SIOUX FALLS, S.D. -- Joe Rosga banked in an off-balance 3-pointer with 3.2 seconds left in regulation and Denver held off Oral Roberts for a 90-88 victory on Sunday night in the second double-overtime game in Summit League Tournament history.

Freshman R.J. Fuqua made two free throws to give Oral Roberts a 68-65 lead, but Rosga quickly drove to the basket, was fouled at 11.3 and made two at the line. Austin Ruder made it a three-point lead again but Rosga took a handoff at the 3-point arc and his 3 hit the corner of the backboard and went through the net.

Denver forward Jake Krafka went 1 of 2 at the line with 21 seconds left in the second OT and the Pioneers didn't get off a final shot after losing control of it in the lane.

Third-seeded Denver (15-14) will play No. 2 seed South Dakota in the semifinals on Monday.

Daniel Amigo had his sixth double-double of the season with 22 points and 11 rebounds for Denver. Ade Murkey had a career-high 20 points, eight rebounds and seven assists. Rosga finished with 18 points and four 3-pointers.

Emmanuel Nzekwesi and Ruder each scored 20 points for six-seeded Oral Roberts (11-21).
