Durham, n.c. — Freshman Dennis Smith Jr. scored a season-high 32 points to help North Carolina State rally from 12 down late in the first half and stun No. 17 Duke, 84-82, on Monday night.

Kimball Union Academy graduate Abdul-Malik Abu added 19 points for the Wolfpack (14-7, 3-5 Atlantic Coast Conference), who earned the program’s first win at Duke’s famously hostile Cameron Indoor Stadium since 1995.

No. 3 Gonzaga 83, Portland 64

Portland, Ore. — Zach Collins had 13 points and No. 3 Gonzaga remained the nation’s only undefeated Division I team with a victory over Portland in a game that was rescheduled because of a winter storm earlier this month.

The Bulldogs have won 20 straight games, their longest streak since winning that many in the 2005-06 and 2003-04 seasons. Gonzaga is now 8-0 in West Coast Conference play.
