PROVIDENCE, R.I. — Weyinmi Efejuku scored 16 and Providence upset No. 1 Pittsburgh 81-73 on Tuesday night for its first win over a top-ranked team in 33 years.

Sharaud Curry added 15 points for the Friars (17-11, 9-7 Big East), who picked up a big victory for their NCAA tournament hopes.

DeJuan Blair fouled out on a moving pick with 46 seconds left as Pittsburgh (25-3, 12-3) tried to rally.

Blair, the reigning Big East player of the week, averaged 21 points and 20.5 rebounds in wins over No. 1 Connecticut and DePaul that elevated the Panthers to the top spot on Monday. But he picked up two quick fouls — his third and fourth — midway through the second half.

He finished with 17 points and eight rebounds.
