LAS VEGAS — Azoulas Tubelis had 20 points and 11 rebounds, Justin Kier added 13 points and No. 2 Arizona pulled away late to beat Colorado 82-70 Friday night in the Pac-12 Tournament semifinals.
Arizona played without point guard Kerr Kriisa, who sprained his right ankle in the closing seconds of an 84-80 win over Stanford in the quarterfinals.
The top-seeded Wildcats (30-3) had a good offensive flow in the first half with Kier running the show, but weren't nearly as efficient through most of the second.
Arizona gradually stretched the in the closing minutes and used a 7-0 run to go up 78-65 with just over a minute left. The Wildcats will play the winner between No. 13 UCLA and No. 21 Southern California in the title game Saturday night.
No. 4 seed Colorado set a Pac-12 record with 16 3-pointers, but went 8 for 30 on 2-pointers to miss out on a chance to play in consecutive Pac-12 title games. The Buffaloes went on a 12-2 run to erase a nine-point halftime deficit, but went into an offensive funk as Arizona started to stretch the lead.
Jabari Walker led Colorado with 19 points, but had just two in the second half.
The Wildcats and Buffaloes split the regular-season series, each winning blowouts at home with dominating second halves.
The third meeting was also close at halftime — and an offensive Vegas show.
Colorado hit seven of its first nine shots to go up eight early, went through a brief funk and went 9 of 15 from 3 in the first half. Walker hit all five of his 3-pointers and had 17 points.
The Wildcats had no drop in efficiency with Kriisa in a walking boot, working its inside-out game to near perfection while hitting 17 of 28 shots.
Tubelis was their go-to player, scoring 18 points, mostly in the post and on short jumpers. He jumped a passing lane for a steal and finished off a three-point play with 3 seconds left to give Arizona a 47-38 halftime lead.
Colorado was the Pac-12's best 3-point shooting team during the regular season and upped its pace in the Pac-12 semifinals. The Buffaloes just weren't good enough inside the arc and now have to hope their resume is good enough to earn an NCAA Tournament bid.
Arizona had some offensive issues in the second half after lighting it up in the first, but locked down Colorado down the stretch to earn its first trip to the Pac-12 title game since 2018.
