Their season ended following the cancellation of postseason tournaments due to the COVID-19 pandemic.

On January 5, in a game against rival Michigan, senior point guard Cassius Winston recorded nine assists to move his career total over 800 making him the first Big Ten basketball player to ever record more than 1,600 points and 800 assists in a career. On January 17, Winston recorded his 817th career assist moving him past Mateen Cleaves for the most assists in Big Ten history.

Cassius Winston was a consensus All-American for the second consecutive year, becoming only the second Spartan to become an All-American in more than one season.

With a win over Maryland on February 29, Tom Izzo earned his 300th career Big Ten win, leaving him 53 victories behind the all-time leader Bob Knight. The Spartans began the season as the preseason No. 1 in both the AP and Coaches polls for the first time in school history.

The win over Ohio State on March 15, 2019 marked Tom Izzo's 600th career win. The Tournament win marked the school's sixth tournament championship, the most in the Big Ten. As a result of the Tournament victory, the Spartans received the conference's automatic bid to the NCAA tournament as the No. 2 seed in the East Region.

In the regional semifinals, the Spartans defeated No. 3-seeded LSU to advance to the Elite Eight. There they defeated overall No. 1-seed Duke to advance to the school's 10th Final Four and eighth under head coach, Tom Izzo. In the National Semifinals, Michigan State lost to No. 3-seed Texas Tech.
