BOSTON -- David Ortiz homered twice and the Boston Red Sox returned to .500 with an 11-6 victory over the Oakland Athletics on Monday night.
Darnell McDonald and Mike Aviles also homered for Boston, and Clay Buchholz (3-1) pitched six solid innings before a minor collapse in the seventh allowed Oakland to get back into it.
The Red Sox won for the seventh time in eight games and finished the opening month at 11-11 despite starting the season 1-5. Boston also snapped a five-game home losing streak and scored 10 or more runs for the seventh time this season.
Josh Reddick hit a three-run homer for Oakland, which lost its third straight.
The Red Sox scored four runs in the second, two in the third and then five in the fifth while chasing Oakland starter Tommy Milone (3-2) after 4 2/3 innings.
It appeared to be more than enough offense as Buchholz was cruising with an 11-1 lead before getting tagged for five runs in the seventh. Coco Crisp hit a bases-loaded single with two outs, driving in the first runs Buchholz allowed since the first inning. Reddick, playing his first game in Boston since the Red Sox traded him in the offseason, followed with a homer to cut Boston's lead to 11-6. Buchholz pitched 6 2/3 innings, allowing six runs on seven hits while striking out five and walking five.
Reliever Junichi Tazawa allowed a single, then hit a batter before an error by third baseman Nick Punto on a pop up loaded the bases. Vicente Padilla replaced Tazawa and got a mock cheer when he threw a strike after falling behind 2-0 against Daric Barton. Padilla came up with two more strikes to get Barton looking and finally end the A's rally.
Oakland loaded the bases again in the eighth with nobody out, but failed to score a run. Crisp struck out, then Reddick grounded to second for a double play. The A's left 10 runners on base.
Brandon Inge, released by Detroit last week and signed by Oakland earlier Monday, went 1-for-3 with a walk in his debut for the A's.
Ortiz hit a line drive into the Oakland bullpen for a solo homer in the second, then drove another one out with a towering fly in the fifth to put Boston up 7-1. Reddick backed up to the wall and got his glove on it, but couldn't hang on and the ball dropped for Ortiz's sixth homer of the season. That was all for Milone, who allowed eight runs (seven earned) and eight hits in 4 2/3 innings.
Aviles added a three-run homer over the Green Monster off of reliever Jordan Noberto later in the fifth to put Boston up 11-1.
The Red Sox took a 4-1 lead in the second on Ortiz's first homer of the game, followed by RBI singles by Marlon Byrd and Aviles. McDonald, who doubled and scored during Boston's rally in the second, hit a two-run homer in the third to put Boston up 6-1.
Ortiz started a four-run rally for Boston in the second with a solo homer to right, tying the game at 1-1. McDonald hit a ground-rule double to the gap in right-center with one out and scored on Byrd's sharp grounder that got past second baseman Jemile Weeks. Byrd scored on Aviles' two-out single to center, then Boston added another run when Weeks made a bad throw to first on a grounder by Adrian Gonzalez. That made it 4-1.
Oakland had a chance in the second inning, loading the bases on a single with two on and two out, but Daric Barton got caught when he rounded second too far after Cliff Pennington's single. He lasted long enough in a rundown for Kurt Suzuki to score from third and give Oakland a 1-0 lead.
