The Trojans, who entered the game with a 24-1 record, struggled against Oregon State as their pitching failed to contain the Beavers' offense. USC was missing its top two starters, Mason Edwards and Grant Govel, who both pitched over the weekend.
Despite the setback, the Trojans remain in strong position overall with a 24-2 record. They will look to bounce back when they visit Maryland for a three-game series this weekend.
