The extreme heat sweeping the U.S. had serious consequences for players during weekend games. Cincinnati Reds shortstop Elly De La Cruz vomited on the field mid-game against the St. Louis Cardinals but remarkably continued to play, even hitting a two-run homer. In contrast, Seattle Mariners reliever Trent Thornton experienced a heat-related illness and had to be assisted off the field during their match against the Chicago Cubs. Both teams faced soaring temperatures of 92 and 94 degrees, respectively, prompting safety measures. Umpire Chad Whitson also suffered from dehydration and was treated in the dugout.

As temperatures climbed, the heat proved to be a significant health risk for both players and staff. The Cubs addressed the situation by setting up cooling stations for fans, while the Mariners adjusted their lineup to manage the reduced number of umpires. The athleticism displayed by De La Cruz amid discomfort showcases the resilience athletes display, yet it raises concerns about player safety under extreme conditions.
