PORTLAND, Ore. (AP) Gary Payton II says having his famous dad sitting courtside doesn't make him nervous.
''No, not at all,'' Payton said. ''I can look over and he can give me some pointers if I'm doing something wrong, so it's helpful.''
The younger Payton overcame a cold start shooting and finished with 12 points and 12 rebounds in a physical 65-58 overtime victory over the Portland Pilots on Saturday night.
Payton hit a jumper that put Oregon State up 59-57 with 2:12 left in the extra period. Portland's Thomas van der Mars missed the first of two free throws with 1:08 to go, and Oregon State's Jarmal Reid added a key block to keep the Beavers in front.
Olaf Schaftenaar and Payton added free throws to stretch the Beavers' lead to 63-58 and the Pilots couldn't catch up.
Victor Robbins led all scorers with 18 points for the Beavers (5-2), who won their second straight.
The Beavers trailed 30-24 at the half and shot just over 27 percent for the game. But they toughed out the win with defense, holding the Pilots to just over 27 percent shooting from the floor.
''For us it seemed like we just came out of a two-week road trip. Mentally we were drained for some reason,'' said Oregon State coach Wayne Tinkle. ''So we've got to answer that. But I tell you what, what a huge test. So proud of our guys for battling through all of that and finding a way.''
Bobby Sharp was the top scorer for the Pilots (6-2) with 12 as one of just two players in double figures.
After trailing by as many as seven points earlier in the second half, Oregon State pulled ahead 45-44 on Langston Morris-Walker's layup with 6:55 left. He padded the lead with a jumper, but Sharp hit a 3-pointer to tie it at 47 with 5:04 left.
The teams wrestled for the lead the rest of the way. Robbins made a pair of layups to put the Beavers in front, but Alec Wintering's layup with 28 seconds to go tied it at 53 and sent it to overtime.
The Pilots were without their top scorer, guard Kevin Bailey, because of an injured left foot. Bailey was averaging 13.1 points. He was injured in Portland's 83-71 victory Wednesday over crosstown rival Portland State.
''Give them credit. They're very good blocking shots. Their length and athleticism bothered us,'' Pilots coach Eric Reveno said about the Beavers. ''And it's the fifth game in eight days for us.''
Oregon State is playing their first season under Tinkle, who spent the previous eight seasons at Montana, where he led the Grizzlies to Big Sky championships in 2012 and 2013.
Payton, a transfer from Salt Lake Community College, is the son of Beavers great Gary Payton, who went on to become a nine-time NBA star known for his 13 seasons with the Seattle SuperSonics.
The elder Payton watched his son from a courtside seat, posing for pictures with fans during the half.
Both teams got off to a slow start. The Pilots didn't get a field goal until Jason Todd's 3-pointer more than five minutes into the game.
Payton didn't take his first shot until he made a layup to close the Beavers within 27-24 with 1:24 left in the half. The Pilots answered with Sharp's 3-pointer and Portland led 30-24 at the half.
Payton had eight rebounds in the first half to help overcome his lack of shooting.
Van Der Mars' layup gave the Pilots a 33-26 lead, their biggest in regulation.
Oregon State: The Beavers prior losses came to Oklahoma State and Auburn at the MGM Grand Main Event in Las Vegas. ... In addition to Gary Payton, former Beaver Charlie Sitton (1980-84) was also at the game.
Portland: The Pilots lone loss of the season came to Valparaiso in Nashville's Challenge in Music City.
It was Gary Payton II's third straight game with double-digit rebounds; over that span he's averaging 13.3.
Portland's Kevin Bailey has a strained tendon, and he'll be revalued in a week. When asked if the Pilots missed him, coach Eric Reveno said: ''I think we definitely did, his athleticism and ability to create offensively, he just bails us out sometimes.''
The Beavers host Mississippi State on Dec. 13.
