Semifinal #1: Team 9 - 70, Team 8 - 62
The first semifinal saw Team 9 (#1 seed) and Team 8 (#4 seed) engage in a showdown of two of the league's best teams in front of a raucous crown inside the K1 gym. Team 8 jumped out to an early lead, thanks to the sparkling first-half play of Bobby Crivokapich, who connected on all five of his three-point attempts. After 20 exciting minutes, with the two teams exchanging blows, Team 8 would lead Team 9 by a score of 38-35 at halftime. The second half would be a different story though, as Team 9 would lock things down defensively. Team 9 would hold Team 8 to just 24 points in the second half on their way to a 70-62 win. While Red Binion and Tyree Mosley played extremely well on the offensive end of the court, scoring 22 points and 21 points respectively, it was Team 9's ability to keep the ball out of the hands of Team 8's Seth Johnson that proved to be the difference. For Johnson, who finished one vote shy of player-of-the-year honors, he came into the game averaging 20 points per game and 17 rebounds. He was held to just eight points and nine rebounds in this contest, despite a sizeable height advantage against the smaller Team 9. Quon Shaw also added 11 points for Team 9, while Ronnie Jackson had eight points. Team 8's Andre Robertson Jr. had 12 points, while Gerald Duckworth had 11 points. Crivokapich led the way with 24 points. Team 8 finishes the season at 6-4, and will be one of the league's favorites come the Fall 2021 league.

Semifinal #2: Team 1 - 64, Team 5 - 53
The second semifinal saw Team 1 (#2 seed) and Team 5 (#6 seed) square off in an intriguing battle of experience vs. youth. Team 1, who came into the game with a record of 8-1, only had one single-digit win all season, and that came against Team 5 back on March 28th. Unfortunately for Team 5, a short bench on Sunday would prove to be the difference maker, as they were unable to keep pace with Team 1 in a 64-53 loss. Team 5's Terrell Hendrix, who was voted by the coaches to the first-team ballot, picked up his fourth personal foul in the final minute of the first half, in a deflating moment for Team 5. Although Team 1 had built a 37-22 lead at the half, Team 5 battled back and would cut the lead to just seven points in the second half. However, with only two players on the bench, Team 5 was forced to play its starters for signifcant minutes, and Hendrix would pick up that inevitable fifth foul with about ten minutes remaining in the game. This would be the kill shot for Team 5, as Team 1 ran away with it from there, taking advantage of multiple technical fouls and a much deeper bench. Team 1 had four players in double figures, as Chris Green led the way with 16 points. John Martin had 11 points, while Dennis Koger and Trey Johnson each had 10 points. For Team 5, Hendrix and Jamari Washington each had 14 points, while ke'Sean Williams and Trey Anthony had seven points. Another key stat was Team 1's advantage on the glass, as they secured 36 total rebounds compared to just 21 for Team 5. Without center Lamarius Lillard, Team 5's Demarcus Macon was tasked with holding off the three-man interior attack of Martin, Koger, and Johnson. Team 5 finishes their season at 4-6, but will take a lot of confidence into the fall, having made the tournament's final four.
