LAS VEGAS -- UCLA's Jordan Adams, who broke his right foot on the last play of the game, fueled a Bruins rally in the second half to spark a 66-64 victory over Arizona at MGM Grand Arena on Friday night.
The victory sends the Bruins into the Pac-12 Tournament championship game Saturday night.
Adams scored 18 of his game-high 24 points in the second half, including 14 consecutive at one point. UCLA coach Ben Howland did not immediately confirm that Adams' foot was broken and told reporters the freshman guard needed X-rays.
A UCLA spokesman later confirmed Adams suffered a broken fifth metatarsal in his right foot and is out for the remainder of the season.
The Bruins (25-8) advance to play the winner between Oregon and Utah on Friday night for the championship and automatic bid for the NCAA tournament.
"Jordan Adams really stepped up, and they made big plays," Arizona coach Sean Miller said. "That's what March is about, making big plays."
Adams' jumper with 3:53 remaining tied the game at 58-58 after the Bruins had trailed by as many as 11 points during the second half. Shabazz Muhammad's two free throws with 3:11 remaining gave UCLA a 60-58 lead, the Bruins' first advantage since 16:36 remained in the first half.
Grant Jerrett's 3-pointer for Arizona tied the game at 64-64 with 55 seconds remaining. UCLA answered with Kyle Anderson's put-back to give the Bruins the 66-64 advantage with 23 seconds left.
Arizona's Solomon Hill missed a jump shot with five seconds remaining, with ball rattling in and out. The Wildcats could not get off another shot.
"We played well enough to win, but we just at the very end, didn't have enough plays," said Miller, whose technical foul with 4:37 remaining helped UCLA's surge.
Adams' two free throws -- which were the 12th points of his 14-point personal run -- after Miller's technical tied the game at 56-56. Miller was assessed the technical by official Michael Irving for arguing an out-of-bounds possession change, giving UCLA the ball.
"I didn't cuss," Miller said. "I didn't challenge (Irving). By the way, it's my first technical foul of the year."
UCLA's cold perimeter shooting and subpar play from Muhammad, its leading scorer, and playmaker Larry Drew II spelled doom for the Bruins for most of the game until Adams' scoring outburst.
Muhammad, who averages 18.3 points, was limited to only six points and Drew produced only two assists with 9:39 remaining in the game and the Wildcats ahead 49-42.The Bruins were also 0 for 9 from 3-point range at that juncture.
"I tell you what? Everybody's dialed in on Shabazz," Howland said about the defense Hill, a senior, played on his freshman star. "God bless him. He's seeing the best team's defender night in and night out, and they're really coming after him. And I love Hill.
"When I did my all league voting, I voted Cal's (Allen) Crabbe, because I can't vote for my own players, number one, and then I voted Hill number two in the conference."
Muhammad came to life, scoring five consecutive points for UCLA to cut the Arizona lead to 49-45 with 9:10 remaining. Adams added to UCLA's 9-0 run, making a baseline jumper with 8:14 left to cut the lead to 49-47.
Adams' consecutive baskets trimmed Arizona lead to two again, 53-51 with 5:24 remaining. He made UCLA's first 3-pointer with 4:44 left in the game to cut the lead to 56-54 before Miller was charged with his technical.
"It happens all the time," Howland said of Adams' scoring spurt. "I mean, he really had it going. He leads the conference in steals in conference games. He's eighth in the league in scoring. He is a really good player."
Adams finished 6 of 13 from the field and 11 of 13 from the free-throw line. He attempted more free throws than Arizona did as a team. The Wildcats made 7 of 9 attempts.
Muhammad was limited to 11 points on 4-of-11 shooting from the field and Drew finished with four assists but he was steady with two turnovers in 37 minutes.
UCLA had only five turnovers compared to Arizona's 13.
"I think we did a good job of keeping our composure," UCLA freshman guard Kyle Anderson said. "The leaders on our team stressed to the five guys that are out there that we have to stay calm, being down 11 or 9 or whatever it was.
"I think that's what we did a really good job of and we were able to fight back for a second time and end up with the win.
NOTES: UCLA is now 3-0 against Arizona after sweeping the regular-season series. It is the second time UCLA is 3-0 against Arizona. The Bruins also achieved that in 2006. Arizona has tried to beat UCLA three times on two occasions in 2003 and 2010 but lost both times. ... The Bruins' three freshmen starters -- Adams, Anderson and Muhammad -- have accounted for 55.4 percent of UCLA's total points, 47.3 percent off the total rebounds and 43.1 percent of total minutes. They accounted for 45 of UCLA's 66 points against Arizona on Friday night.
