BOSTON — Mitch Moreland hit a three-run home run, Rafael Devers and Andrew Benintendi each added a solo homer, and the Boston Red Sox moved above .500 for the first time this season with a 14-1 victory over the Seattle Mariners on Friday night.
Boston (20-19) has won nine of 11, scoring 80 runs during the stretch. Seattle (20-21) lost for the 10th time in 12 games and is under .500 for the first time since the end of the 2017 season.
Eduardo Rodriguez (4-2) pitched seven scoreless innings, allowing five hits and striking out five to pick up his third win in four starts. It was the first time Rodriguez lasted seven innings in a start since Sept. 23, 2017, at Cincinnati.
Rookie Erik Swanson (1-4) took the loss, allowing seven hits and seven runs over 4⅔ innings.
It marked the latest rough outing for a Mariners’ pitching staff that has given up 11 or more runs four times in 12 games.
The Red Sox did the brunt of their damage in the third inning.
Jackie Bradley Jr. led off with a double down the left field line and scored on Mookie Betts’ two-out single up the middle.
J.D. Martinez moved Betts over to third base with a single, and Moreland cleared the bases with his looping blast that landed just over Boston’s bullpen in center. It was Moreland’s 11th home run of the season.
Devers led off the fourth inning with a line-drive homer over the Mariners’ bullpen in right field.
Moreland added an RBI double in the fifth.
Boston scored in all but two innings.
Red Sox: Manager Alex Cora said left-hander David Price (left elbow tendinitis) continues to throw, “feels a lot better” and “seems like he’s in a good place.” The plan is for him to get in a few bullpen sessions before a decision is made on his next step. … Cora said he texted with 2B Dustin Pedroia (left knee irritation), who is travelling with Double-A Portland. Cora said next for Pedroia is to see how he reacts to playing three straight games. … Utility man Brock Holt (scratched cornea) was with the team Friday and could soon begin a rehab assignment.
Cora said there was no uneasiness in the clubhouse a day after several members of the team decided not to attend a celebration at the White House for Boston’s World Series championship.
“That’s the route we decided, and we respect everything and we’re fine with it. Back to baseball today,” Cora said. “In my world, I decided not to go for my reasons. I know the government has helped. We still have a long way to go. That’s our reality.”
Red Sox: Rick Porcello (2-3, 5.11 ERA) is 2-0 with a 2.45 ERA in his last four starts. He has held opponents to a .202 batting average with 25 strikeouts during that stretch.
