Stanford 60, Kansas 57

ST. LOUIS — Canadian Dwight Powell had 15 points and seven rebounds and No. 10 seed Stanford wrapped up its second straight upset at the free throw line, knocking off No. 2 Kansas 60-57 in the South Regional on Sunday.

Chasson Randle added 13 points, six steals and four assists for the Cardinal (23-12), who advanced to the round of 16 for the first time since 2008 — also their last NCAA appearance. They beat No. 7 seed New Mexico on Friday.

Canadian freshman Andrew Wiggins had just four points on 1-for-6 shooting with four turnovers in his final college game for Kansas (25-10). Wiggins, from Vaughan, Ont., is a likely NBA lottery pick and had averaged 28 points the previous four games.

Stanford will play 11th-seeded Dayton, which beat No. 3 Syracuse 55-53, in the round of 16 in Memphis, Tenn.

Canadian centre Stefan Nastic had 10 points and four rebounds for the Cardinal. Nastic, from Thornhill, Ont., also had one block over 31 minutes of playing time.

Kansas is the second No. 2 seed to be eliminated. Villanova lost 77-65 to seventh-seeded Connecticut in the East Regional.

Tarik Black had 18 points and six rebounds for the Jayhawks, but he fouled out with 5:25 to go. Conner Frankamp had 12 points on four 3-pointers, the last two in the final 23 seconds to make it close after Stanford had pulled ahead by seven.

Stanford was 9 for 12 at the free throw line over the final 2:04 and needed all those points. Frankamp's second 3-pointer narrowed the gap to 59-57 with 14.9 seconds left.

Anthony Brown hit just one of two free throws with 12.9 seconds and Frankamp banged a third 3-point attempt off the glass near the buzzer in a bid to tie it.

Kansas went to a full-court press down five points with about 11 minutes to play and forced five turnovers the next 6 minutes to tie it

Kansas had been 0 for 10 from 3-point range for the tournament, seven of the misses against Eastern Kentucky, before Frankamp connected with 3:34 to go in the half.

Frankamp hit another one just before the halftime buzzer off a turnover to put the Jayhawks up 24-22, their first lead of the game with both teams shooting just 32 per cent. They trailed most of the first half against Eastern Kentucky, too, before pulling away for an 80-69 victory.

Powell, from Toronto, hit his first shot on a drive after going 0 for 8 against New Mexico on Friday. He had 10 points before drawing his fourth foul early in the second half.

Kentucky 78, Wichita State 76

ST. LOUIS — Andrew Harrison scored 20 points, twin brother Aaron had 19 and Kentucky ended Wichita State's pursuit of perfection Sunday when Fred VanVleet's potential game-winning 3-pointer missed in a 78-76 victory in the NCAA tournament.

Julius Randle had 13 points and 10 rebounds, and James Young also had 13 points for the No. 8 seed Wildcats (26-10), who made a series of clutch free throws in the final minutes to hold off the top-seeded Shockers in arguably the most captivating game of a thrilling first weekend.

Kentucky will play in-state rival Louisville in the Sweet 16 on Friday in Indianapolis.

Cleanthony Early scored 31 points and Ron Baker had 20 for the Shockers (35-1), who hadn't lost since last year's Final Four.

Iowa State 85, North Carolina 83

SAN ANTONIO — DeAndre Kane drove for the game-winning layup with 1.6 seconds left and No. 3 seed Iowa State beat North Carolina 85-83 on Sunday, advancing to the Sweet 16 for the first time since 2000.

The Cyclones (28-7) head to Madison Square Garden next week to face No. 7 seed Connecticut in the East Regional semifinals.

The Tar Heels (24-10) are gone in the NCAA tournament's opening weekend for the first time in consecutive seasons under coach Roy Williams.

North Carolina's Nate Britt raced the ball up court after Kane's basket, but time expired before he could reach halfcourt and call a timeout. Officials huddled for several minutes reviewing clock replays before ruling the game was over.

Tennessee 83, Mercer 63

RALEIGH, N.C. — Tennessee came to Tobacco Road and turned it into "Raleigh Top."

Jarnell Stokes had 17 points and a career-high-tying 18 rebounds, and the Volunteers denied Mercer a second straight upset in the NCAA tournament by routing the Bears 83-63 on Sunday night.

Josh Richardson had a career-high 26 points and Antonio Barton had 18 for the 11th-seeded Vols (24-12), who outrebounded Mercer 41-19 and kept the Southeastern Conference perfect in the tournament.

They joined Florida and Kentucky in the round of 16 — the first time three SEC teams made it that far since 2007.

Tennessee will face second-seeded Michigan (27-8) in a Midwest Regional semifinal Friday night in Indianapolis.

Stokes broke his 2-day-old school tournament record for rebounds.

Langston Hall had 15 points to lead the 14th-seeded Bears (27-9). They knocked off Duke in the signature upset of the tournament but couldn't answer Tennessee's size.

UCLA 77, Stephen F. Austin 60

SAN DIEGO — Jordan Adams scored 19 points and UCLA beat Stephen F. Austin 77-60 on Sunday to reach the Sweet 16 of the NCAA tournament for the first time since 2008.

The fourth-seeded Bruins (27-8) will play Florida, the tournament's overall top seed, in the South Regional semifinals on Thursday in Memphis. First-year coach Steve Alford has won as many NCAA tournament games in three days as the Bruins had in the previous five seasons combined.

Alford replaced Ben Howland, who was fired a year ago after the Bruins lost to Minnesota in their NCAA tournament opener. This is UCLA's first trip to the regionals since Howland got the Bruins to their third straight Final Four in 2008.

Stephen F. Austin (32-2), the No. 12 seed, had its 29-game winning streak snapped. The Lumberjacks hadn't lost in exactly four months.

Baylor 85, Creighton 55

SAN ANTONIO — Isaiah Austin and Brady Heslip each scored 17 points and Baylor shut down Creighton's Doug McDermott with suffocating defence, ending the career of the one of the most prolific scorers in college history with an 85-55 win Sunday night in the NCAA tournament West Regional.

Baylor's size and speed overwhelmed the third-seeded Bluejays (27-8) and their national scoring leader, earning a third trip to the Sweet 16 since 2010.

McDermott, who averaged 27 points this season, finished with 15 but had just three in the first half as Baylor built a 20-point lead. McDermott ranks fifth on the NCAA career scoring list.

No. 6 seed Baylor (26-11) had five players score in double figures and shot 64 per cent in one of the dominant performances of the NCAA tournament.

Virginia 78, Memphis 60

RALEIGH, N.C. — Joe Harris scored 16 points and top-seeded Virginia shot 56 per cent to beat Memphis 78-60 on Sunday night, earning its first trip to the NCAA tournament round of 16 in nearly two decades.

Anthony Gill added 13 points for the Cavaliers (30-6), who turned in a dominating performance while controlling the tempo and shutting down the eighth-seeded Tigers (24-10) at nearly every turn.

Virginia led by 15 at halftime and pushed that to 27 points late, picking right up where it left off in its strong finish to Friday's tournament-opening win against Coastal Carolina.

In what has already been the program's most successful season in decades, Virginia added another milestone: its first regional semifinal appearance since making it to a regional final in 1995. And the Cavaliers, carrying a No. 1 seed for the first time since the days of Ralph Sampson, look ready to go even farther.

Arizona 84, Gonzaga 61

SAN DIEGO — Aaron Gordon and Rondae Hollis-Jefferson scored 18 points each, and Arizona looked every bit the No. 1 seed in the West while blowing out Gonzaga 84-61 on Sunday.

After four days of upsets and buzzer beaters, Arizona (32-4) closed out the NCAA tournament's first weekend with a display of domination.

The Wildcats harassed the eighth-seeded Bulldogs (29-7) into 21 turnovers — 15 on steals — that led to 26 points.

Arizona led by 21 in the first half and continued to work over Gonzaga to earn its third trip to the Sweet 16 in four years.

Up next for the Wildcats is a trip up the coast to Anaheim, where they'll meet San Diego State, a team they beat in this same arena early in the season.

Przemek Karnowski scored 14 points and Kevin Pangos of Landing, Ont., added 12 for Gonzaga.
