CHICAGO -- Jackie Bradley Jr. delivered the go-ahead hit in the ninth. His 93.8 mph single to right field scored Ian Kinsler from second base and put Boston ahead 5-4.

The Red Sox added four more runs in the ninth to win 9-4 over the White Sox here at Guaranteed Rate Field.

Bradley's go-ahead single came after he stroked game-tying hits both Tuesday and Wednesday.

Bradley is 22-for-60 (.367) with a .400 on-base percentage, 600 percentage, 1.000 OPS, six doubles, two homers, one triple and 10 RBIs in his past 17 games since Aug. 10.

He's slashing .293/.344/.512/.857 with seven doubles, three homers, one triple and 14 RBIs during August.

The center fielder has turned his season around completely after slashing .210/.297/.345/.642 in 86 games before the All-Star Break.

"It's all about him," said Red Sox manager Alex Cora who has received praise for his patience with Bradley.

"It's a credit to us because whatever, nah, nah, nah," Cora added. "It's all him because when you're hitting .180, .190, to show up every day and play the way he was playing, that's hard to do. And he stayed with it. It's good to see him smiling now and enjoying the game. It's hard to enjoy the game when you're hitting .190. But now you can see that he's very confident and he's doing an outstanding job."

Bradley had an ugly .161/.261/.242/.502 slash line May 19. But he has been hitting the ball hard all season.

He ranks 20th in the majors in average exit velocity (91.8 mph), per Baseball Savant.

An increase in shifts against him have caused some hard hit balls to turn into outs.

"It's just frustrating knowing just the work that you put in," he said. "And you see yourself doing the things you want to do like hitting the ball hard and all that good stuff but not being able to get the results sometimes. It can be frustrating and mentally draining. But you've got to tough through it. You've got to be mentally strong and continue to work."

Bradley has been at his best batting ninth in the order with an .803 OPS there.

"Sometimes I feel tempted to move him up in the lineup, but I do feel like in that spot he gets a lot of traffic," Cora said. "Those guys get on base and he's driving in runs. And he's also getting on base for those guys on top of the lineup. So he's been great."
