BOSTON (Interstat) — Max Muncy doubled in the go-ahead run in the top of the ninth inning, and the Athletics held off the Boston Red Sox 4-3 on Sunday at Fenway Park. The Athletics improved to 47-71 with their second straight win in the three-game series, while the Red Sox dropped to 64-53. Attendance was 36,817, and the game lasted 2 hours, 38 minutes. The Athletics finished with nine hits, and the Red Sox had six.

The decisive portion of the game came in the final two innings. After Boston carried a 3-2 lead into the eighth, the Athletics tied the game on Jonah Heim’s double. Then in the ninth, Muncy delivered the go-ahead hit, and Hogan Harris navigated a tense bottom half to secure the save. The most important part of the game was the Athletics’ ninth-inning rally and Harris’ response under pressure in the bottom half.

The Athletics started the scoring in the first inning. Henry Bolte singled to center against Boston opener Erik Miller, and Jacob Wilson followed with a bunt single. Miller threw the ball away on Wilson’s bunt, allowing Bolte to reach third and Wilson to move to second. Jonah Heim struck out, but Tyler Soderstrom grounded out to first base, scoring Bolte. Tommy White struck out to end the inning, but the Athletics led 1-0.

Boston tied the game in the second against J.T. Ginn. Willson Contreras was hit by a pitch, and Anthony Seigler singled to center. Eli White then lined a single to right, scoring Contreras. Jarren Duran popped out and Jake Rogers lined out, and the game was level at 1.

The Athletics moved back in front in the fourth. Soderstrom tripled to right field, his third triple of the season, and Tommy White followed with a groundout that scored him. Lawrence Butler grounded out, Carlos Cortes singled, and Max Muncy grounded into a force play to end the inning. The Athletics led 2-1.

Boston answered with a two-run fifth. Eli White reached on a soft bunt single, and Jake Rogers singled to left, putting White at third. Nick Sogard then reached on a fielder’s choice, with White scoring and Rogers moving to third. A throwing error by Ginn on the play allowed Sogard to take second. Ceddanne Rafaela grounded out, and Wilyer Abreu followed with a sacrifice fly to right, scoring Rogers. Contreras was hit by another pitch, but Andruw Monasterio grounded out to end the inning. The Red Sox led 3-2.

Ginn continued into the sixth and retired the side while working around a two-out single by Eli White. Brady Basso then pitched a clean seventh for the Athletics, setting down Nick Sogard, Rafaela and Abreu in order. That kept the Athletics within one run and set up the late comeback.

The Athletics tied the game in the eighth off Garrett Whitlock. Jeff McNeil singled to third to lead off the inning. Henry Bolte struck out and Jacob Wilson struck out, bringing Heim to the plate with two outs. Heim doubled to left, scoring McNeil from first and knotting the game at 3. Tyler Soderstrom struck out to end the inning, but the Athletics had new life.

In the top of the ninth, the Athletics went in front against losing pitcher Aroldis Chapman. Tommy White flied out and Lawrence Butler flied out, giving Boston two quick outs. Alika Williams then singled to right field. Donovan Walton entered as a pinch runner, and Muncy followed with a double to center, scoring Walton and giving the Athletics a 4-3 lead. Jeff McNeil walked after the double, but Henry Bolte grounded out to end the inning.

The bottom of the ninth brought immediate pressure for Harris. Jahmai Jones singled to left to start the inning. Eli White struck out after a challenge confirmed the call, and Caleb Durbin walked after a challenge overturned the call, putting Jones at second. Nick Sogard then grounded into a force play, with Max Muncy fielding at third and erasing Jones at third. Durbin moved to second, and Sogard reached first. Rafaela stepped in with two runners on and lined out to left fielder Jeff McNeil, ending the game and giving Harris his 11th save.

Ginn was the top star for the Athletics, allowing five hits and one earned run over six innings while striking out two. He did not factor into the decision, but he kept the Athletics within reach after Boston’s two-run fifth. In his previous start, Ginn allowed three earned runs over six innings in a loss at Cincinnati, and his return to a quality start was a major factor in the Athletics’ victory.

Boston’s Brayan Bello was also key, working four innings in relief of Miller and allowing three hits and one earned run while striking out four. Bello gave Boston length and kept the Red Sox in the game during the middle innings. Miller opened and allowed two hits and no earned runs over one inning with two strikeouts, though his throwing error in the first contributed to the Athletics’ first run.

Whitlock took the tying run in the eighth, allowing two hits and one earned run over one inning while striking out three. Tyron Guerrero and Jovani Morán each pitched a scoreless inning for Boston with one strikeout. Erik Miller, after opening, did not return. Aroldis Chapman took the loss and fell to 2-4 after allowing the go-ahead run in the ninth.

Elvis Alvarado earned the win for the Athletics, improving to 4-3. He pitched a scoreless eighth with one strikeout, keeping the game tied for the Athletics’ late rally. Harris allowed one hit and one walk in the ninth while striking out one and earned his 11th save. Heim, who drove in the tying run, finished 1 for 4 on the afternoon.

The Athletics had nine hits in the game, while the Red Sox had six. The win gave the Athletics their second straight victory after they lost Friday’s series opener by a 13-1 score. Saturday, the Athletics won 7-3, and Sunday’s result secured the series victory over Boston. The Athletics will return home to face Tampa Bay, while the Red Sox will travel to Toronto for their next series.

Interstat’s game simulator had projected a 7-1 victory for Boston, and Interstat’s ELO system gave the Red Sox a 71.60 percent chance to win. Boston was installed as a 1.5-run favorite. The combined total of seven runs was below the 10.5 over/under line.
