Rotnei Clarke led five players in doubles figures with 14 points in Butler's 69-58 win over La Salle in the Atlantic 10 quarterfinals Friday, and now the Explorers must await their NCAA tournament fate.
Khyle Marshall had 13 points, and Andrew Smith added 11 points and eight rebounds for the fifth-seeded Bulldogs, who face regular-season champ Saint Louis in Saturday's semifinals.
Clinging to a one-point lead early in the second half, Butler went to work inside. Smith scored in the paint, Marshall had a dunk, and Kameron Woods completed a three-point play after a putback.
The 11-2 run gave the Bulldogs (26-7) a double-digit lead, and they held off fourth-seeded La Salle (21-9) the rest of the way.
Tyreek Duren led the Explorers with 19 points on 8-of-13 shooting.
