OMAHA, Neb. — Derrick Marks scored a career-high 35 points, including 18 straight in the second half, and Boise State upset No. 11 Creighton 83-70 on Wednesday night.
The Broncos (5-1), who played No. 13 Michigan State within four points on the road last week, beat a ranked opponent for the first time in four seasons and on the road for the first time since March 2005.
Creighton (6-1) hadn't lost a regular-season November home game since 1989.
Anthony Drmic had 17 points and Jeff Elorriaga added 12 for the Broncos.
Doug McDermott led Creighton with 21 points and Grant Gibbs added a season-high 17.
Boise State led 39-33 after shooting 64 percent from the field in the first half. The Broncos made seven straight 3-pointers and were 9 of 13 from beyond the arc in the first 20 minutes, with Elorriaga making 4 of 5.
Creighton got within five points in the last 3 minutes, but Drmic scored twice and Marks made four free throws to seal the Broncos' first win over a ranked opponent since they beat Utah State in February 2009.
The Broncos had come into the game having lost 18 of 19 on the road against ranked teams, with the lone win against Nevada in March 2005.
Marks, who had 24 points against Michigan State last week, scored 28 points in the second half to keep the Bluejays at bay.
After Drmic scored with 14:32 left, Marks took over.
He scored the next eight field goals and made a couple of free throws for the Broncos, using a mix of penetrating moves to the basket, pull-up jumpers and runners.
No one else for Boise State scored against until Drmic's basket with 4:59 left made it 73-59.
Marks was 13 of 19 for the game, 10 of 15 in the second half. His performance allowed the Broncos to keep leads of 8 to 12 points until Creighton made its late run.
Creighton came in with all six of its wins by double figures, and the Bluejays were impressive in weekend wins over Wisconsin and Arizona State in Las Vegas.
Boise State was better from start to finish Wednesday against the highest ranked opponent it had faced since playing No. 9 Washington State in November 2007.
McDermott, who scored 30 points against Wisconsin and 29 against Arizona State, made 7 of 11 shots, including 4 of 5 3-pointers. Gibbs' 17 points were a season high.
But Gregory Echenique, the Bluejays' strong man inside, managed only nine points and three rebounds. Ethan Wragge, who had been shooting 58 percent from 3-point range, was 1 of 5 from beyond the arc.
Every time the Bluejays looked ready to make runs in the first half, Elorriaga thwarted them with timely 3s.
Echenique's 12-foot baseline jumper as the shot clock was about to expire and Jahenns Manigat's 3 pulled the Bluejays to 27-23, but Elorriaga let fly a long shot and quieted the crowd.
McDermott's 3 and Echenique's layin off Austin Chatman's steal got the Bluejays back within four points, but Elorriaga connected again and the Broncos were on their way to building an 11-point lead before Creighton chiseled it back to six.
