Texas Tech has extended its first-ever trip to the Final Four with a 61-51 victory over Michigan State in a national semifinal game. The Red Raiders now advance to the final game of the NCAA Tournament, Monday's men's national championship game against Virginia, to be held at US Bank Stadium in Minneapolis. It is slated to be a game that focuses heavily on defense, with the two defensive-minded teams battling for what would be a first-time championship for both programs. Texas Tech entered the national semifinals by allowing just 84 points per 100 possessions, a defensive efficiency score on KenPom that ranks as the best the advanced-stats site has tracked dating to 2002.

Both defenses were strong in the second half of their semifinals. Texas Tech allowed Michigan State to make 8 of 24 shots, while Auburn made just 9 of 26 shots against Virginia. The championship game will also be a matchup of the past two Associated Press men's national coaches of the year, with Texas Tech's Chris Beard winning this year's award and Virginia's Tony Bennett claiming it last season. In Saturday's semifinal, Texas Tech came out firing in the second half and held off a Spartans' rally on the back of fifth-year senior graduate transfer guard Matt Mooney's 22 points. Cassius Winston led Michigan State with 16 points but shot just 4 of 16 from the floor while being tracked most of the game by Mooney, who made 8 of 16 shots and 4 of 8 from 3-point range.

He finished with 10 points. Senior Matt McQuaid's bid to tie with a long 3-point attempt at the other end rattled in and out, and Culver made the first of two free throws. Texas Tech got the ball back with its fourth steal of the game on Michigan State's next possession, and Culver hit an uncontested trey from the top of the key, putting the Red Raiders up 58-51. Senior Norense Odiase made two free throws to seal it with 39.7 seconds left after the Spartans' Kenny Goins clanked a 3-point try. The Spartans stayed in the game at the free-throw line. Sophomore Xavier Tillman rattled in two after Winston connected on four consecutive shots from the stripe, and Michigan State whittled a 12-point deficit to five (52-47) with 5:38 remaining. The Spartans cut it to three with just over three minutes to play on freshman Aaron Henry's two makes, then made it 52-51 when Henry's slashing layup went in with 2:44 left.

Edwards drove hard from the left baseline and moved the ball from his right to left hand, putting it off the glass as he was fouled. On the next possession, Mooney connected on a 3-ball from the wing and after a Michigan State turnover, the senior transfer drilled another to stake Texas Tech to a 45-33 advantage, prompting a red-faced Tom Izzo to call timeout. Most of the damage was done while Culver watched from the bench with three fouls. Suffocating defense won the first half on either end and neither team could find its legs. Only 15 of 49 field-goal attempts went through, and Texas Tech led 23-21 at the break.
