Swihart’s double in 13th lifts Boston over Phillies

Blake Swihart doubled into the Red Sox bullpen to score Eduardo Nunez in the 13th inning and Boston beat the Philadelphia Phillies 2-1 on Monday night in Boston to move a season-high six games ahead of the New York Yankees in the AL East.

Hector Velazquez (7-0) pitched a scoreless inning for the win and Austin Davis (11) took the loss after pitching a perfect 12th before allowing Nunez’s leadoff single in the next inning. Luis Garcia, the 12th pitcher of the night, struck out Brock Holt but allowed Nunez to steal second.

Swihart lined the first pitch he saw toward the gap and into the bullpen on one hop for his first career walk-off RBI.

The Red Sox have won 19 of their last 23 games and matched their biggest lead in the division of the season. At 75-33, they have the best record in baseball and are 42 games above .500 for the first time since the end of the 1946 season.

MARINERS 2, ASTROS 0 >> James Paxton (9-4) excelled in his return from the disabled list, Nelson Cruz had a two-run double in the sixth inning, and host Seattle beat Houston. Astros starter Gerrit Cole (10-3) carried a no-hitter into the sixth, but Jean Segura ended it with a two-out infield single. Two batters later, Cruz lined his double down the left-field line. BRAVES 5, MARLINS 3 >> Freddie Freeman hit a go-ahead homer in the third inning, Ronald Acuna Jr. also went deep and host Atlanta beat Miami. The Braves are now a half-game behind first-place Philadelphia in the NL East.

CARDINALS 5, ROCKIES 4 (10 INNINGS) >> Marcell Ozuna hit his first career game-ending homer in the 10th inning, and host St. Louis snapped Colorado’s fourgame win streak. Ozuna connected against Jake McGee (14), sending a one-out drive deep to center for his 13th homer.
