TEMPE, Ariz. – Jermaine Marshall scored eight of his 29 points in the second overtime and Jordan Bachynski blocked T.J. McConnell’s layup attempt in the waning seconds, sending Arizona State to a 69-66 victory over second-ranked Arizona on Friday night.

With both teams struggling offensively for most of the night, Arizona State (19-6 overall, 8-4 Pac-12) turned to Marshall when it counted. The transfer from Penn State went more than 20 minutes without a field goal, but made consecutive three-pointers and scored on a drive with 14 seconds left to put the Sun Devils ahead 67-66 in the second overtime.

McConnell tried to drive the lane, but 7-foot-2 senior Bachynski swatted his shot away, leading to Jahii Carson’s breakaway dunk.

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 of Arizona missed a three-point shot at the buzzer.

“No words can explain the joy that we feel right now,” Bachynski said.

McConnell led Arizona (23-2, 10-2) with 17 points and added five rebounds. Kaleb Tarczewski had 13 points and 13 rebounds, and Aaron Gordon had 13 points and 10 rebounds for the Wildcats, who shot 35 percent and went 4 of 14 from three-point range.

Arizona was 16 of 30 on free throws.

“Our offense is continuing to put more and more pressure on our defense,” Arizona coach Sean Miller said. “You can only guard so well.”

Carson finished with 17 points and six assists. Bachynski had 13 points, seven rebounds and blocked eight shots.

Arizona, which was listed as a 5½-point favorite, remains in first place in the Pac-12.

Arizona State is in third place, a half-game behind UCLA.

Arizona turned the first desert rivalry game into a rout, racing away from the Sun Devils for a 91-68 victory in Tucson on Jan. 16.

Arizona lost one of its best players in its only previous setback when forward Brandon Ashley injured his right foot against California two weeks ago.

Arizona State has won six of its last seven games to get back into the NCAA tournament picture.
