BOSTON — James Paxton worked 5 1/3 scoreless innings and five Boston pitchers combined for the seven-hit shutout as the Red Sox beat the Kansas City Royals 2-0 on Thursday night.

John Schreiber, Josh Winckowski and Chris Martin followed Paxton, and Kenley Jansen retired the side in order in the ninth inning for his 25th save as Boston moved five games over .500 at 60-55 and took 3 of 4 games from the Royals.

Alex Verdugo hit a sacrifice fly in the fourth inning to give Boston a 1-0 lead and Adam Duvall added an RBI double in the fifth.

Trevor Story doubled to straightaway center in the fourth for his first hit in nine at-bats since returning from the injured list.

In the fifth inning as rain fell at Fenway Park, Duvall’s hit was originally ruled a foul ball by third-base umpire Emil Jimenez. But Boston Manager Alex Cora’ decided to challenge the call and it was overturned following a review.

Paxton (7-3), who allowed three homers in his previous start against Toronto, scattered six hits with six strikeouts and no walks. The 34-year-old left-hander was helped by a sliding catch by Verdugo that led to an inning-ending 9-3 double play in the second.

Austin Cox and Taylor Hearn worked the first three innings for Kanas City. Alec Marsh (0-6) went the final five innings, allowing two runs while striking out three.

The Red Sox improved to 9-1 this season wearing their yellow “City Connect” uniforms. Boston is 24-5 all time in the uniforms.

NOTES: Friday will mark Chris Sale’s first start for Boston since exiting his June 1 appearance with left shoulder inflammation. Before Thursday’s game, Cora says the plan is for Sale to pitch four innings. “Just to have him back, that’s huge for us,” Cora said. … INF Justin Turner (heel) wasn’t in the starting lineup for the third straight game. He has now missed six of the past nine games since the injury occurred on July 31. … Cora says there’s a good chance that RHP Garrett Whitlock (elbow) will be activated on Sunday. … RHP Tanner Houck (facial fracture) was supposed to make a second rehab outing for Triple-A Worcester on Thursday, but the game was rained out. He’s now scheduled to pitch for the WooSox on Friday.
