Rosco Allen scored nine of his 17 points in the final 5:34, freshman Marcus Sheffield added a season-high 17 points and Stanford upset visiting No. 21 Utah, 70-68, in overtime of the Pac-12 men's basketball opener Friday in Maples Pavilion.
The Cardinal (1-0, 8-4), which hosts Colorado in a Pac-12 contest on Sunday at 7 p.m., has a three-game winning streak and has won six of seven overall.
Allen slammed home the tying basketball with just over 10 seconds left in regulation and Utah missed four foul shots in the final 19 seconds, moving the game into overtime.
"I knew I had to be clutch," Allen said. "We had to come down and execute."
Utah appeared to be in control of the game with a 42-30 edge less than five minutes into the second half. The Cardinal had other ideas.
"It's not always pretty but these guys somehow found a way to give us a chance to win," Stanford coach Johnny Dawkins said. "It's one thing to talk about beating a team that's ranked and it's another to beat a team that's ranked. It shows the possibilities."
Sheffield reached double figures in scoring for a second straight game and hit several key baskets during the second half that helped keep the Cardinal close.
Allen and Sheffield are a combined 23-of-42 (.548) from the field over the past two games for Stanford, which had another four players in double figures. Marcus Allen had 14 points and Michael Humphrey added 13 to go with a team-high eight rebounds.
"Growing up I always dreamed of something like this," Sheffield said. I'm getting more comfortable and playing with confidence when I'm on the court."
Rosco Allen saw this coming from Sheffield.
"He's a super smooth player," Allen said. "He has all the moves in the book. He can take a guy 1-on-1 and really finish."
Allen, one of the team captains, reached double figures in his seventh straight game.
" Our defense was more active in the second half," Allen said. "They played more of a match-up zone and that stumped us in the first half. We made some adjustments and did some things differently.""
The Cardinal rallied to tie the game at 45 when Humphrey, who scored eight points during the comeback, hit a pair of free throws with 9:30 remaining to play.
Sheffield hit a jumper to put the Cardinal in front, 47-46, with 8:16 left but the Utes regained the lead a minute and the game stayed close until Rosco Allen gave into a groove.
"He's been there for us," Dawkins said. "It's been special seeing him grow into role."
The game was tied at 10 when the Utes went on a 9-0 run while Stanford missed eight
straight shots and went scoreless over a seven-minute stretch.
Utah eventually took a 30-21 advantage into the intermission.
Three Stanford wrestlers reached the quarterfinals of the Defense Soap & Flips Wrestling Southern Scuffle in Chattanooga, Tenn., while six other Cardinal are still alive in the consolation brackets.
Fourth-ranked freshman Joey McKenna (141 pounds), redshirt freshman Paul Fox (149 pounds) and redshirt sophomore Nathan Butler (285 pounds) are the three Cardinal who have advanced to the quarterfinals.
