LAS VEGAS Utah has taken down two higher seeds in the Pacific-12 Conference tournament.
Two more, and the Utes' postseason will continue.
Jarred DuBois scored 21 points and hit a tying three-pointer in the closing seconds of regulation, Jordan Loveridge scored eight of his 20 points in overtime, and Utah upset second-seeded Cal 79-69 in the quarterfinals Friday night.
"If you watch basketball at all levels, the team that plays the hardest usually wins," Utah coach Larry Krystkowiak said. "So I think that's what we're doing right now. We're playing with some confidence. We've got some guys that are stepping up."
Utah (15-17) knocked off seventh-seeded USC in its opener and took down No. 2 by hitting some big shots down the stretch.
The 10th-seeded Utes trailed 59-56 in regulation after Allen Crabbe hit two free throws. But Utah worked the ball around to DuBois, who hit a contested three-pointer with four seconds left to tie the score. Utah dominated overtime and will move on to face Oregon in tonight's semifinals.
Cal (20-11) needed to play well in the Pac-12 tournament to ensure an NCAA invitation but now must wait three anxious days to find out if it will get an at-large bid.
Justin Cobbs had 26 points and Crabbe 21 for the Bears.
"We had our chances. We were there," Cal coach Mike Montgomery said. "We knew it was going to be a tough game. We knew this conference is tough, top to bottom. Had our chances to finish it off and just didn't do our job."
No. 21 UCLA 80, Arizona State 75 in Las Vegas Shabazz Muhammad scored 12 of his 16 points in the second half, Travis Wear hit a jumper with 11 seconds left, and the top-seeded Bruins (24-8) rallied from a 15-point deficit to beat the ninth-seeded Sun Devils (21-12).
Wearing new uniforms with sleeves and camouflage-patterned shorts that looked like pajamas, UCLA played as if barely awake well into the second half.
UCLA rallied behind Muhammad, who scored 10 points during a 17-4 second-half run.
Wear hit a long jumper to put the Bruins up 78-75, and Arizona State's Jonathan Gilling missed a three-point attempt in the corner to help UCLA avoid becoming the second straight No. 1 seed to lose its opener.
Larry Drew II had 20 points and Wear 15 to send the Bruins into tonight's semifinals against No. 18 Arizona.
Jahii Carson had 21 points, seven assists and six rebounds to lead Arizona State. Jordan Bachynski had 22 points and Gilling 17 for the Sun Devils, who must wait until Sunday to see if they'll receive an at-large bid to the NCAA Tournament.
No. 18 Arizona 79, Colorado 69 in Las Vegas Nick Johnson scored 18 points and hit a contested shot with 34 seconds left, helping the fourth-seeded Wildcats (25-6) beat the fifth-seeded Buffaloes (21-11).
Arizona led by 14 in the second half but had trouble shaking desperate Colorado.
Johnson hit his shot between three defenders to put the Wildcats up by four and followed teammate Mark Lyons' two free throws by swatting Askia Booker's three-point attempt into Colorado's bench.
Lyons had 14 points and Solomon Hill 13 for Arizona.
Colorado won last year's conference tournament with four wins in four days and opened this year's tournament with a six-point victory over Oregon State. Now the Buffaloes must hope for an at-large berth in the NCAA Tournament.
Oregon 80, Washington 77 (OT) in Las Vegas Tony Woods had 19 points, Arsalan Kazemi scored 11 of his 14 in overtime, and Oregon outlasted Washington in the quarterfinals.
The tournament's third seed, Oregon (24-8) found itself in a fight from the start against the sixth-seeded Huskies. The Ducks stopped Washington from getting off a shot in the closing seconds of regulation and held on in overtime.
A year ago, Washington (18-15) became the first team from a power conference to miss the NCAA Tournament after winning the regular-season title, thanks to an opening loss to Oregon State in the Pac-12 tournament.
The Huskies could be out of the bracket after coming up short again in this year's tourney.
