This 5-4 victory by the Red Sox over the Yankees on Sunday night was set up by one defining moment in the bottom of the fifth inning.
CC Sabathia snared a liner by Mookie Betts and should have had an inning-ending double play. But the lefty's throw to first base was high, and Billy Butler couldn't reel it in.
At this moment, the Red Sox were down, 4-0.
