The Spartans extended their six-point halftime lead and were able to pull away in the second half and led by as many as 21 points. In an obvious attempt to reduce fatigue, Winston only played 22 minutes in the game and Tom Izzo lifted MSU's starters with two minutes remaining in the game. A late surge by the Buckeyes narrowed the lead, but MSU held on for a 77–70 win. The win marked the 600th career victory for Izzo, all at Michigan State.
 The following day, the Spartans faced off against Wisconsin, who MSU had defeated in Madison earlier in the season. Michigan State jumped out to a 18–4 lead within the first six minutes and never trailed in the game. Wisconsin kept the game within shouting distance for most of the game, but MSU pulled out the win 67–55. Cassius Winston led the Spartans with 21 points while Xavier Tillman added 17 points. Nick Ward again did not start, but played 11 minutes. He was saddled with foul trouble through most of the game and only scored two points. Winston injured his toe partway through the game and again saw his minutes restricted, playing only 28. The win sent MSU to the championship game of the Big Ten tournament.
 On Selection Sunday, the Spartans squared off with Michigan for the third time in only two weeks, this time for the tournament championship. MSU, who won the previous two games against the Wolverines, started well, jumping out to a 17–11 lead halfway through the first half. However, Spartan guard Kyle Ahrens went down hard on his ankle while coming down with a rebound in the first half and was taken out on a stretcher with an air cast on his leg. Following the injury, Michigan finished the half outscoring the Spartans 10–6, giving them a 31–23 lead at the half. The Wolverines came out hot in the second half, causing the Spartans to fall behind 39–26 in the early going. The Spartans were able to dig deep and complete a 22–9 run, tying the game at 48. MSU trailed the Wolverines by five with just over two minutes remaining, but a Matt McQuaid three pointer and a Cassius Winston assist to Xavier Tillman tied the score at 60 with 1:20 left in the game. A missed Zavier Simpson three-pointer led to a Winston lay up and a Spartans' lead at 62–60 with 29 seconds left. The MSU defense forced Michigan into bad shot attempts and MSU finished by making three of four free throws to give them the 65–60 win. MSU finished the game on a 10–0 run to earn their first Big Ten tournament title since 2016. The win was the school's sixth tournament championship, which leads the Big Ten. The win also completed a three-game season sweep of in-state rival Michigan.
 Despite winning the Big Ten regular season and tournament championships, MSU did not receive a No. 1 seed in the NCAA tournament. Instead, the Spartans received the No. 2 seed in the East Region. In the first round, they struggled against No. 15-seeded Bradley, and trailed with only four minutes left in the game. However, helped by a season-high 25-for-26 from the free throw line, the Spartans pulled away for the 76–65 win. Kenny Goins struggled in the game, making only one of 10 shots and missing all seven three-point attempts. Cassius Winston led the way for the Spartans, scoring 26 points while Xavier Tillman added 16. The win moved MSU to the second round to face Big Ten foe Minnesota.
 In the earliest tournament meeting of Big Ten teams since the field had expanded to 64, the Spartans throttled Minnesota. MSU shot over 57% from the field while limiting the Gophers to 30%. MSU dominated Minnesota on the glass, out-rebounding the Gophers 45–19. Xavier Tillman led a balanced scoring attack for MSU with 14 points while Cassius Winston added 13. The Spartans blew out Minnesota 70–50 to advance to the Sweet Sixteen for the first time since 2015, the longest Sweet Sixteen drought for the Spartans under Tom Izzo.
 In the Sweet Sixteen, MSU faced No. 3-seeded LSU. The Spartans dominated for a second consecutive game, jumping out to an early 8–0 lead, and never trailed in the game. Freshmen Gabe Brown (15 points) and Aaron Henry (20 points) each had career-highs in points as the Spartans ran away from the Tigers to an 80–63 victory. Cassius Winston added 17 points in the win as MSU led for the whole game. The win moved MSU to the Elite Eight for the first time since 2015, where they would face the No. 1 seed in the South region and overall No. 1 seed in the tournament, Duke.
 In the Elite Eight, Izzo faced Duke Coach Mike Krzyzewski for the 13th time. Izzo had only beaten "Coach K" one time with a record of 1–11 against him coming in to this game. Cassius Winston tallied a double-double with 20 points and 10 assists while Xavier Tillman added 19 points and nine rebounds. However, MSU, who led at the half, trailed by one with less than a minute remaining. Kenny Goins hit a three-pointer with 34 seconds remaining in regulation to give Michigan State the lead. Duke had an opportunity to tie the game at the free throw line with five seconds remaining after Tillman was called for his fourth foul, however Duke freshman R.J. Barrett missed the first of two free throws and inadvertently made the second one. On the ensuing out-of-bounds play, Tillman passed the ball to Winston who sprinted ahead of Duke defenders and ran out the clock to secure the victory 68–67 victory. The Spartans snapped a seven-game losing streak against Duke and advanced to the Final Four for the first time since 2015.  Winston was named the East regional's Most Outstanding Player.
 The Spartans faced No. 3-seeded Texas Tech in the Final Four on April 6, 2019. The visit marked the school's 10th Final Four and eighth under Tom Izzo. Texas Tech limited the Spartans to just under 32% shooting from the field and took a two-point lead in to halftime. The Spartans continued to struggle with the Red Raider defense in the second half, trailing throughout the half. Cassius Winston hit only four of his 16 shots and notched only two assists. Texas Tech moved the lead to 13 points with less than 10 minutes remaining, but the Spartans fought back to within one point. However, MSU could not complete the comeback and lost 61–51 ending their Tournament run.
