The Boston Red Sox, having struggled since the All-Star break, secured a much-needed series victory against the Seattle Mariners with a dramatic walk-off win. Rafael Devers was instrumental, delivering a decisive double in the 10th inning to clinch a 3-2 victory, marking Boston's first series win in four attempts. The game saw solid pitching performances from Brayan Bello and George Kirby, and notable contributions from newcomers Danny Jansen and Lucas Sims. Devers has been in exceptional form, going 14-for-27 with six doubles, a triple, and a home run in his last seven games, bringing his batting average above .300. His recent performances have also placed him among the top third basemen in career extra-base hits by age 27. The Red Sox hope to maintain this momentum as they continue to vie for a playoff spot.
