Mascari agreed to an Exhibit 10 contract with the Knicks on Tuesday.
Mascari is set to compete for a spot on New York's regular-season roster in training camp. However, the organization now owns his G League rights, so Mascari could be waived before camp begins. Over 48 appearances with the G League's Stockton Kings in 2025-26, he averaged 8.5 points, 2.9 rebounds and 0.8 assists while shooting 42.5 percent from beyond the arc across 19.6 minutes per contest.
