TEMPE, Ariz. (AP) -- Arizona State almost let one get away on an historic night for its shot blocker and an important night to get back on track.
Jermaine Marshall scored 25 points, including seven in overtime, as Arizona State held off Oregon State 86-82 on Thursday night.
That was despite 24 points by Pac-12 scoring leader Roberto Nelson - just in the second half and overtime.
He certainly got Arizona State coach Herb Sendek's attention.
"As long as Roberto Nelson is on the floor, making the kinds of shots he can make, almost indefensible, the game is never over," Sendek said. "We were trying everything we could. He really is an amazing player."
Jahii Carson added 23 points, six rebounds and six assists for the Sun Devils (17-6, 6-4 Pac-12), who had a chance to win at the end of regulation, then took the lead for good halfway through overtime.
The Sun Devils also missed 15 free throws, including four in the overtime to make it interesting.
Nelson had 26 points to lead the Beavers (13-9, 5-5) and scored with 19 seconds left in regulation to force overtime.
Jordan Bachynski added 17 points, 15 rebounds and seven blocked shots for the Sun Devils, who won their fourth in the last five games.
With seven blocks on Thursday, Bachynski has 279 in his career, passing Arizona's Anthony Cook for the conference career record of 278.
"It's huge," Bachynski said. "I'm honored that I can hold that title. But you also have to think about guys in the `60s like Bill Walton. I'm sure he had more blocked shots than I did, but they didn't have that stat back then. It is because of guys like him that they laid the foundation so that I can hold this record."
In overtime, Jonathan Gilling hit a 3-pointer - his first basket of the game - with 2:48 left and scored six straight to take a 78-72 lead with 1:27 left. Nelson hit a 3-pointer with three seconds left to get Oregon State within 84-82. Marshall made two free throws with 1.1 seconds left for the final margin.
"Our guys did not back down," Oregon State coach Craig Robinson said. "But we didn't make enough good plays."
After Arizona State opened up a seven-point lead midway through the second half, Oregon State ran off six straight points, the last four from Devon Collier underneath to tie it at 55 with 5:48 remaining. The Beavers got within 63-62 but failed to score on three straight possessions.
However, Marshall missed one of two free throws with 27.8 seconds left and Nelson drove for a layup with 19.7 seconds to tie it at 64. Carson missed a jumper with two seconds left and the game went to overtime.
"We had too many turnovers (15) and they got points off those turnovers (19)," Robinson said. "We have been able to sort of counter the many turnovers that we have gotten by not letting them score when we turn it over but today it was tough, a lot of those came from the foul line."
Oregon State opened up a 28-21 lead in the first half as the Sun Devils missed 16 of their first 22 shots.
Arizona State improved to 12-1 at home, while Oregon State fell to 2-6 on the road.
Nelson, averaging 21.8 points a game, was held to two points in first half, on 1-for-3 shooting over 10 minutes. He picked up two fouls and sat for the latter part of the half.
Oregon State held a 29-26 advantage at the break.
