In the opening game of the 2026 Vedder Cup, the Seattle Mariners fell to the San Diego Padres by a score of 4-1. Starting pitcher Bryan Woo delivered a solid performance, going seven innings and allowing three runs on eight hits. However, his struggles in the third inning proved costly, as he failed to throw first-pitch strikes effectively, allowing the Padres to capitalize and score three runs. The Mariners managed to load the bases in the second inning but could only produce a sacrifice fly from Dominic Canzone. Despite showing some offensive promise, including two hits from Randy Arozarena and two walks from Julio Rodríguez, the Mariners could not break through against the Padres' pitching staff. The loss highlights ongoing challenges for the Mariners' offense as they seek to improve in the upcoming games.
