Fernando Tatis Jr. led the San Diego Padres to a 6-5 victory over the Detroit Tigers with a walk-off single in the 10th inning, marking his first career walk-off hit. Tatis, who had been sidelined since June 22 due to a stress reaction in his thighbone, returned to action and capitalized on an intentional walk to Luis Arraez. Yu Darvish also made his first start since May 29, allowing three runs over 2 2/3 innings after recovering from multiple injuries. The win solidified the Padres' half-game lead over the Arizona Diamondbacks for the National League's first wild-card spot. Jackson Merrill played a pivotal role with a three-run homer, nearly hitting for the cycle, as the Padres overcame a 5-0 deficit. The victory also moved San Diego within 4 1/2 games of the Los Angeles Dodgers in the NL West standings.
