Nick Kurtz walked to load the bases, but Wilson popped out to second to leave the inning with the Athletics ahead 3-0.

Boston broke through in the fifth against Athletics starter Mason Barnett. Caleb Durbin was hit by a pitch and advanced to second on Jarren Duran’s groundout. Andruw Monasterio singled to center, scoring Durbin. Connor Wong struck out, but Anthony Seigler singled to put two runners on. Ceddanne Rafaela then doubled to left, driving in Monasterio and Seigler. Rafaela advanced to third on a throwing error by shortstop Donovan Walton. The inning ended when Abreu flied out, but the game was tied at 3.

The Athletics regained the lead in the sixth. Butler doubled to center, moved to third on McNeil’s flyout and scored on Cortes’ sacrifice fly to left.

Boston went back in front in the eighth against reliever Luis Medina. Abreu led off with a homer to center, his 16th of the season. Willson Contreras followed with his 23rd homer, also to center, giving the Red Sox a 5-4 lead. Medina (2-2) took the loss after allowing the two home runs in relief of Barnett.

Barnett lasted five innings and allowed three earned runs on four hits with six strikeouts. Scott Blewett followed with two scoreless innings, giving up two hits and striking out one. Elvis Alvarado pitched a scoreless eighth, allowing no hits and striking out one.

The Athletics grounded into two double plays. The first came in the third when Soderstrom grounded into a game-ending double play. The second came in the eighth, after Heim singled and Henry Bolte entered as a pinch runner, when Tommy White grounded into a double play to erase the baserunner.

Boston’s bullpen combination of Weissert and Chapman preserved the one-run lead. Chapman allowed a one-out double to Alika Williams in the ninth but recovered. Colby Thomas was called out on strikes after a challenge confirmed the call, and Nick Kurtz struck out swinging to end the game.
