WEST LAFAYETTE, Ind. (AP) -- Sharon Versyp's old-school defensive philosophy still works.
Even against one of those trendy up-tempo offenses.
Whitney Bays had 20 points and 13 rebounds Saturday, Courtney Moses tied the school's career record for 3-pointers and the fourth-seeded Boilermakers rolled into the second round of the NCAA women's tournament with an emphatic 84-55 rout over usually high-scoring Akron.
"We always give our kids a challenge," Versyp said. "They are the ninth-best scoring team in the country, and we wanted to keep them under 60 today and we did that."
For the Boilermakers (22-8), it was a monumental day.
Versyp collected her 300th career win but refused to celebrate.
Moses tied Katie Gearlds' career mark by making her first two 3-pointers of the game, then missed her last five. The senior guard now has 238 and will get another chance to break the record in front of her home fans Monday night.
The victory margin was Purdue's fifth-most lopsided win in NCAA tourney history and their 50 rebounds were the second-most in tourney play.
Purdue is now 20-1 in first-round games, 20-7 in NCAA play on their home court and head into Monday night's showdown with fifth-seeded Oklahoma State with 11 wins in 14 games. The Cowgirls advanced by holding on for a 61-60 victory over Atlantic Sun champion Florida Gulf Coast, the No. 12 seed in the Notre Dame Regional.
And the Boilermakers won this one going away -- contrary to conventional wisdom and President Obama's upset pick.
Instead, Purdue's defense made all those doubters look foolish. The key was simple.
"I think we communicated really well," Moses said. "On screens, we were talking and switching and we really had each other's back."
Akron (23-10), the Mid-American Conference champion, was led by Rachel Tecca with 18 points and Hanna Luburgh with nine in its first ever NCAA appearance.
It wasn't nearly enough.
The Zips, who had won 16 of their last 17 dating to Jan. 15, shot 31.3 percent from the field, nearly matching a season low, and finished with a season worst point total. They were outrebounded 50-28 and Luburgh, the MAC scoring champion at 22.7 points, was a dismal 3 of 19 from the field.
Akron never had an answer for Versyp's tough, in-your-face defense.
"They are really long and lengthy and they put their biggest girl in front of Hanna," point guard Kacie Cassell said. "They knew our offense. They stopped it and we just couldn't get rebounds and couldn't get second-chance opportunities."
Whether it was frayed nerves or Purdue's defensive focus, nothing went right for the Zips.
The shooters never really got in sync and the Boilermakers made them pay a hefty price.
Moses knocked down both of her 3-pointers in the opening flurry and Dee Dee Williams closed the run with another 3 to make it 20-2 just 4:31 into the game.
That's when the Zips finally got started, but it was already too late. They went on a 13-6 run to close to 30-20, and rallied again after the Boilermakers extended the lead to 39-24. That 10-5 spurt got Akron back within 44-34 in the final minute of the first half but the Zips never got any closer.
DEPAUL 104, OKLAHOMA 100
DURHAM, N.C. -- Megan Rogowski scored 24 points and hit the go-ahead 3-pointer with 40.5 seconds left to help DePaul beat Oklahoma 104-100 in the first round of the NCAA tournament in the Lincoln Regional.
Chanise Jenkins added 21 points and Brittany Hrynko had 19 for the seventh-seeded Blue Demons (28-6). They blew a 19-point lead with under 16 minutes left, then rallied for a wild win.
They will play second-seeded Duke (28-6) on Monday night in the second round of the Lincoln Regional.
Aaryn Ellenberg had 36 points and seven 3s for the 10th-seeded Sooners (18-15), who set a tournament record for most points by a losing team in a regulation game. The 204 combined points also made it the highest scoring regulation game in the history of the NCAA women's tournament.
Oklahoma's Portia Durrett tied it at 97 with a layup with 48.2 seconds left.
Hrynko drove into the lane and found Rogowski in the left corner for an open 3 that put DePaul ahead for good.
DUKE 87, WINTHROP 45
DURHAM, N.C. -- Tricia Liston scored 20 points and Duke routed Winthrop.
Freshman Oderah Chidom added 17 points for the second-seeded Blue Devils (28-6).
They didn't miss a beat in their first game in nearly two weeks: They never trailed, shot 54 percent and led by double figures for the final 33 1/2 minutes in winning their 21st straight NCAA tournament opener.
In giving the 15th-seeded Eagles (24-9) their worst loss of the season by far, Duke built a 49-23 rebounding advantage and held them to 27 percent shooting -- 21 percent in the decisive first half -- to advance in the Lincoln Regional bracket.
Big South player of the year Dequesha McClanahan had 22 points to lead Winthrop in its brief first NCAA tournament appearance.
NEBRASKA 74, FRESNO ST. 55
LOS ANGELES -- Jordan Hooper had 23 points and 11 rebounds, and fourth-seeded Nebraska defeated Fresno State, 74-55.
Emily Cady added 15 points and 11 rebounds for the Cornhuskers (26-6), the Big Ten tournament champions who have won 13 of 14 games.
Taylor Thompson was the only player in double figures with 14 points for the 13th-seeded Bulldogs (22-11). They closed within four points early in the second half, but never got any closer in falling to 0-7 in the NCAA tourney. The Mountain West tourney champions had their eight-game winning streak snapped.
The Huskers advanced to play either No. 5 seed North Carolina State or 12th-seeded BYU in Monday's second round at Pauley Pavilion on the UCLA campus.
Tear'a Laudermill added 13 points, and Rachel Theriot had 10 points and 12 assists for the Huskers, who controlled the boards, 46-35.
The Bulldogs opened the second half on a 15-9 run to close to 38-34, getting four points each from three different players. Their bench outscored Nebraska's reserves, 20-7.
The Huskers answered by outscoring Fresno State 14-7, including two 3-pointers each from Hooper and Laundermill, to go up 52-41. From there, the Huskers cruised to the finish.
Bulldogs guard Alex Furr went down clutching her left knee with 9:26 left in the game. The junior, who has torn her left ACL twice in recent years, returned later to score a basket.
BYU 72, NORTH CAROLINA ST. 57
LOS ANGELES -- Lexi Eaton scored 25 points, Jennifer Hamson finished one block shy of a triple-double and 12th-seeded BYU upset No. 5 North Carolina State, 72-57.
The Cougars (27-6) will face fourth-seeded Nebraska in the second round on Monday at Pauley Pavilion on UCLA's campus.
Hamson, the West Coast Conference Player of the Year, finished with 12 points and tied her career-highs with 19 rebounds and nine blocks.
Kylie Maeda added 14 points and Morgan Bradley has 13 for BYU, which picked up its 11th win in 12 games and its first tournament win since 2006.
Miah Spencer scored 16 points to lead the Wolfpack (25-8), who lost in the first round for the fourth time in their last five tournament appearances.
NOTRE DAME REGIONAL
N. DAME 93, ROBERT MORRIS 42
TOLEDO -- Michaela Mabrey scored 11 of her 16 points in the first half, and top-seeded Notre Dame breezed to a victory in its NCAA tournament opener against 16th-seeded Robert Morris.
Jewell Loyd and Natalie Achonwa added 15 points each for the unbeaten Fighting Irish, who are trying for their fourth straight Final Four appearance. Notre Dame (33-0) is a No. 1 seed for the third straight season.
The Irish will take on ninth-seeded Arizona State in the second round Monday.
Robert Morris (21-12) shot 27 percent from the field. Greek star Artemis Spanou, one of the top players in Northeast Conference history, was held to seven points and attempted only four shots from the field.
ARIZONA ST. 69, VANDERBILT 61
TOLEDO -- Katie Hempen scored 16 points, and ninth-seeded Arizona State handed eighth-seeded Vanderbilt a rare first-round loss in the NCAA tournament, holding off the Commodores.
The Sun Devils (23-9) shot 62 percent to win this matchup between two teams who struggled coming into this tournament. Arizona State had lost three in a row and six of eight. Vanderbilt's loss Saturday was its fifth straight and 10th in 12 games.
Marqu'es Webb scored 18 points for the Commodores (18-13), overpowering Arizona State inside, and senior star Christina Foggie added 16.
Deja Mann, Arizona State's leading scorer, did not attempt a shot in the first half and finished with only eight points -- but the Sun Devils had enough balance and depth.
KENTUCKY 106, WRIGHT STATE 60
LEXINGTON, Ky. -- Jennifer O'Neill scored 21 points, Samarie Walker added 12 with 14 rebounds and third-seeded Kentucky crushed No. 14 Wright State.
Hosting their first NCAA women's postseason game, the Wildcats (25-8) used home court and other advantages to overwhelm an undersized Raiders squad making their tournament debut. Kentucky shot 55 percent from the field, grabbed a school-record 67 rebounds and recorded a season-high 12 blocks.
The Wildcats will face No. 6 Syracuse in Monday night's second round of the Notre Dame Regional.
Ivory James had 16 points to lead Wright State (26-9).
SYRACUSE 59, CHATTANOOGA 53
LEXINGTON, Ky. -- Syracuse guard Brittney Sykes had 13 points and 12 rebounds before injuring her right knee midway through the second half as the sixth-seeded Orange beat Chattanooga for its first-ever NCAA tournament win.
Leading 40-36 with 12:46 remaining, Sykes drove to the basket before grabbing her leg and screaming. The Orange stayed strong without their top scorer, using a 52-36 rebounding edge to stretch the lead to 10 with 2:33 left before withstanding a late Chattanooga rally featuring three 3-pointers from Taylor Hall.
Syracuse (23-9) hit 24 of 31 free throws to seal the victory that also snapped Chattanooga's 25-game winning streak. Shakeya Leary made 7 of 8 from the line to finish with 15 points.
Brianna Butler was just 2 of 11 from the floor but hit 9 of 10 free throws for 13 points.
Chattanooga (29-4) hit just 4 of 14 from the foul line. Hall led the Lady Mocs with 19 points and 10 rebounds.
OKLAHOMA STATE 61,
FLORIDA GULF COAST 60, OT
WEST LAFAYETTE, Ind. -- Tiffany Bias' driving layup with 41 seconds remaining in overtime lifted No. 5 seed Oklahoma State to a victory over No. 12 seed Florida Gulf Coast.
The Cowgirls (24-8) will play either No. 4 seed Purdue or 13th-seeded Akron in the second round on Monday night.
The teams traded the lead in OT before Bias' layup. Florida Gulf Coast (26-8) missed a shot with that would have given the Eagles the lead. Oklahoma State was fouled with 3 seconds left, but Liz Donohoe missed the free throw. Florida Gulf Coast had a chance, but Brittney Martin stole the inbounds pass with a second left. She too was fouled and missed her free throw giving the Eagles one final chance, but they couldn't get a shot off.
CALIFORNIA 64, FORDHAM 63
WACO, Texas -- Brittany Boyd scored 22 points, including the game-winning jumper with 14 seconds left, and California survived for a 64-63 victory over feisty Fordham.
California (22-9), a Final Four team last season, held on when Erin Rooney's final shot for the Rams came up short.
There were eight ties and nine lead changes in the second half, including lead changing three times in the final 32 seconds.
Rooney had 17 points, 10 rebounds and five assists for Fordham (25-8), the Atlantic 10 tournament champ playing in its first NCAA tourney in 20 years.
After Rooney drove for a layup against Boyd with 19 seconds left, Boyd responded with a jumper at the other end before the Rams called timeout to set up a final play for Rooney.
Boyd also had 10 assists and six rebounds.
BAYLOR 87, WESTERN KENTUCKY 74
WACO, Texas -- Nina Davis had 32 points and 10 rebounds in her NCAA tournament and Odyssey Sims scored 31 points for Baylor in an 87-74 first-round victory over Western Kentucky on Saturday night.
With coach Kim Mulkey watching the game from her house while serving an NCAA suspension, the Lady Bears (30-4) advanced to play California after the big scoring games by Big 12's top freshman and their most-experienced player.
Western Kentucky (24-9) led only once, but that was for less than a half-minute in the first half before Davis and Sims combined for all the Baylor points in a 14-4 run.
TENN. 70, NORTHWESTERN ST. 46
KNOXVILLE, Tenn. -- Isabelle Harrison scored 12 points and sparked a game-changing 12-0 run as No. 1 seed Tennessee withstood an ailing head coach and a lethargic first-half performance to beat Northwestern State, 70-46.
Tennessee coach Holly Warlick missed the Lady Vols' morning shootaround with what school officials described as a case of food poisoning. Warlick rejoined her team for the game, but she had an IV port in her left hand during the first half and sat on an orange stool while assistant coach Kyra Elzy stood and shouted instructions.
Warlick stood and was much more animated in the second half as Tennessee pulled away.
Northwestern State (21-13), seeking to become only the second No. 16 seed to beat a No. 1 seed, forced a 22-22 tie early in the second half before the Lady Vols (28-5) scored 12 straight points to seize control.
ST. JOHN'S 71, USC 68
KNOXVILLE, Tenn. -- Briana Brown sank a 3-pointer with four-tenths of a second left to give No. 8 seed St. John's a 71-68 victory over No. 9 seed Southern California.
Southern California guard Brianna Barrett's desperation shot at the buzzer from at least 35 feet away bounced off the backboard and front rim.
St. John's (23-10) plays a second-round game Monday against No. 1 seed Tennessee, which beat Northwestern State 70-46 in Saturday's other matchup at Thompson-Boling Arena.
Southern California (22-13) had a six-game winning streak snapped.
St. John's called a timeout with 25 seconds remaining to set up its final possession after a shot from Southern California's Cassie Harberts spun out with 31 seconds left. Keylantra Langley passed to Brown, who hit her shot from the baseline corner on the opposite end of the St. John's bench.
FLORIDA ST. 55, IOWA ST. 44
AMES, Iowa -- Natasha Howard had her school-record 15th double-double of the season with 10 points and 13 rebounds, and 10th-seeded Florida State defeated cold-shooting Iowa State, 55-44.
The Seminoles (21-11) won their 11th straight tournament opener since 1991, prevailing in a game in which turnovers outnumbered field goals 44-36. They'll play No. 2 seeded Stanford or No. 15 South Dakota on Monday night.
Cheetah Delgado had 10 points and six assists and Ivey Slaughter grabbed 13 rebounds for the Seminoles.
Hallie Christofferson scored 13 points, Brynn Williamson added 12 on four 3-pointers, and Jadda Buckey had 10 for the Cyclones (20-11).
Howard came in averaging 29.2 points in her previous nine games but didn't crack double figures until less than 4 minutes were left.
STANFORD 81, SOUTH DAKOTA 62
AMES, Iowa -- Chiney Ogwumike scored 23 points to become the Pac-12's career scoring leader, and Stanford used a couple big runs to pull away from 15th-seeded South Dakota and win 81-62 in the first round of the NCAA women's tournament Saturday night.
The Cardinal (30-3), seeded No. 2 in the regional they'll host next weekend, advanced to a Monday game against No. 10 Florida State.
Stanford kept all the Coyotes under wraps except Australian guard Nicole Seekamp, who made 9 of 13 shots and finished with 22 points. The loss by the Summit League's Coyotes (19-14) dropped No. 15 seeds to 0-82 all-time in first-round games.
