Ezequiel Tovar delivered a walk-off single in the 12th inning, leading the Colorado Rockies to a 9-8 victory over the Boston Red Sox, marking Boston's fourth consecutive loss since the All-Star break. The game was tied after Jake Cave's single scored Brendan Rodgers, setting the stage for Tovar's decisive hit. Tovar extended his hitting streak to nine games, while Charlie Blackmon contributed with two hits, including his seventh home run. Boston struggled at crucial moments, grounding into three double plays and playing without closer Kenley Jansen due to health issues related to Denver's altitude. The Red Sox's Tanner Houck allowed four runs over six innings, despite having a strong season prior. The Rockies capitalized on a four-run third inning to secure their fourth win in five games.
