Diverse line in G League win
GMemphis Hustle   G League (Grizzlies)
December 28, 2025
Mashack totaled 18 points (7-16 FG, 2-4 3Pt, 1-1 FT), 10 assists, four rebounds, four steals and two blocks across 37 minutes in Saturday's 117-116 G League win over the Valley Suns.
ANALYSIS
Mashack was the only player in Saturday's game with double-digit assists, leading to his second consecutive G League double-double. The 18 points were also a new season-high mark for him. While he's under a two-way deal with the Grizzlies since Nov. 16, Mashack has appeared six times off the bench for the NBA squad and continues to see most of his action for the G League affiliate.
