against Busch and Tucker. Then save Ashby for a high leverage inning against the top of the lineup later in the game.
I did not expect Pomz of all the choices to get the 1st 3 outs. I did not expect him to last longer than 2 weeks on this team so hopefully he continues to surpass my expectations.
