The Wildcats (28-6) boosted their case for a No. 2 seed in the NCAA tournament. UCLA (29-5) still hopes to land the No. 1 seed in the West and return to Las Vegas in two weeks for the regional.
It was the second year in a row Arizona beat UCLA in the Pac-12 title game.
Arizona second-year coach Tommy Lloyd can’t lose in Las Vegas. He is 9-0 in this city, 8-0 at T-Mobile Arena and 6-0 in the Pac-12 Tournament.
Ramey’s 3-pointer put the Wildcats ahead 60-58. The clutch shot came after teammate Azuolas Tubelis missed a 3 that was rebounded by Pelle Larsson. He tossed to Ramey, who shook a defender and connected from the top of the key.
UCLA guard Tyger Campbell was fouled with 6.8 seconds left, and he made the first free throw but missed the second. Tubelis hit one of two free throws with 5.8 seconds to go, and UCLA’s Dylan Andrews missed a 3 at the buzzer to ensure Arizona’s victory.
Tubelis had 19 points and 14 rebounds for second-seeded Arizona. Oumar Ballo scored 13 points and Larsson had 11.
Amari Bailey led top-seeded UCLA with 19 points. Campbell scored 16 and Jaime Jaquez Jr. totaled 13 points and 10 rebounds.
The Bruins knew coming in they wouldn’t have guard Jaylen Clark (lower leg) or Adem Bona (shoulder), and their problems only mounted when two of Bona’s replacements in the post got into foul trouble.
Mac Etienne and Kenneth Nwuba each had four fouls in the second half, forcing coach Mick Cronin to play at least one of them. Etienne fouled out with 9:35 left and Nwuba with 4:27 remaining, meaning the Bruins had to play with a smaller lineup the rest of the game.
Arizona wasn’t completely healthy, either. Point guard Kerr Kriisa has been playing with a balky shoulder this tournament.
