Tyler O'Neill went 3-for-5 with two RBIs to help the visiting Boston Red Sox recover for a 6-5 win in 12 innings and sweep the Miami Marlins on Thursday.

Romy Gonzalez, the automatic runner in the 12th inning, scored on a groundout, and O'Neill's double drove in Ceddanne Rafaela to put Boston ahead 6-4.

Vidal Brujan scored on a sacrifice fly to pull the Marlins within one in the bottom of the inning, before Greg Weissert got the final two outs for his first career save.

Red Sox reliever Zack Kelly (3-1) allowed two runs (one earned) on one hit in two innings, and Weissert gave up an unearned run on two hits. Starting pitcher Nick Pivetta one-hit Miami through seven innings, with 10 strikeouts and a pair of walks.

Boston has won four in a row.

Miami reliever Matt Andriese (0-1) gave up the go-ahead runs in the 12th. The Marlins have lost four straight.

The Red Sox went ahead 4-2 in the 11th when Jarren Durran, the automatic runner, scored on O'Neill's infield single, and O'Neill crossed on a single by Enmanuel Valdez.

The Marlins tied it in the bottom half when Jesus Sanchez blasted a two-run shot off Kelly to center field, scoring automatic runner Josh Bell.

Reliever Justin Slaten took over for Pivetta to start the eighth, and Miami took advantage. Brujan and pinch hitter Nick Gordon each drew a one-out walk. Brujan advanced to third on a wild pitch and scored on Jazz Chisholm Jr.'s single. Bryan De La Cruz singled to knock in Gordon and tie the game at 2-2.

Sanchez busted Pivetta's no-hitter in the seventh, connecting on a first-pitch fastball for a triple off the center field wall.

In the sixth, David Hamilton hit a one-out single and O'Neill walked, prompting Marlins manager Skip Schumaker to turn to his bullpen. Rafael Devers then came to the plate to face A.J. Puk, and Hamilton and O'Neill managed a double steal for the second time on the afternoon. Hamilton scored on Devers' groundout to make it 2-0.

Boston took a 1-0 lead in the first. With Hamilton and O'Neill on with one out and Devers at the plate, the duo pulled off a double steal. Three pitches later, Devers hit a groundout against Marlins starter Kyle Tyler that brought in Hamilton.

Connor Wong, who entered the game as a pinch hitter in the 10th, had his 17-game hitting streak snapped.
