Zack Wheeler and Zac Gallen are the two aces of these teams, but Merrill Kelly and Aaron Nola are about as good of #2s as you can have. They have had incredible postseasons, and both were great in the regular season.
Aaron Nola finished this season with an ERA of 4.46, the highest ERA the D-backs have seen this postseason, but Nola has been great in the postseason. He has only allowed two runs this postseason and only allowed 14 runs in the postseason last year. He, like Wheeler, is dominant at Citizens Bank Park.
In his only start versus the Diamondbacks, Nola allowed four earned runs in 6.
