BOSTON — David Price went home a winner in a postseason start for the first time in his career.

That, he insisted, is all he ever cared about.

“This is bigger than David Price,” he said Sunday night. “This isn’t about me. This is about the Boston Red Sox.”

Price was good enough, the relievers were even better, and Jackie Bradley Jr. delivered a go-ahead, three-run double off the Green Monster to lead the Red Sox to a 7-5 victory over the Astros, tying the AL Championship Series at one game apiece.

Price fell one out short of qualifying for the win, which would have been his first in 11 postseason starts. But it was the first time his team had won a playoff game he started, snapping a record run of futility.

“It’s baby steps,” said Price, who entered the night 0-9 in 10 career playoff starts.

Game 3 is Tuesday in Houston, followed by two more at Minute Maid Park and a chance for the defending World Series champions to clinch a second straight AL pennant at home. Marwin Gonzalez homered for the Astros, who had won five straight postseason games since Game 7 of the 2017 Series.

Price was spotted a two-run lead in the first inning and then fell behind 4-2 before Bradley clanged one off the left-field wall.

Price left leading 5-4 with two on with two outs in the fifth before Matt Barnes struck out Gonzalez to end the inning and then pitched a perfect sixth to earn the victory. Ryan Brasier pitched a scoreless inning, and Rick Porcello set the Astros down 1-2-3 in the eighth.

Closer Craig Kimbrel gave up Jose Altuve’s RBI single with two outs in the ninth before Alex Bregman launched a high fly to left that Andrew Benintendi caught a step in front of the Monster.
