LAS VEGAS (FOX5) — The UNLV men’s basketball program has received a signed commitment from Sebastian Mack to join the Runnin’ Rebels for the 2026-27 season, head coach Josh Pastner announced Monday.
Mack, a 6-foot-3-inch, 195-pound guard originally from Chicago, played as a freshman and sophomore at UCLA from 2023-25 and this past season as a junior at Missouri. Prior to attending college, he played at Coronado High School in Henderson, Nevada.
“We are excited to welcome Sebastian to the Runnin’ Rebel family and to add another Vegas guy to our roster,” Pastner said. “He is a downhill scorer who puts a lot of pressure on the defense, and he has proven he is elite at getting to the free-throw line. He is a fierce competitor who plays with toughness and confidence, and his ability to attack in transition fits extremely well with how we want to play. We are looking forward to the impact he can make in our program.”
At Missouri during the 2025-26 season, Mack appeared in 18 games and made nine starts. He averaged 7.0 points and 1.3 rebounds per game, scoring a season-best 17 points against then-No. 20 Illinois. He scored in double figures six times in a seven-game stretch from Nov. 7 to Nov. 28.
In two seasons at UCLA, he appeared in 67 games with 31 starts and averaged 10.8 points per game. He helped UCLA earn a bid to the 2025 NCAA Tournament, advancing to the second round. He earned Pac-12 All-Freshman Team honors in 2023-24 after ranking third on the team in scoring (12.1), rebounds (3.6), and assists (52). He scored in double figures a total of 37 times during his two seasons in Westwood, including at least 20 points on seven occasions.
Coming out of high school in 2023, Mack ranked as the No. 53 recruit nationally by Rivals. He averaged 24.0 points, 6.0 rebounds, and 5.5 assists as a senior for the Cougars. He was named the Nevada Class 5A Offensive Player of the Year and also earned first-team All-Southern League honors.
Mack joins Terrance Ford Jr., Jeremy Foumena, Tyler Harris, Jackson Kiss, Cam Miles, Kota Suttle, MJ Thomas, and Dontrez Williams as incoming players to the Runnin’ Rebel program for the 2026-27 season.
COMMITTED RETURNING REBELS: Tyrin Jones and Issac Williamson have both committed to return to the program in 2026-27 after playing as freshmen in 2025-26. Jones was selected to the Mountain West’s All-Defensive Team and earned honorable mention All-MW honors. He averaged 11.9 points and 5.0 rebounds per game, while leading the league in blocks with 2.2 per contest. Williamson scored 8.6 points per game.
PASTNER ENTERING SECOND SEASON: The 2026-27 campaign will be the second for Josh Pastner as head coach of the Runnin’ Rebels. He led the program to the postseason in his first year at the helm, advancing to the second round of the NIT.
