TUCSON, Ariz. (AP) — Kyle Fogg had 23 points and scored on a hard drive in overtime that nearly set off a brawl, lifting Arizona to a hard-fought 81-73 win over Oregon State on Thursday night.

Oregon State (11-6, 1-4 Pac-12) forced overtime after Ahmad Starks scored 10 of his 14 points in the final 3:16 of regulation. Arizona (12-5, 3-1) took control in overtime, going up six after a rebound slam by Nick Johnson and Fogg's drive with 1:15 left.

Fogg ran into Oregon State's Jared Cunningham while celebrating the basket, setting off a near melee that had players from both teams pushing each other and Wildcats coach Sean Miller shoving his players back to the bench.

Arizona's Kyryl Natyazhko and Oregon State's Joe Burton were ejected for leaving the bench. Fogg fouled out after being hit with a technical foul and Cunningham was also gone after getting personal and technical fouls.

Johnson finished with 19 points and Brendon Lavender scored 15 of his 18 in the second half, hitting five 3-pointers.

Cunningham had 22 points for Oregon State, which has lost four of five and has just one win at McKale Center since 1983, a span of 30 games.

Arizona had a solid run through a tough nonconference schedule and opened the Pac-12 by wrapping wins over rival Arizona State and Southern California around a loss to UCLA.

Oregon State picked up a win over Texas while going 10-2 in nonconference, but has struggled since the Pac-12 started, losing three of four. The latest was the toughest: 103-101 to Stanford in quadruple overtime Saturday in the longest game in school history.

The Beavers have at least been scoring, coming into the game tied for fourth in the nation with 84.4 points per game, sixth in assists at 18.1 and ninth at 49 percent shooting while tying the school record with three 100-point games this season.

The Wildcats have had a few high-scoring games of their own, too, so this had the potential to be a shootout.

Nope.

Missing tough shots against tight defense and easy ones with no defense, Oregon State and Arizona combined to miss 17 of their first 23 attempts.

It didn't get a whole lot better, either.

The Beavers missed their first seven 3-point attempts, including an air ball by Starks on an open shot from the top of the arc, finishing the half 2 for 10 while shooting 31 percent.

The Wildcats were a whole percentage point better, making 9 of 28 shots and just 3 of 8 free throws.

The result was an ugly halftime score: Oregon State 28, Arizona 26.

The second half was more like what everyone expected.

Oregon State had the jump early, hitting 6 of its first 10 shots, going up five after Cunningham hit a pair of 3-pointers.

Arizona was even better, hitting 8 of 12 to go up four with 7 minutes left. Lavender was the catalyst, hitting a pair of 3-pointers to help the Wildcats trim their deficit, then two more to put them up 58-54 with 7 minutes left.

Lavender hit his fifth 3 to put Arizona up five, but Starks answered quickly with a long one and tied the game at 67-all on a hard drive with 2 minutes left.

Starks and Fogg traded baskets in the closing seconds to send it to overtime, where Arizona pulled away for a hard-fought — nearly literally — win at home.
