TEMPE, Ariz. – Jermaine Marshall scored eight of his 29 points in the second overtime and Jordan Bachynski blocked T.J. McConnell's layup attempt with 6 seconds left, sending Arizona State to a 69-66 victory over No. 2 Arizona on Friday night.

With both teams struggling offensively most of the night, Arizona State (19-6, 7-5 Pac-12) turned to Marshall when it counted. He went over 20 minutes without a field goal, but hit consecutive 3-pointers and scored on a drive with 14 seconds left to put the Sun Devils up 67-66.

McConnell then tried to drive the lane, but Bachynski swatted his shot away, leading to a breakaway dunk by Jahii Carson.

Arizona State's fans rushed the court, had to be cleared because there was 0.8 seconds left, then poured out of the stands again after Nick Johnson missed a 3-pointer at the buzzer.

McConnell led Arizona (23-2, 10-2) with 17 points and five rebounds.
