EUGENE, Ore. (AP) - E.J. Singler scored 14 points and Oregon overcame a slow start to beat No. 4 Arizona 70-66 on Thursday night, handing the Wildcats their first loss of the season.
Dominic Artis, Carlos Emory and Tony Woods had 10 points apiece for the Ducks (13-2, 2-0 Pac-12), who have won 17 straight home games, including all 11 this season.
Mark Lyons scored 21 and Solomon Hill added 16 points to lead the Wildcats (14-1, 2-1), who entered as one of three undefeated teams in the country.
It appeared they were going to stay that way when the Wildcats jumped out to an 11-0 lead. But it was all Oregon from there, as the Ducks outscored Arizona 41-19 the rest of the first half to lead 41-30 at the break.
Arizona trimmed its deficit to 48-42 early in the second half but got no closer until Lyons hit a 3-pointer with 1:18 to play that made it 67-63.
A 3-pointer by Arizona's Nick Johnson with 50 seconds remaining made it 69-66, but Johnathan Loyd hit a free throw with 9.2 seconds left to seal the Ducks' second win against a ranked team this season. They beat No. 24 UNLV in November.
No. 9 GONZAGA 83, SAINT MARY'S 78
SPOKANE, Wash. (AP) - Kelly Olynyk scored 31 points and Gonzaga held off Saint Mary's in the latest installment of one of the best rivalries on the West Coast.
Kevin Pangos added 22 points for Gonzaga (16-1, 3-0 West Coast Conference), which has won seven straight since losing at home to Illinois. It was Olynyk's second consecutive 30-point game.
Stephen Holt led Saint Mary's (12-4, 1-1) with 23 points.
Gonzaga led by 20 early in the second half but had to stave off a furious rally by the Gaels.
Matthew Dellavedova hit a 3-pointer and then two free throws to cut Gonzaga's lead to 79-78 with 15 seconds left. Olynyk sank a pair of free throws before Dellavedova missed a long 3-point attempt with 6.9 seconds to go. The Gaels were forced to foul, and Pangos hit two free throws to seal it.
No. 22 MICHIGAN STATE 62, IOWA 59
IOWA CITY, Iowa (AP) - Branden Dawson scored a career-high 17 points, including a late steal and tiebreaking dunk that helped Michigan State beat Iowa.
Gary Harris had 14 points for the Spartans (13-3, 2-1 Big Ten), who hung on late for their eighth win in nine games.
Dawson ripped the ball away from Iowa freshman Mike Gesell and gave Michigan State a 58-56 lead with 49 seconds left.
Anthony Clemmons missed a free throw that would have tied it with 12 seconds to go and airballed a 3-pointer at the buzzer as Iowa (11-5, 0-3) lost its third straight.
The Hawkeyes played without leading scorer Devyn Marble, who sprained his ankle in practice this week.
Zach McCabe led Iowa with 15 points and fellow reserve Melsahn Basabe added 14.
