Boston pulled away after another slow start, beating Charlotte 87-75 in Las Vegas by holding the Hornets below 20 points in each of the final three quarters.
Dillon Mitchell led the breakout with 24 points, 8 rebounds, 6 steals and 2 blocks, pairing his usual defensive activity with 2-of-5 shooting from 3-point range.
John Tonje added 17 points on 6-of-10 shooting and Milos Uzan posted 13 points with 6 assists, strengthening their cases for Boston's open two-way roster spots.
Amari Williams had a mixed outing despite 4 blocks, finishing with 6 points and 5 turnovers, while Hugo Gonzalez again contributed across the board but shot just 3-of-10.
Two games into Summer League, Boston's early focus is shifting from wins to player evaluation, with Mitchell's jumper and Uzan's playmaking emerging as key roster-development storylines.
