MIAMI -- Clay Buchholz struck out a season-high nine batters in seven strong innings as the Boston Red Sox beat the Miami Marlins 2-1 on Tuesday.
Kelly Shoppach and Mike Aviles each drove in runs in the seventh inning to break a scoreless tie for the Red Sox, which snapped a four-game losing streak.
Buchholz (7-2) allowed one run and five hits and walked two while throwing 69 of 103 pitches for strikes.
Miami's Logan Morrison led off the bottom of the seventh with a home run cutting the deficit to 2-1, but Buchholz retired the next three to end his outing.
Vicente Padilla pitched the eighth, allowing Omar Infante and Hanley Ramirez to reach base on singles before striking out Giancarlo Stanton to end the inning.
Alfredo Aceves allowed a leadoff single to Morrison before polishing off the next three for his 15th save in 18 chances.
Marlins starter Mark Buehrle (5-7) allowed two runs in seven innings. He was looking to tie Kenny Rogers for the most consecutive wins in interleague play at 11.
In the pivotal seventh, Shoppach doubled to left-center field scoring Will Middlebrooks. Aviles followed with a single to score Shoppach.
The game was scoreless through five innings.
The Marlins had a chance to score in the first when Jose Reyes led off with a triple down the right-field line, but Buchholz struck out Infante, Ramirez and Stanton, leaving Reyes stranded at third.
Miami had another opportunity to score in the third after back-to-back, two-out singles by Reyes and Infante. Ramirez followed with a single up the middle to shortstop Aviles, whose throw to first was not in time to get Ramirez. Reyes attempted to score from second on the play, but was easily thrown out at the plate, ending the inning.
Meanwhile, Buehrle allowed just one baserunner in the first four innings -- a two-out double to Shoppach in the third.
In the fifth, Buehrle issued a lead-off walk to Adrian Gonzalez, but the threat ended when Aviles grounded into an inning-ending double play.
NOTES: Marlins center fielder Emilio Bonifacio had the stitches removed from his left thumb, on which he had surgery May 25 to repair a torn tendon. Manager Ozzie Guillen said he hopes Bonifacio can return after the All-Star break. "That's a pretty sensitive spot. He's got to get it strong," Guillen said. ... Outfielder Marlon Byrd, designated for assignment by the Red Sox on Saturday, was released. Acquired April 21 from the Cubs for RH reliever Michael Bowden, Byrd batted .270 (27-for-100) with one homer and seven RBIs in 34 games for Boston.
