The second annual Pac-12 Baseball Tournament returns to Scottsdale Stadium on May 23-27, 2023. In a change from the 2022 tournament, the 2023 Pac-12 Baseball Tournament expands the field from eight to nine teams and switches to pool play. Pool play will take place on Tuesday, Wednesday, and Thursday, with three games per day. Each pool will play a round-robin. The three pool winners and one Wild Card team will advance to the Friday single-elimination semifinals. The best record of the non-advancing teams will determine the Wild Card. Any tiebreaker will be awarded to the highest-seeded team.
