BOSTON (Interstat) — Sonny Gray pitched six strong innings, Ceddanne Rafaela delivered a two-run pinch-hit home run in the sixth inning and the Boston Red Sox defeated the Philadelphia Phillies 3-1 on Wednesday night at Fenway Park.

Gray allowed two hits and one earned run while striking out six and walking one to improve to 4-1. The right-hander retired 11 of the final 12 batters he faced before exiting after the sixth.

Aroldis Chapman earned his ninth save of the season by pitching a scoreless ninth inning, striking out three of the five batters he faced. Chapman entered with two outs in the ninth and runners on first and second after Trea Turner walked, then struck out Alec Bohm to end the game.

Tanner Banks took the loss for Philadelphia, falling to 0-3. Banks allowed three runs on five hits over two innings in relief.

The Phillies, who fell to 20-23, had won the series opener Tuesday night 2-1. The Red Sox improved to 18-24.

Philadelphia scored its only run in the third inning when Justin Crawford led off with a home run to center field, his second of the season. The blast tied the game at 1-1 after Boston had taken a 1-0 lead in the second inning on a solo home run by Trevor Story.

Story’s homer, his third of the year, came on a fly ball to center field. The shortstop finished 2-for-3 with a home run and an RBI for Boston.

The game’s decisive moment came in the sixth inning with the score tied 1-1. After Wilyer Abreu singled with one out and Willson Contreras struck out, Rafaela came to the plate as a pinch hitter for Masataka Yoshida. Rafaela hit a two-run homer to left-center field, scoring Abreu and giving the Red Sox a 3-1 lead.

Rafaela finished 1-for-1 with a home run and two RBIs. Abreu led all hitters with three hits in four at-bats, including two singles and a ground-ball single in the first inning.

Story added a single in the sixth after Rafaela’s home run, but the Red Sox did not score again. Boston stranded four runners on base for the game.

The Phillies managed only three hits in the game, all singles. Edmundo Sosa singled in the sixth inning, Alec Bohm singled in the seventh and Crawford’s home run accounted for Philadelphia’s only extra-base hit.

Boston collected eight hits, including Abreu’s three, Story’s two, and one each from Rafaela, Marcelo Mayer and Mickey Gasper. Gasper finished 1-for-3 with a hit-by-pitch but was thrown out at third on a double play in the third inning.

The game lasted 2 hours, 13 minutes in front of an announced crowd of 35,451 at Fenway Park.

Philadelphia starter Andrew Painter pitched five innings, allowing one run on three hits while striking out four and walking none. Painter was solid after the second-inning homer by Story, retiring 11 of the final 12 batters he faced before being replaced by Banks.

Banks entered in the sixth inning and immediately gave up the go-ahead homer to Rafaela. The left-hander allowed two hits total in his two innings, both to Abreu.

Garrett Whitlock pitched a scoreless eighth inning for Boston, allowing one hit and striking out one. Whitlock replaced Gray, who had thrown 86 pitches.

Justin Slaten pitched the seventh inning for Boston, allowing one hit and striking out none.

The Red Sox bullpen combined to allow one hit over three scoreless innings.

Boston’s defense turned two double plays to help Gray. In the third inning, third baseman Alec Bohm fielded a ground ball from Contreras and started a 5-3 double play, with Gasper tagged out at third by Bohm. In the eighth inning, shortstop Edmundo Sosa started a 6-4-3 double play to end the inning.

Story also made a strong defensive play, ranging to his right to field a ground ball from Kyle Schwarber in the first inning and throwing to first for the out.

Philadelphia had opportunities but could not capitalize. In the ninth inning, Schwarber walked to lead off against Chapman, but Harper struck out, Garcia struck out, Turner walked and Bohm struck out to end the game. Philadelphia left four runners on base in the game, including two in the ninth.

The Phillies had won three of their previous four games entering Wednesday, including a 6-0 shutout of the Colorado Rockies on Sunday. The Red Sox had lost three of their previous four, including a 4-1 loss to the Tampa Bay Rays on Sunday.

Boston took a 1-0 lead in the second inning when Story hit his solo home run. The Phillies tied it in the third on Crawford’s homer. After that, Gray settled down and retired 10 of the next 11 batters before allowing a single to Sosa in the sixth.

Crawford, the Phillies’ center fielder, also made a running catch on a fly ball from Gasper in the first inning.

The game’s most impactful play was Rafaela’s pinch-hit home run in the sixth inning, which broke the tie and provided the final margin. The at-bat came with one out and Abreu on first base after his one-out single. Rafaela worked the count full before connecting on a pitch from Banks and driving it over the left-center field wall.

The win evened the three-game series at one game apiece. The teams will play the finale Thursday afternoon at Fenway Park before the Phillies travel to Pittsburgh for a weekend series and the Red Sox visit Atlanta.
