ATLANTA (Interstat) — Austin Riley hit a three-run homer in the first inning, Grant Holmes pitched six scoreless innings and the Atlanta Braves routed the Boston Red Sox 8-1 on Sunday at Truist Park to win another series.

The first-place Braves took two of three from Boston for their 13th win in 15 series this season. They have only one series loss, along with a split of a four-game set.

Mike Yastrzemski also homered for Atlanta, which jumped ahead 5-0 through two innings against Brayan Bello, who suffered the loss on his 27th birthday.

Boston’s record dropped to 19-27, while Atlanta improved to 32-15.

The game was played before an announced crowd of 37,800 and lasted 2 hours, 33 minutes.

Atlanta struck first in the bottom of the first inning. After Drake Baldwin grounded out, Ozzie Albies singled to right field. Matt Olson walked, putting runners on first and second. Michael Harris II grounded into a force out, with Albies moving to third and Olson out at second. That brought Riley to the plate.

Boston had taken a brief 1-0 lead in the top of the first inning. Jarren Duran led off the game with a single to center field. Mickey Gasper struck out, and Wilyer Abreu grounded into a force out that erased Duran at second. Willson Contreras grounded out to end the inning with Abreu stranded on first. That run proved to be the only one Boston would manage until the ninth inning.

The Braves added two more runs in the second inning. Jorge Mateo led off with a double to left field. Mike Yastrzemski singled to shortstop, moving Mateo to third. Jose Azocar walked to load the bases. Baldwin then walked, forcing in Mateo to make it 4-0.

Harris II grounded out to second to end the inning with the Braves leading 5-0.

Holmes had little trouble through the middle innings. He allowed only a double to Duran in the third inning and a double to Contreras in the fourth, but both were stranded. Boston managed just two hits through the first five innings and did not advance a runner past second base.

Atlanta padded its lead in the fourth inning. Yastrzemski led off with a home run to right field, his second of the season, pushing the lead to 6-0. Azocar followed with a soft bunt single to third base. Baldwin flied out to left, and Albies flied out to left but Azocar advanced to second on the play.

Tyler Kinley relieved Holmes in the seventh inning. He allowed a single to Andruw Monasterio to lead off, but Connor Wong struck out, and Nick Sogard grounded into a force out that erased Monasterio at second. Duran grounded out to shortstop to end the inning. Kinley then worked a scoreless eighth inning, though he allowed two hits and one run with one strikeout.

Atlanta added its final run in the eighth inning. Mateo walked, and Yastrzemski walked to put runners on first and second. Azocar grounded into a force out, with the pitcher Ryan Watson fielding the ball and throwing to second for the first out. Mateo advanced to third on the play, with Yastrzemski out at second. Baldwin then hit a sacrifice fly to center field, scoring Mateo to make it 8-0.

Boston avoided the shutout in the ninth inning. Rafaela struck out looking to start the inning? Wait, the play-by-play shows the ninth inning began with Marcelo Mayer popping out to third in foul territory. Andruw Monasterio then popped out to first base. Connor Wong singled to right field. Nick Sogard doubled to right field, scoring Wong to make it 8-1. Duran struck out swinging to end the game.
