2013 West Coast Conference baseball tournament
The 2013 West Coast Conference baseball tournament was held from May 23 through 25 at Banner Island Ballpark in Stockton, California. It was the first postseason championship event sponsored by the West Coast Conference since 2009, the first such event to be held at a neutral site, and the first to feature more than two teams. In the championship game, San Diego defeated San Francisco, 2–0, to win its first tournament championship. As a result, San Diego earned the league's automatic bid to the 2013 NCAA Division I baseball tournament.
