TORONTO — Carlos Narváez hit a two-run double in the sixth inning, Nathaniel Lowe had two RBI singles, and the Boston Red Sox beat the AL-leading Toronto Blue Jays 4-1 on Tuesday night.

The slumping Blue Jays had just three hits and lost for the fifth time in six games. Toronto began the day with a two-game lead over the Yankees in the AL East. New York closed to within a game by rallying to beat the White Sox, 3-2.

Masataka Yoshida had two hits and scored a run as the Red Sox improved to 40-39 on the road.

Justin Wilson (4-1) got four outs for the win and Aroldis Chapman finished for his 32nd save in 34 chances as the Red Sox boosted their wild-card hopes.

Narváez chased Toronto right-hander Kevin Gausman with a two-out hit in the sixth that put the Red Sox up 4-1.

Gausman (10-11) allowed four runs and nine hits in 5 2/3 innings. He walked one and struck out seven.

Boston’s Lucas Giolito allowed one run and three hits in 4 2/3 innings, failing to finish five innings for the second straight start. Giolito walked four and struck out three.

Key moment

Toronto’s George Springer thought he’d hit a two-run double in the second inning, but third-base umpire Scott Barry called Springer’s ground ball foul. On the next pitch, an irate Springer was called out looking to end the inning.

Key stat

Boston is 31-19 against the AL East and has won 23 of its last 32 against division foes.
