BOSTON (CBS/AP) -- Jackie Bradley Jr. extended his career-high hitting streak to 15 games with a two-run single in Boston's six-run fourth and added a grand slam two innings later, carrying the Red Sox over the struggling Oakland A's 14-7 on Monday night.
Brock Holt hit a two-run homer, and David Ortiz had three hits and two RBIs for Boston, which has won seven of its last 10 games.
Khris Davis hit his seventh homer and drove in two runs for Oakland, which has lost 12 of 16 and fell to 1-7 this month.
Josh Reddick's club-record streak of hits in eight consecutive at-bats was stopped when he grounded out his first time up.
Clay Buchholz (2-3) gave up four runs and six hits in five innings.
Oakland scored in each of the first three innings to open a 4-1 lead before the Red Sox charged ahead with their six-run inning.
Boston chased Sonny Gray (3-4) during an inning in which the Red Sox had seven hits, two of them doubles off the Green Monster by Ortiz, and sent 11 batters to the plate.
Travis Shaw's RBI double and Bradley Jr's single tied it, and Mookie Betts doubled in the go-ahead run. Dustin Pedroia's run-scoring single made it 6-4, and Ortiz capped the rally with an RBI double against Fernando Rodriguez.
Holt homered in Oakland's bullpen the next inning, and Bradley hit his slam over a short wall in deep right.
Gray gave up seven runs and eight hits in 3 2/3 innings. He is 1-3 with a 9.61 ERA in his last four starts.
Davis' homer landed into the first row of Monster seats.
A's: Third baseman Danny Valencia left the game with tightness in his left hamstring. He just came off the 15-day DL on Friday after straining the same hamstring. . Manager Bob Melvin said infielder Chris Coghlan's back "tightened up" Sunday. He didn't start, but was inserted into the game.
Red Sox: LHP David Price (4-1, 6.75 ERA) had a bullpen session, hoping to correct his delivery after a rough start this season. "The focus -- in addition to his normal work routine -- was to try and get him to stay over the rubber a little longer and get his hands separating a little bit more in sync with his normal delivery," manager John Farrell said.
RHP Sean O'Sullivan (0-0, 0.00 ERA) is slated to make his first start in a Red Sox uniform on Tuesday night, facing Oakland's LHP Sean Manaea (0-0, 7.20). O'Sullivan last started on July 6, 2015, with Philadelphia. For Manaea, it will be his third since being recalled from Triple-A.
