The dramatic 5-4 win capped a vicious Red Sox comeback in the storied American League East rivalry. Boston (79-34) trailed New York (68-42) 4-1 entering the ninth inning.
Yankees fireballer Aroldis Chapman came in to close out the victory, kicking off his relief appearance with a strike out of Brock Holt. Then he came unravelled. Chapman walked Sandy Leon and Mookie Betts before striking out Benintendi. He then walked Steve Pearce to load the bases.
Red Sox star J.D. Martinez smacked the first pitch he saw from Chapman for a line drive single to center field, scoring Betts and Leon.
Red Sox reliever Matt Barnes put out the Yankees in order to begin the 10th frame. Jonathan Holder then came in to replace Chapman.
Holder struck out Eduardo Nunez before getting Brock Holt to ground out. Leon took another walk in the next exchange before Holder tossed a wild pitch too Betts, allowing Leon to advance to second base.
Holder intentionally walked Betts and the Red Sox sent in Tony Renda to run for Leon. Holder tossed consecutive balls to Benintendi in the next at-bat. He then tossed in a 93 mph fastball for a strike. Benintendi smacked his next offering for a ground ball single to center field, scoring Renda from second base and winning the game.
