PITTSBURGH -- — Mike Yastrzemski hit a game-sealing grand slam in the ninth inning, Matt Olson hit a first-inning home run while tying the franchise record for consecutive games played and the Atlanta Braves defeated the Pittsburgh Pirates 10-5 on Thursday. The Braves were leading 6-5 when Yastrzemski connected off Dennis Santana for his third career slam. Olson’s homer was a solo shot and his 25th season, opening the scoring. The first baseman played in his 740th straight game, going back to the start of the 2022 season, and tied the mark set by Dale Murphy from 1982-86.

Pittsburgh’s Bryan Reynolds and Esmerlyn Valdez hit back-to-back homers in the third to cut the Braves’ lead to 3-2. Jake Mangum had four hits and three RBI, including a two-run homer in the fourth that brought the Pirates to 6-4 and an RBI double in the sixth that made it a one-run game. Atlanta’s Bryce Elder allowed four runs in four innings. Mitch Keller (6-7) gave up three runs in three innings to fall to 1-5 with a 7.94 ERA in nine career starts against the Braves. Dylan Dodd (2-0) pitched a perfect fifth inning for the win. The game was delayed by rain for 35 minutes at the end of the fifth inning.
