NEW YORK (Interstat) — The Boston Red Sox scored two runs in the ninth inning to tie the game and pushed across the winning run in the 10th to defeat the New York Mets 3-2 on Sunday afternoon at Citi Field, completing a three-game sweep.

The Red Sox entered the ninth inning trailing 2-0, having managed only two hits against Mets starter Zach Thornton, who dominated over seven scoreless innings. Thornton allowed just two singles, walked one and struck out five. But Boston broke through against reliever Devin Williams.

Ceddanne Rafaela led off with a line-drive single to left field. After Wilyer Abreu popped out to second baseman Zack Short, Romy Gonzalez reached on a fielder’s choice, with Rafaela advancing to second when shortstop Francisco Lindor committed a fielding error. Caleb Durbin walked to load the bases, and Andruw Monasterio drew another walk to force in the first run, trimming the deficit to 2-1. Jarren Duran then singled to right field, scoring pinch runner Tsung-Che Cheng and tying the game at 2. Masataka Yoshida lined into a double play, second baseman Short to shortstop Lindor, to end the inning, but Boston had erased the two-run deficit.

In the 10th, Yoshida started as the ghost runner on second base under extra-innings rules. Connor Wong sacrificed him to third with a bunt, and Anthony Seigler lifted a sacrifice fly to left fielder Tyrone Taylor, scoring Yoshida to give Boston a 3-2 lead.

Garrett Whitlock worked a perfect bottom of the 10th. He struck out Jorge Polanco swinging, then retired Brett Baty on a flyout to left fielder Yoshida and Bo Bichette on a groundout to first baseman Monasterio to earn his second save of the season.

The Mets had taken a 1-0 lead in the first inning. A.J. Ewing doubled on a ground ball to second baseman Anthony Seigler and scored on a double by Lindor, a sharp line drive to left field. Lindor added a solo home run to left-center field in the sixth inning, his fifth of the season, making it a 2-0 lead.

Lindor finished 2-for-4 with a double, a home run and two runs batted in. He was the lone bright spot for the Mets offense, which managed six hits but went 0-for-3 with runners in scoring position after the first inning. New York also left five runners on base.

Boston’s four hits included Rafaela’s single, Duran’s game-tying single, a double by Monasterio in the fifth inning and a single by Wong in the sixth. The Red Sox executed two sacrifice hits: a bunt by Durbin in the second inning that moved Romy Gonzalez to second base, and a bunt by Wong in the 10th that advanced Yoshida to third. Seigler’s sacrifice fly accounted for the winning run.

Aroldis Chapman earned the win, improving his record to 1-3, after pitching a scoreless eighth and ninth innings. He allowed one hit, a single by Jared Young in the ninth, and struck out one. Thornton did not factor in the decision despite his stellar outing. Williams took the loss, falling to 4-4, after allowing two runs on two hits with a walk in one inning. For Boston, Brayan Bello started and threw six innings, yielding two runs on four hits with seven strikeouts and two walks.

The Mets had a chance to win in regulation. In the bottom of the ninth, after Lindor popped out, Jared Young singled sharply to right field. But Carson Benge struck out and Tyrone Taylor flied out to left, sending the game to extra innings.

The game lasted 2 hours, 33 minutes in front of 37,638 fans at Citi Field.

Boston improved to 46-48, winning its third straight game and fourth in its past six. The victory completed a series sweep, following wins of 4-0 on Saturday and 6-2 on Friday. The Red Sox outscored the Mets 13-2 over the three games.

New York fell to 40-57, losing its fifth consecutive game and its sixth in the past seven. The Mets have lost 12 of their past 15 at home.

The Red Sox return home for a 10-game homestand beginning Friday against the Tampa Bay Rays. The Mets travel to Philadelphia for a three-game series starting Friday.
