NEW YORK -- Rick Porcello just finished watching his Boston Red Sox teammates score six times in a span of 22 minutes off New York Yankees starter Michael Pineda.

The right-hander nearly gave it all back but after a visit from pitching coach Carl Willis, but he rebounded to finish strong.

Aided by catcher Blake Swihart's first career multi-homer game, Porcello pitched eight innings and the Red Sox extended their winning streak to a season-high five games and prevented the Yankees from inching closer to a clinching a playoff spot with a 10-4 victory Tuesday night.

"Sometimes you need a kick in the butt," Porcello said after allowing four runs and six hits in a 118-pitch outing. "I didn't feel like I was sleepwalking out there but our offense goes out there and grind out six runs in the first inning, the last thing you want to do is give four back. So that mound visit kind of locked me back in."

Before Willis visited Porcello, Swihart hit a three-run home run to cap Boston's first six-run inning in New York since Sept. 26, 1989, according to the Elias Sports Bureau. Swihart's first home run off Pineda's 2-2 fastball came after the Red Sox scored on a groundout by shortstop Xander Bogaerts, a fielder's choice by first baseman Travis Shaw and a double by right fielder Brock Holt.

Porcello (9-14) quickly gave it back, opening his final start of the season by allowing a RBI double to right fielder Carlos Beltran following a run-scoring groundout by catcher Brian McCann. After a 2-2 fastball turned into second baseman Dustin Ackley's two-run home run, Willis paid a visit and four pitches later, Porcello escaped.

"I don't think it was a long first inning," Porcello said. "I just went out there and made some mistakes really with my fastball. In warmups and everything I felt fine, I was locating the ball fine. Kind of after Carl came out and woke me up a little bit, he told me to make some adjustments, get the ball down and stop making mistakes."

Porcello finished his first season in Boston with a 9-14 record and a 5.02 ERA. He won five of his final eight starts after missing a month with a strained right triceps and finished his outing by allowing five baserunners the rest of the night.

"He made some really good adjustments, started to work a changeup in the mix and a curveball when he needed it," Boston interim manager Torey Lovullo said. "A lot of credit goes out to Rick for rebounding and working as free and easy as he did and giving us eight solid innings."

The Red Sox added to their big inning with a solo home run by center fielder Mookie Betts on the first pitch of the fifth after Porcello retired Yankees center fielder Jacoby Ellsbury on a warning track fly ball with two on in the fourth.

Swihart hit his second home run with two outs in the eighth off Bryan Mitchell and the 23-year-old became the youngest Red Sox catcher to get a multi-homer game since Mike Ryan on May 2, 1965. Boston's final run came on a run-scoring groundout by Josh Rutledge, who entered in the eighth for designated David Ortiz.

"We were just putting good swings on some good balls and just trying to go out there and do everything we can," Swihart said. "We're still playing for each other and going out there and having fun."

While the Red Sox won for the eighth time in 11 games and 16th time in their last 24, the Yankees (86-71) were unable to recover from Pineda's poor start. Pineda (12-9) fell behind 6-0 just 24 pitches in and wound up allowing seven runs and seven hits over six innings.

"It just looked like his stuff was up and was flat," Yankees manager Joe Girardi said. "He seemed to find it after that. They jumped all over him. He was up."

New York's offense sputtered after getting four runs. Designated hitter Alex Rodriguez went 0-for-4 with two strikeouts and heard some boos after striking out in the eighth.

"There's not alarm. Let's make it clear," Rodriguez said. "That team is playing really good baseball. That's a different team than we saw all spring and summer so give those guys credit. They're playing hard. I like our team a lot. I like where we're at. We just need to relax and play our game."

After Tuesday's games, the Yankees lead the Los Angeles Angels by three games for the first American League wild card. The Houston Astros slipped a half-game behind the Angels.

With New York's loss, Toronto clinched no worse than a tie for the AL East title. The Blue Jays lead the Yankees by 5 1/2 games.

NOTES: 2B Stephen Drew underwent additional testing for a possible concussion, but the Yankees did not have the results. After the game, Drew sounded convinced he might have one, saying: "In the long run that's kind of like the symptoms I'm having. It's headed that way. I can't explain it." Drew has not started since Sept. 15 due to a head cold and his place on the postseason roster may be in doubt.. ... Boston manager Torey Lovullo met and took a picture with President Obama, who is staying in the same Manhattan hotel while attending the UN General Assembly. "It was a very exciting moment for me," Lovullo said. "It couldn't have been more at ease." ... Boston RHP Clay Buchholz (elbow) did a long-toss session Tuesday and will throw a bullpen session in one of the next two days. ... New York manager Joe Girardi said backup C John Ryan Murphy was taking ground balls at first base and could see time there with the team's recent struggles against left-handers.
