SEATTLE (Ticker) -- After getting an unexpected test, Stanford finally got serious.
Josh Childress scored 10 of his 26 points in a late burst as the top-seeded Cardinal pulled away for a 71-45 victory over 16th-seeded Texas-San Antonio in the first round of the Phoenix Region.
"My performance could have been a lot better," said Childress, the Pac-10 Conference Player of the Year who was 9-of-15 from the floor. "There were a lot of times when I played without energy and I wasn't aggressive and that allowed them to back off."
Stanford (30-1) won its 10th straight first-round game and reached 30 wins for only the third time in school history, but not before the Roadrunners put a scare into the Cardinal.
In the city where it suffered its only loss of the season to Washington, Stanford found itself in a tight game after John Millsap's follow shot pulled the Roadrunners within 44-38 with 12:14 remaining, prompting coach Mike Montgomery to call a timeout.
"We got rattled a little bit," said Stanford forward Matt Haryasz, who chipped in with 10 points off the bench. "But as soon as that timeout came, the guys did a good job keeping their heads and we came out and played defense."
With the majority of the crowd rooting for Texas-San Antonio, the Cardinal seemed to flip a switch, scoring the next 14 points as part of a 23-2 surge. Rob Little's dunk started the run before back-to-back 3-pointers by Childress made it 52-38.
"I felt like we were on an away court," Little said. "I don't think we had a single fan here. You wouldn't expect that from a Pac-10 crowd. I guess all the Washington fans were here rooting against us."
LeRoy Hurd scored 18 points for the Roadrunners (19-14), who went more than 10 minutes without a basket. Childress went to the bench with 4:36 remaining with the Cardinal holding a 63-39 advantage.
"We got it to six and the place was going nuts, and then the timeout was made," Roadrunners coach Tim Carter said. "We just couldn't hit shots after that point."
While it made a run in the second half, Texas-San Antonio never figured out Stanford's defense, shooting under 24 percent (15-of-63). The Roadrunners also turned the ball over 20 times.
"When you're going to the basket, it's like you have three trees running at you when you're trying to put the ball up," Hurd said. "We were expecting them to be big, but it seemed like everybody out there was 6-7 and taller."
Stanford, which also was sloppy with 19 turnovers, opened a 37-23 halftime lead before allowing the Roadrunners to climb back into the game early in the second half.
"I thought San Antonio did a real nice job," Montgomery said. "They certainly were not intimidated. Our inability to rebound the ball hurt us, which is unusual. We were dead in the water there for a while."
The Cardinal will face Alabama in the second round Saturday.
