The Houston Astros secured a 5-4 victory against the Boston Red Sox, with Yordan Alvarez hitting two home runs and rookie Spencer Arrighetti striking out a season-high 13 batters. Alvarez's performance at Fenway Park was notable, as he continues to dominate with a .463 batting average at the venue. The Red Sox attempted a comeback with solo homers from Danny Jansen and Masataka Yoshida, but fell short in the ninth inning as Josh Hader closed the game with his 25th save. Earlier in the week, the Astros also defeated the Red Sox 8-4, highlighted by a crucial two-run homer from Jose Altuve during a four-run seventh inning that turned the game. The Red Sox's bullpen struggled, allowing seven runs in the final three innings of both games. Despite the losses, Rafael Devers showcased his potential with a leadoff double in the ninth, but the team could not capitalize on the opportunity.
