Dipsy Selolwane, the nation’s leading goal scorer, scored just 33 seconds into Sunday’s Conference USA Tournament championship match, and Saint Louis rode that momentum to a 2-0 victory over sixth-seeded Marquette at USF Soccer Stadium. This is the second straight tournament title for the 16-1 Billikens, and their third in the last five years. Marquette, which upended the second seed (UAB) and third seed (South Florida) to advance to its first title match since 1996, drops to 12-8-1.
