My only take on it is that you can only win the game you are currently playing, not tomorrow's or yesterday's.
Thereby , Cora's dilemma was to see how to win today. Whitlock was the right choice for the 8th. but Whitlock is not a shutdown guy with 2 outs and 2 strikes. He frequently allows the leadoff guy to reach base. But after surrendering the 2nd run he finally bore down and ended the inning.
Weissert gets the close opportunity and blows . he mimics Whitlock when needing a shutdown. But Matz was the real criminal in all this surrendering a 2run HR to a LH hitter.
But maybe the real culprits are the 1-4 hitters who sucked. Keep in mind Abreu's HR was a fluke
The lineup lost this game in conjunction with the BP
