BOSTON — The Boston Red Sox entered Saturday with a chance to etch their name deeper into the franchise record books. Instead, they walked off the field at Fenway Park watching the Oakland Athletics celebrate a much-needed victory. The Red Sox fell 7-3, ending their bid to become the first team in the club's 126-year history to post two separate winning streaks of 10 or more games in the same season.

Boston's earlier 15-game winning streak, which tied the 1946 franchise record, was halted on July 22. The team then rebounded with a nine-game run that began the day after that loss. But the Athletics, desperate to snap a nine-game skid of their own, proved to be a stubborn obstacle.

Gage Jump, the Athletics' left-handed starter, was the central figure. He had beaten the Red Sox on July 28 with six scoreless innings, and on Saturday he was even sharper. Jump (5-7) struck out a season-high 11 batters over six innings, allowing two runs on six hits. He walked only one and kept Boston's hitters off balance with a mix of fastballs and breaking stuff.

The Red Sox struck first. In the bottom of the first inning, Andruw Monasterio delivered a two-run single, giving Boston an early 2-0 lead. It seemed the Red Sox might carry that momentum through the early frames. Starter Jake Bennett (7-5) cruised through the first three innings, allowing only a walk. But the Athletics began to chip away.

Oakland got on the board in the fourth inning. Brian Serven's RBI single cut the deficit to 2-1. Then in the fifth, the Athletics took the lead for good. Jonah Heim's two-run single put Oakland ahead 3-2. Tyler Soderstrom followed with a solo home run in the same inning, extending the lead to 4-2. Bennett was pulled with one out in the sixth, having allowed four runs on five hits over 5 1/3 innings. He struck out four and walked two.

The Athletics added more insurance in the sixth. Henry Bolte led off with a solo homer off reliever Justin Slaten. Later, Donovan Walton, pinch-hitting, ripped a ground-rule double into Boston's bullpen, scoring two more runs. That made it 7-2. The Red Sox managed one run in the bottom of the sixth on a sacrifice fly, but that was all they could muster.

Oakland's bullpen, which entered the game with the highest ERA in the majors at 5.64, stepped up. Relievers combined to allow just one run over the final three innings. Hogan Harris got the last four outs, striking out two, to earn his 10th save of the season.

Boston's offense struggled to generate much after the first inning. Willson Contreras, returning to the lineup after missing two games with an illness, went 0-for-4. He was booed by the home crowd after jogging lightly on a groundout in the eighth inning, a sign of frustration from fans who expected more urgency.

Defensively, the Athletics had a historic moment. Shortstop Jacob Wilson played errorless baseball for the 110th consecutive game at his position, matching the MLB record set by the Baltimore Orioles' Mike Bordick in 2002. Wilson's streak has been a bright spot for Oakland in an otherwise difficult season.

For the Red Sox, the loss was a missed opportunity. They had won nine straight games and were looking to become the first team in franchise history to achieve two separate double-digit winning streaks in the same year. Instead, they will have to regroup and try to start a new streak on Sunday.

Up next, the Athletics will send right-hander J.T. Ginn (8-6, 3.51 ERA) to the mound. The Red Sox have not yet announced a starter for the series finale. The game is scheduled for 1:35 p.m. at Fenway Park.
