Ryan Kalish wasn't in the starting lineup, but he played a huge role in the comeback win.
Kalish pinch-hit for Brent Lillibridge in the top of the 10th and blasted a double to right. From there, he took third on a Dustin Pedroia's single and scored on David Ortiz's sacrifice fly.
"I can't be more happy to be a part of this win," said Kalish. "Obviously, they were playing us tight and there weren't a lot of runs scored in this series. It was just huge to help out."
As a young player, Kalish doesn't have a lot of pinch-hitting experience, but he likes the challenge those situations present.
"I don't really mind it," he said. "It's just another (situation) where you can show your value, your use. You go up there and just try to have something happen. You just keep it light. There's pressure, but then again, there's really none because you haven't been in the game the whole time. You're just up there trying to put a good swing on something.
"I kind of find it fun."
Matched against Brandon League, Kalish was trying to "stay aggressive, see a good pitch early -- because they're trying to get ahead. They're going to put something over the plate and I was just ready for it."

CINCINNATI - Mookie Betts doubled with the bases loaded to tie it in the eighth inning and dashed home from second base on an infield single, rallying the Boston Red Sox to a 5-4 victory Sunday over the Cincinnati Reds that moved them closer to the AL East title.
By winning 14 of its last 17 games, Boston has left virtually no opening for the second-place New York Yankees to catch up. The Red Sox, already assured a playoff spot, completed an 8-1 road trip that put them in excellent position to win a second consecutive division crown for the first time in franchise history.
Coupled with New York's 9-5 loss in Toronto, the Red Sox reduced their magic number to three. They lead the Yankees by five games with seven to play.
That means Fenway Park can start preparing for a potential celebration. Boston finishes the regular season at home with three games against Toronto and four vs. Houston.
