Alex Barlow enrolled at Butler because he wanted to learn how to coach from Brad Stevens.

Saturday, the 5-foot-11 walk-on hit the biggest shot of the game as the Bulldogs upended No. 1 Indiana 88-86 in overtime in Indianapolis.

When Indiana's defenders failed to converge on Barlow, he kept right on going through the lane, drove to the basket and hit a spinning 6-foot jumper for the winning basket with 2.4 seconds left.

"Not in my wildest dreams did I really think that would be reality," Barlow said after his floater touched every part of the rim and fell through.

Barlow, who spurned college scholarship offers to play his best sport, baseball, and to learn from Stevens, found himself in the spotlight after three Butler players fouled out.

The sophomore who had scored only 12 points in nine games this season and 18 in his college career finished with a career-high six points. He came up with a steal that led to a go-ahead 3-pointer late in overtime and finally won it with a shot that bounced off the back of the rim, straight into the air and finally through the net.

"I just figured I would throw it up to the rim," Barlow said. "If I missed it, I knew they wouldn't get a shot off."

Rotnei Clarke scored 19 points for Butler (8-2), which beat a No. 1 team for the first time in five tries. Roosevelt Jones had 16 points before fouling out in regulation, and Andrew Smith finished with 12 points and held national player of the year candidate Cody Zeller in check until fouling out.

Zeller had 18 points, including a layup to tie the score at 86 with 19.3 seconds left in overtime, for Indiana (9-1).

Stanford 75, UC Davis 52: Dwight Powell sat on the bench for all but two minutes of the first half because of foul trouble. He made up for it in the second half.

Powell scored all 20 of his points after intermission in leading the Cardinal (7-3) past the Aggies (1-6) at Maples Pavilion.

"Coach (Johnny Dawkins) told me to stay ready and keep my head in the game," Powell said. "I stayed engaged as much as possible."

Josh Huestis added 14 points and nine rebounds for Stanford. Chasson Randle scored 12 points.

J.T. Adenrele scored 23 points for UC Davis.

Powell made his first eight shots of the second half

"He showed maturity to come back with 20 points," Dawkins said. "I'm proud of him. In earlier years, I don't know that he comes back to that level."

Santa Clara 75, Pacific 71: Evan Roquemore scored his 1,000th point as a Bronco on two free throws to ice the victory with 2.7 seconds left as Santa Clara (8-2) held off the host Tigers (5-5).

Kevin Foster led SCU with a season-high 31 points. Foster was 1 for 10 on 3-point shots until the final minutes, when he hit three in a row. Roquemore finished with 21 points and eight assists, and Marc Trasolini contributed 13 points and 12 rebounds.

Nevada 59, USF 51: Deonte Burton scored 14 points, and the host Wolf Pack (7-4) held off the Dons (5-3).

Cole Dickerson had 11 points and nine rebounds for USF, which pulled to within 51-49 with 2:41 to play.

Arizona 65, Florida 64: Mark Lyons hit a contested layup with 7 seconds left, and the No. 8 Wildcats (8-0) rallied from a six-point deficit in the final minute to defeat the No. 5 Gators (7-1) in Tucson.

Lyons, who scored 14 points, got the winning basket after Florida's Kenny Boynton missed the front end of a 1-and-1.

Solomon Hill had 18 and Nick Johnson 15 for Arizona, which is off to its best start since 1998-99.

Louisville 87, Memphis 78: Chane Behanan scored 22 points, and the No. 6 Cardinals (9-1) rallied from 16 points down in the first half to beat the host Tigers (6-3).

Louisville was 38 of 46 from the free-throw line as five Memphis players fouled out. The Tigers, led by Joe Jackson's 23 points, were 14 of 20 at the line.

Gonzaga 68, Kansas State 52: Kelly Olynyk scored 20 points to help the No. 14 Bulldogs (10-1) beat the Wildcats (7-2) in Seattle.

Big East breakup: The seven Big East schools that don't play major college football are separating from the conference many of them founded so they can build a league focused on basketball.

The presidents of the seven schools made the announcement Saturday, two days after their intentions were first reported.

The seven schools venturing out on their own are: Georgetown, St. John's, Villanova, DePaul, Marquette, Seton Hall and Providence.

Stanford 78, Pacific 43: Chiney Ogwumike scored a career-high 31 points to go with 13 rebounds, and the No. 1 Cardinal (9-0) routed the visiting Tigers (7-2).

Junior Mikaela Ruef added career bests of 13 rebounds and five assists for Stanford, which won its 82nd consecutive home game -- the longest active streak in the nation. Joslyn Tinkle had 10 points.

Pacific had no answer for Ogwumike, who was 14 of 18 from the floor. She pulled down seven offensive rebounds, which led to many easy baskets and allowed Stanford to outscore Pacific 21-2 in second-chance points.

USF 92, San Jose State 64: Mel Khlok scored 29 points to lead the host Dons (6-4) past the Spartans (3-7).
