PITTSBURGH (AP) — Wilyer Abreu had three hits and drove in two runs and the Boston Red Sox beat the Pittsburgh Pirates 6-1 on Sunday to complete a three-game sweep.

Abreu’s RBI single off Martin Perez (1-1) in the third gave the Red Sox the lead for good. He added another RBI single in the sixth as Boston continued its strong play away from Fenway Park. Reese McGuire added a pinch-hit two-run single for the Red Sox, who improved to 10-3 on the road so far this season.

Boston bounced back after a bumpy homestand by keeping the Pirates in check yet again. Justin Slaten (1-0) worked two scoreless innings in relief to earn the victory as the Red Sox’s road ERA dropped to 1.45.

Perhaps just as importantly, Boston found a way to take care of the Pirates without third baseman Rafael Devers and outfielder Tyler O’Neill. O’Neill is on the injured list and Devers didn’t play in the series while nursing a bone bruise in his knee, forcing the Red Sox to rely even more on players such as the 24-year-old Abreu.

Asked how his team has responded despite having so many key players unavailable, manager Alex Cora just shrugged.

“Youth, to be honest with you,” he said. “They don’t know any better. Some of them, you know, they just show up every day, willing to work.”

Ke’Bryan Hayes had two of Pittsburgh’s seven hits and drove in the Pirates’ only run with a first-inning sacrifice fly. Pittsburgh has dropped six straight to fall to .500 (11-11) for the first time this season.
