EUGENE — Johnathan Loyd's performance in a loss to California on Thursday was so dismal it spurred a late-night call of concern from his coach.
"I was worried about him," Oregon coach Dana Altman. "But he bounced back tough."
He certainly did.
Loyd had his best game of the season with 15 points and nine assists to lead No. 23 Oregon past Stanford 77-66 on Saturday, keeping the Ducks (22-6, 11-4 Pac-12) tied with No. 12 Arizona atop the league standings.
Carlos Emory led the Ducks with 19 points and Arsalan Kazemi had 15 as Altman got his 600th career win.
E.J. Singler added 12 points and Tony Woods had nine points and nine rebounds for Oregon.
"Lots of guys played well but Johnny was the guy who stirred the drink," Altman said.
Loyd, making his ninth start in place of injured point guard Dominic Artis, was 6 of 8 from the field for a season high in points and a career high in assists.
It was a much different performance than his 0-for-6, no-point effort in a 48-46 buzzer-beating loss to the Golden Bears.
"It felt great tonight," Loyd said. "I needed it. My teammates had faith in me. They kept telling me they believed in me so I just stepped up."
Dwight Powell led the Cardinal (16-12, 7-8) with 16 points and Josh Huestis had 12 points and 13 rebounds.
Oregon led 30-26 at halftime but outscored the Cardinal 11-4 early in the second half to go up 46-34 with 13:50 to play and Stanford never got closer than 10 points the rest of the way.
The Ducks shot a season-worst 27.6 percent against California on Thursday and it looked like things were on the same track when Damyean Dotson and Singler air-balled shot attempts in the opening minutes against the Cardinal.
But after falling behind 14-7, Oregon heated up.
The Ducks scored eight straight points, two on a short jumper from Loyd that put them up 15-14 with 11:01 to play in the half.
Stanford regained its lead 3:09 before halftime when Huestis capped a 6-0 run with a rebound dunk to make it 24-23.
Loyd followed with a 3-pointer, then dished to Kazemi for a dunk and made two free throws to help Oregon take a 30-26 halftime lead.
California 60, Oregon State 59
At Corvallis, Justin Cobbs had 18 points and surging California won its fifth straight game by holding off a late Oregon State rally.
California (18-9, 10-5 Pac-12) has won seven of its last eight games, including victories over then-No. 7 Arizona and No. 23 Oregon.
The Golden Bears led by as many as 14 points but Oregon State cut it to 45-42 on Joe Burton's layup with 8:32 left in the game. The Beavers (13-15, 3-12) stayed within reach and Devon Collier's layup cut Cal's lead to 58-55 with 1:47 left.
Justin Cobbs hit a jumper from atop the key for California before Collier made four straight free throws to come within 60-59 with 43 seconds left.
With 10 seconds left, Cobbs missed a jumper out front. But Ahmad Starks' 3-point attempt missed with a second left on the clock to end it.
Burton, a senior playing his last game at Gill Coliseum, had 15 points, nine rebounds and seven assists.
No. 12 Arizona 73,Washington State 56
At Tucson, Ariz., Kevin Parrom matched his career best with five 3 pointers — in six tries — scoring a season-high 19 points and leading No. 12 Arizona past Washington State 73-56 on Saturday.
Parrom opened the game with two 3s and the Wildcats (23-4, 11-4 Pac-12) led all the way. Arizona was up by as many as 21 points early in the second half before the Cougars cut it to 11 late.
Mark Lyons added 14 points and freshman Kaleb Tarczewski had a career-best 12 for the Wildcats, who began the day tied with Oregon atop the Pac-12. Brock Motum scored 20 points but missed six free throws for the last-place Cougars (11-17, 2-13), who lost their eighth straight. DaVonte Lacy added 10 points, eight in the second half.
Washington 68, Arizona St. 59
At Tempe, Ariz., Scott Suggs scored 16 points and hit a 3-pointer with 34 seconds left, helping Washington hold off Arizona State.
Washington (15-13, 7-8 Pac-12) led by 12 midway through the second half and nearly blew it all, allowing the Sun Devils to pull within one. Abdul Gaddy, who had 13 points, hit a big jumper and Suggs followed with his 3-pointer to keep Arizona State from completing the comeback in its seniors' final home game.
Washington dominated the Sun Devils inside in the teams' previous meeting and again gave them trouble, grabbing 13 more rebounds and scoring 14 points off 14 offensive boards. Arizona State (20-8, 9-6) came up short against Washington for the second time this season and in its bid to match the school record for home wins with 16. Ruslan Pateev, Jahii Carson and Evan Gordon had 10 points each for the Sun Devils.
