You could say the same thing about every single team in baseball regarding an ace. It was the hitting that let them down this postseason. The Yankees scored: 7, 2, 1, 3, 4, 4 in the 6 games this series and left countless runners on base.
I think the Yankees post season managerial strategy needs to change. You can't burn your pen out by Game 3 of the ALCS. You just have to trust your starters to give your more length than the Yankees are asking.
It doesn't matter if it was Randy Johnson or Kei Igawa out there, the leash for Tanaka, Severino, and Paxson was absurdly short. It's not sustainable.
Regarding Urshella, I think his hitting this year was perhaps a 1 year wonder. There is nothing in his career that would indicate he's anywhere near this type of performer. That said, if he plays D and keeps the strikeouts down, he's fine.
I'd be fine with trying Andujar out at 1B, LF, Dan Hurley. Ideally I'd like to roll into next season with:
3B - Urshella
SS - Didi
2B - Gleyber
1B - DJ / Andjuar / Voit
Dan Hurley - Andujar / Voit
LF - Stanton
CF - Hicks
RF - Judge
BN - Romine, Tauchman, Wade, Voit/Andujar
SP - Cole/Strasburg, Severino, Tanaka, Paxson, German
RP - Same cast of characters, plus a resigned Betances
