There was a big upset in college basketball Tuesday night.
No. 5 San Diego St. took a 20-game winning streak into Laramie, Wyoming before being upset by the Wyoming Cowboys 68-62. San Diego State drops to 21-2 overall and 10-1 in conference play.
Meanwhile, fourth-ranked Wichita State had a 78-67 win over Southern Illinois. Ron Baker scored 19 points.
That leaves Wichita State and Syracuse as the only remaining unbeaten teams. No team has had a perfect regular season since Saint Joseph's in 2004.
