BOSTON — J.D. Martinez thought about the possibility Sunday could be his final game for the Boston Red Sox at Fenway Park.

“I’m not, like blind,” “he said. “I know what’s going on.”

Martinez, Xander Bogaerts and Christian Vazquez had RBI doubles that helped slumping Boston to a 7-2 win on Sunday over the Milwaukee Brewers. All three could be in their final season with the Red Sox, who have just four wins in 17 games as Tuesday’s trade deadline approaches.

“I’ve been in this situation before. No point in stressing out about it,” Martinez said.

Martinez and Vazquez are eligible for free agency and Bogaerts can opt out of his contract.

“Memories,” Martinez said of what it meant to be wearing a Red Sox hat with a “B” on the front. “A first-class organization. I look at it and I think about winning”

Vazquez has played his entire career in Boston’s organization.

“We’re still here,” he said. “We can control what we can control. We’re here fighting together. … We’ll see what happens the next couple of days. We’re still here with this uniform and I hope we can stay here.”

Boston, which had a season-high eight doubles, was 3-7 on a season-long homestand and 8-19 in July.

Ex Red Sox outfielder Hunter Renfroe hit a two-run homer over the Green Monster for the second straight day and went 4 for 4 for NL Central-leading Milwaukee, which lost for only the second time in nine games since the All-Star break.

“We had a chance to expand the lead,” Brewers Manager Craig Counsell said. “It’s two-out-of-three and move onto the next series.”

Josh Winckowski (4-5) allowed two runs and seven hits in five innings, becoming Boston’s first starter to win in 30 games – the majors’ longest streak since the Mariners went 33 games in 1979.

Trailing 2-0, Boston struck with five unearned runs in the fifth against Aaron Ashby (2-9) on consecutive two-out RBI doubles by Bogaerts, Martinez, Vazquez and Alex Verdugo. Bogaerts drove in two runs with a drive down the left-field line. Verdugo’s hit was off Hoby Milner.

The inning was extended because second baseman Kolten Wong dropped shortstop Willy Adames’ throw on an attempted force play.

“It’s a tough catch, it’s a player on the run making a 50-foot throw and it’s just kind at your ankles,” Counsell said. “Tough play, hope to make it.”

The Red Sox added two more runs in the sixth when Jackie Bradley Jr. had an RBI double and scored on Jaylin Davis’ single.

Renfroe hit his 19th homer. He hit 31 last year in his only season with Boston and was dealt to the Brewers in November.

NOTES: Reliever Garrett Whitlock got hit off the back of the right leg on a grounder from Luis Urias but remained in after throwing a few warm-ups. Manager Alex Cora said All-Star 3B Rafael Devers (injured list, right hamstring) is expected to be in the lineup Tuesday.
