On Saturday (The Semifinals) of the ACC Baseball Tournament, the match-up between the four remaining teams is determined by previous opponents. If teams have played previously in the tournament, every attempt will be made to avoid a repeat match-up between teams, regardless of seed. If it is impossible to avoid a match-up that already occurred, then the determination is based on avoiding the most recent, current tournament match-up, regardless of seed. If no match-ups have occurred, the team left in the winners bracket will play the lowest seeded team from the losers bracket.
