Darius Bazley kicked the ball to Justin Jackson at the top of the arc, and Jackson rattled in a dagger 3-pointer with 14 seconds left.
Jackson’s shot gave the Thunder a five-point cushion in its 114-109 win against the Bucks on Sunday night at Chesapeake Energy Arena.
Jackson was in both the closing and starting lineup.
The fourth-year forward started in place of Hamidou Diallo, who had started five of the last six games. Diallo shot just 3-of-16 Sunday night off the bench, but he tied his career high with 13 rebounds.
Jackson followed a 20-point game Friday with a season-high 22 points Sunday.
