I think "implosion" is an oversell here. Ottavino has an ugly ERA, true, but the rest of the regular NY pen has been pretty solid. Team regular season bullpen ERA is misleading when evaluating a playoff matchup, because there are usually a few poor performers at the bottom of the pen who won't even sniff the playoff roster. The top 6 Yankee bullpen performers have a cumulative 3.09 ERA; the top 6 Twins, 2.70. And even that might overstate the difference -- one of the Yankees top 6, Chapman, missed the first month of the season with COVID-19 and gave up 4 runs in his first 4 IP. Since then, he's been extremely dominant: 5.2 IP, 1 H, 0 R, 2 BB, 13 K. Ottavino is a bit of an odd case too -- I know you can't just throw out a player's worst game, but his worst game is an extreme outlier: he was charged with 6 runs without retiring a batter! Suffice to say, if he's utilized in the postseason, I assume he won't be allowed to let 6 batters reach without retiring any of them.
