Hall of Fame Michigan State head coach Tom Izzo earned his 15th trip to the Sweet 16 after eliminating two-seed Marquette 69-60 in Sunday's second round of the NCAA Tournament.

The Spartans rode a 23-point performance from senior point guard Tyson Walker, while Joey Hauser – brother of Boston Celtics wing Sam Hauser – collected 14 points and 10 rebounds.

As well as pulling into a tie for the sixth-most Sweet 16 appearances in head coaching history, Izzo also claimed the record for the most ever NCAA Tournament wins as the lower seed, with this his 16th.

He is one more Sweet 16 trip away from tying Louisville legend Denny Crum for the fifth-most, with only North Carolina's Roy Williams (19), Syracuse's Jim Boeheim (20), Michael Jordan's North Carolina coach Dean Smith (21) and Duke's Mike Krzyzewski (26) having more.

The seven-seed Spartans will next face three-seed Kansas State after they won the battle of the Wildcats 75-69 against six-seed Kentucky.

Reigning National Player of the Year Oscar Tshiebwe was monstrous with 25 points and 18 rebounds, while projected first-round draft pick Cason Wallace impressed with 21 points (nine-of-11 shooting), nine rebounds, four assists and two steals.

But their performances were not enough to lift Kentucky to the victory, as diminutive five-foot-eight point guard Markquis Nowell dropped a game-high 27 points and nine assists to carry Kansas State through.

Following his massive 28-point, 13-rebound showing in his side's opening-round win, Connecticut Huskies center Adama Sonogo starred again with 24 points (11-of-16 shooting) and eight rebounds in a 70-55 win over the Saint Mary's Gaels.

After Marquette, the top seed to fall Sunday was the three-seed Baylor Bears. Despite 30 points from Baylor guard L.J. Cryer, the Creighton Bluejays received a game-winning 30 points from Ryan Nembhard in the 85-76 triumph.

Nembhard is the younger brother of Andrew, who has been a rookie standout for the Indiana Pacers this season.

Following their stunning upset of one-seed Purdue, where they became the second 16-seed to ever advance past the first round, the Fairleigh Dickinson Knights were sent packing 78-70 by the nine-seed Florida Atlantic Owls.

Three-seed Xavier were in control throughout their 84-73 win against Pittsburgh, five-seed Miami prevailed 85-69 over four-seed Indiana, and four-seed Gonzaga sent six-seed TCU home 84-81.
