J.D. Martinez hit his 40th homer and drove in four for Boston, which snapped Houston’s seven-game winning streak even after the Astros rallied with a four-run sixth inning to tie the game at 5.

The East-leading Red Sox sliced their magic number to 11 for their third straight division title. Boston leads the second-place Yankees by 8 ½ games after they lost at Seattle.

Jose Altuve and Marwin Gonzalez each hit a solo homer for the West-leading Astros, who saw their lead over Oakland cut to 2 1/2 games. The Athletics beat Texas earlier in the day.

With runners on first and second, Moreland blooped a single to left against Hector Rondon (2-3), and pinch-runner Tzu-Wei Lin raced home easily. Gonzalez tried to barehand the ball in left field for a quick throw but lost his grip and let it dribble toward the Green Monster.

Craig Kimbrel (5-1) pitched a perfect ninth to preserve a tie.

Trailing 5-1 in the sixth, the Astros rallied against starter Rick Porcello and Boston’s recently struggling bullpen. Altuve led off with a shot over the Monster, Tyler White had a two-run double off Heath Hembree, and Josh Reddick hit a tying double off Brian Johnson.

Boston had built its lead on Martinez’s three-run shot an inning earlier. Martinez’s sacrifice fly had pushed Boston ahead 2-1 in the third.

The Red Sox loaded the bases with one out in the eighth inning, but reliever Tony Sipp entered and struck out pinch-hitters Blake Swihart and Christian Vazquez.

Porcello gave up four runs in 5 2/3 innings. Astros starter Dallas Keuchel allowed five in six innings.

LONG WAIT

There was a 3-minute, 50-second review of a key play at the plate where Red Sox catcher Sandy Leon jumped for a throw from shortstop Xander Bogaerts to get Altuve in the seventh. He was called out, and replays were inconclusive on if the tag was applied before he touched the plate with his left hand.

CLUB MILESTONE

Martinez became just the fourth Red Sox player to hit 40 homers in his first season with the team.

Dick Stuart had 42 in 1963, Jimmie Foxx 41 in ’36 and Manny Ramirez hit 41 in 2011.

HOUSTON INVASION

There was a large contingent of Astros fans wearing old and new-style team jerseys all weekend, filling Fenway Park, restaurants and bars in the area. The Houston Texans faced the New England Patriots about 45 minutes away in Foxborough, Massachusetts, earlier in the day.

TRAINER’S ROOM

Red Sox: Lefty Chris Sale is still set to be activated off the disabled list and start Tuesday. Manager Alex Cora said the plan is for the ace to go about two innings the first time as he gradually works back from mild left shoulder inflammation that landed him on the DL twice in less than three weeks.

UP NEXT

Astros: RHP Justin Verlander (14-9, 2.73 ERA) is scheduled to pitch in Detroit on Monday for the first time since being traded last season by the Tigers. LHP Francisco Liriano (4-9, 4.90) is slated to start for the Tigers.

Red Sox: After an off day, Sale (12-4, 1.97) is set to face Toronto LHP Ryan Borucki (3-4, 4.39) when the teams open a three-game series Tuesday at Fenway.
