EUGENE, Oregon (Ticker) -- Chris Hernandez and Matt Haryasz ignited a furious second-half rally that kept second-ranked Stanford unbeaten.
Hernandez scored all 22 points after halftime and Haryasz added 19 points and seven rebounds to lead the Cardinal to an 83-80 Pac-10 Conference victory over Oregon.
The Cardinal (18-0 overall, 9-0 Pac-10) trailed by as many as 19 points in the second half. Led by Hernandez, they stormed back to stun the sellout crowd at McArthur Court, where Oregon was unbeaten this season.
"Oregon is a great basketball team, but there is something about our guys," Stanford coach Mike Montgomery said. "They never give up and they rallied back for a great win."
Hernandez' three-point play with 4:32 remaining tied the game at 67-67, the first tie since the game's early moments. His two free throws put Stanford up for good, 77-75, with 1:21 to go.
After Hernandez made a pair at the line for the final margin, Oregon's James Davis threw up a desperation heave from at least 30 feet away that hit the back rim as time expired.
Haryasz was filling in for injured power forward Justin Davis, who was out with an injured knee. It was Haryasz' first career start.
"It was natural to be a little nervous and a little tentative in the first half," Haryasz said. "But in the second half, I just said 'forget it, I'm gonna play ball.'"
All-American candidate Luke Jackson led the Ducks (10-6, 5-4) with 25 points and Davis added 19. Oregon held a 45-26 cushion with 16:43 to play, before Stanford came alive.
"We broke down defensively in the second half," Oregon coach Ernie Kent said. "Hernandez did a great job of attacking the gaps. I am proud of the team. Hopefully we can learn from this."
The Cardinal shot a dismal 28 percent in the first half, but turned things around with a sizzling 64 percent (18-of-28) performance in the second.
Stanford is one of the most balanced teams in the country with all five starters averaging in double figures. On an afternoon when leading scorer Matt Lottich scored 15 points, other members of the team pitched in.
"Somebody can always step up for us," said forward Josh Childress, who scored 12 points. "Tonight, it was Chris and Matt. Next Thursday, it will be someone else. We don't have one guy that a team can key on."
Stanford becomes just the seventh team in Pac-10 history to hit the halfway point undefeated. The Cardinal have won 13 of the last 15 meetings with the Ducks.
Stanford and St. Joseph's are the lone unbeaten teams in Division I with matching 18-0 marks.
