A pair of Adebayo free-throws cut it to 99-98 with 34.8 seconds remaining. Lowry’s foul off the SLOB put Kyle Kuzma — a 51.6 percent free-throw shooter (on 31 attempts) entering Saturday — at the charity stripe, though the 6-foot-10 forward sunk both.
Butler and Kuzma traded a pair of free throws — making it 103-100 with 12.4 seconds left. Butler’s contested 3-point attempt with a second remaining rimmed out. Time was added back onto the clock, so Kuzma went to the charity stripe for two more, missing both. Adebayo’s full court heave just missed, clinching Washington’s 11th victory of the season.
