Valparaiso proved it was more than just a one-shot wonder from a small Hoosier town in a basketball-crazy state.

The Crusaders, champions of the unheralded Mid-Continent Conference, beat Florida State 83-77 in overtime Sunday to continue their surprising run through the NCAA tournament."We're a school of 3,500 and they (the Seminoles) are a school of 30,000," said Valparaiso coach Homer Drew. "Only in America and only in the NCAA tournament can you have the opportunity to go against the best athletes and best programs in America. We beat two schools from the best conferences in America.

"Now, you can meet me in St. Louie."

The smallest school in the tournament made it to the round of 16 when Bob Jenkins and Antanas Vilcinskas made follow shots in the final two minutes of overtime.

The Crusaders (23-9) will play the winner of Sunday's Kansas-Rhode Island game in St. Louis next Friday.

Bryce Drew, the coach's son whose buzzer-beating 3-pointer knocked out No. 4 seed Mississippi 70-69 in the first round, scored 22 points and made two free throws to ice it with 8.3 seconds left.

But it was the follow shots by Jenkins with 1:31 left, and another by Vilcinskas with 25.3 seconds remaining, knocked out the Seminoles, a No. 12 seed and the final at-large team selected for the tournament.

"This is everything our five seniors worked for," Bryce said.

"My job is to get rebounds and that's what I did," Jenkins said.

Valparaiso's appearance in the final 16 will be only the second time in history of the tournament that a No. 13 seed has made it that far. Richmond did it in 1988.

The Crusaders' Bill Jenkins made one of two free throws with 30.5 seconds left to tie it 75-all after Ronald Thompson had missed a free throw for Florida State.

"This was truly amazing," Bill Jenkins said. "I'm going back to the hotel and watch the highlights all night."

RHODE ISLAND 80, KANSAS 75: At Oklahoma City, Rhode Island's quickness gave No. 2 Kansas its quickest NCAA tournament exit in six years.

The Rams, behind the play of guards Cuttino Mobley and Tyson Wheeler, beat the top-seeded Jayhawks to stop Kansas' string of five straight trips to the regional semifinals.

Mobley had 27 points on 10-of-19 shooting, while Wheeler scored 20 and had eight assists to cap a weekend of upsets in this subregional. The Rams (24-8) will play 13th-seeded Valparaiso in the next round. Valparaiso beat Florida State, 83-77.

Kansas (35-4) got great games from its All-Americans, Raef LaFrentz and Paul Pierce, but they didn't get enough help. Billy Thomas was 2-of-15, including 2-of-13 from 3-point range, and the Jayhawks shot just 43 percent.

LaFrentz had 22 points and 14 rebounds, and Pierce scored 23.

Thomas had returned to the lineup and played well in a first-round blowout of Prairie View A&M. But he missed his first eight shots before making a 3-pointer that gave Kansas a 39-32 lead with 17 minutes left in the game.

Rhode Island came right back and the left-handed Wheeler tied the score at 45 with a 3-pointer. Mobley hit from long range on the next trip, then Antonio Reynolds-Dean converted a three-point play to give the Rams a 51-45 lead with 12:29 to play.

Two more baskets by Mobley and consecutive 3-pointers by Wheeler helped give the Rams their biggest lead, 65-55, with 8:24 remaining.

Pierce scored three points and assisted on a basket in a 7-0 run that brought the Jayhawks within 65-62 before Mobley gave Rhode Island some breathing room with a 3-pointer from the top of the key with 5:11 to play.

Kansas twice got within four after that, but no closer.

STANFORD 83, W. MICHIGAN 65: At Chicago, Stanford, a school known for its brains, used its muscle to win a trip back to the NCAA tournament's round of 16.

With Arthur Lee scoring from the outside and Tim Young and Mark Madsen using their size and strength to control the inside, the Cardinal overcame Western Michigan's quickness and beat the Broncos 83-65 in the Midwest Regional on Sunday.

"Our inside players clearly established and allowed us to have a place to go where Western Michigan simply couldn't handle us," Stanford coach Mike Mongtomery said. "It was a blend of inside-outside, big and little."

Western Michigan, the No. 11 seed in the Midwest, saw its chances of pulling off a second straight upset ended with 12:03 left when Rashod Johnson fouled out after he was assessed a technical foul, minutes after picking up his third and fourth personals.

Stanford (28-4) scored seven straight points in the sequence to take a 14-point lead.

PURDUE 80, DETROIT 65: At Chicago, opening tip. Game over. Once again, it was Purdue early - and decisively.

For the second consecutive game, Purdue took a large lead and was never caught. The Boilermakers, the second seed in the Midwest, defeated Detroit 80-65 Sunday and advanced past the second round of the NCAA tournament for only the third time in coach Gene Keady's 18 seasons.

Chad Austin scored 20 points and Brad Miller 18 for Purdue (28-7), which will meet third-seeded Stanford (28-4) in Friday's regional semifinals at St. Louis. The Cardinal beat Western Michigan 83-65 on Sunday.

The Boilermakers, who scored the first 18 points and defeated Delaware 95-56 in the first round, took a 24-8 lead in the opening 13 minutes against Detroit as the 10th-seeded Titans made only three of their first 21 shots.

Detroit (25-6) closed to 33-22 by halftime but Purdue began the second half with an 11-3 run and was never seriously threatened.
