Kyle Fogg had 23 points to lead the Arizona Wildcats to an emotional 81-73 overtime win over Oregon State in a game that was marred by a late shoving match.

The skirmish, which resulted in ejections to UA's Kyryl Natyazhko and OSU's Joe Burton and two other technical fouls, obscured a wild game that was shot poorly by both teams in the first half and featured a shootout by UA's

Brendon Lavender and OSU's Ahmad Starks in the second half.

Lavender tied his career high with 18 points, hitting 5 of 6 threes, while Starks scored 10 points in the final three minutes of regulation.

The win moved Arizona to 12-5 overall and 3-1 in the Pac-12. OSU dropped to 11-6 and 1-4.

The two teams will not meet in Corvallis this season because of the Pac-12's unbalanced schedule.

The Wildcats went on a 7-0 run in overtime to take a 79-72 lead but the last score set off the fireworks between the teams.

After Fogg made a layup to give UA the seven-point lead and picked up a foul, he bumped OSU's Jared Cunningham and appeared to talk to him, prompting Cunningham to push back. Then UA forward Solomon Hill approached Cunningham and, according to replays, appeared to be winding up to throw a punch.

Toward the end of the skirmish, UA coach Sean Miller found himself pushing both Hill and Kyryl Natyazhko back to the bench, giving Natyazhko a hard shove to the shoulder.

Both Burton and Natyazhko were thrown out on the play, because they both left their benches to join the skirmish, and rules dictate players doing so must be ejected.

Meanwhile, Fogg and Cunningham were given technical fouls. Cunningham and Fogg fouled out, with Cunningham also having picked up a personal foul on Fogg's layup. Jesse Perry took the ensuing free throw for Fogg, but missed.

UA still went on to coast in the final minute.

Lavender and Starks held a furious shootout at the end of regulation, with Lavender hitting five three pointers over the half and Starks catching fire in the final minutes.

Starks put OSU ahead 72-70 with a 14-foot jumper but Arizona's Kyle Fogg scored inside to tie it at 72 with 14 seconds left and Starks missed a final jump shot just before the buzzer to send the game into overtime.

Starks had earlier given the Beavers a 70-69 lead when he hit a three-pointer from the top of the key over Arizona's Jordin Mayes, giving him eight points over a two-minute span as OSU tried to overcome Lavender's heroics.

Lavender tied his career high of 18 points with a fifth three-pointer, with 3:32 left, that gave Arizona a 67-62 lead. However, Starks answered back with a quick, unguarded three-pointer from the top of the key that cut it to 67-65 with 3:16 left.

Lavender hit two more three-pointers on back-to-back UA possessions, giving the Wildcats a 58-54 lead with 7:27 left.

Lavender hit 4 of 5 threes through the first 13 minutes of the second half after not hitting any in the first half.

Arizona tied the game at 44 with 12:16 left when Jordin Mayes made a pair of free throws, and Lavender hit his second three-pointer within two minutes shortly afterward to give UA a 47-44 lead.

Cunningham hit his third and fourth three pointers of the game over a 49-second span early in the second half. More known for his explosiveness and dunking, Cunningham had not made more than two three-pointers in a game during his career.

Cunningham's fourth three gave OSU a 38-34 lead with 17:01 left.

In the first half, Cunningham scored 10 points to lead Oregon State to a 28-26 halftime lead over Arizona in a poorly shot first half by both teams at McKale Center tonight.

The Wildcats made just 32 percent of their field goals, and OSU hit just 31 percent. But the Beavers outrebounded UA 26-18 and had two late three-pointers from Cunningham toward the end of the half.

Arizona was led by Kyle Fogg, who had eight points, while Nick Johnson had six points on a pair of three-pointers.

The Beavers were coming off a four-overtime loss to Stanford and looked shaky in the early minutes. OSU made just 2 of its first 13 field goals, while Arizona took an early 14-7 lead, getting two early threes from Kyle Fogg plus others from Nick Johnson and Josiah Turner.

Arizona had a 14-9 lead at the second media timeout, with 11:42 left. The Wildcats were shooting just 4 of 11 from the field at that point.

The Wildcats' lead shrunk to 16-13 with 7:56 to go despite the fact that OSU had made just 5 of 21 field goals, missing all five threes it had taken to that point.

Then, with 2:36 left, OSU's Joe Burton tied the game at 21 when he hit one of two free throws, and a three-pointer from Cunningham gave OSU a 26-23 lead.

Cunningham, who entered the game hitting just 27 percent from three-point range, had also hit a three-pointer to pull the Beavers to within 21-20 with just over four minutes to go in the first half.
