Trailing 1-0 in the fifth, the Red Sox tied it against Dylan Bundy (0-2) on Benintendi’s RBI triple. They went ahead the next inning when J.D. Martinez scored on a wild pitch after reaching on third baseman Danny Valencia’s fielding error and advancing on Moreland’s double. Tzu-Wei Lin’s RBI double made it 3-1.

Cora said he never considered not pitching Sale in the conditions because the lefty had worked in the cold when he was with the White Sox.
“I think it’s tough to play anybody in these conditions,” Cora said. “Somebody that’s capable of doing it is him, he played in Chicago.
“I read an article — I think it was (in) 2016 Robin (Ventura) was his manager and said: ‘I know its miserable, but it’s a happy day when you have your ace going.'”
