CHARLOTTE, N.C. — JaVale McGee scored 22 points and had 10 rebounds as the Washington Wizards defeated the Charlotte Bobcats for the second time in a week, 102-99 on Saturday night.

The matchup between two teams tied for the fewest wins in the NBA came down to the final shot, but Matt Carroll's 3-point attempt at the buzzer fell short.

McGee had a chance to seal the game with less than 6 seconds to go, but missed two foul shots. But that was about all McGee didn't do right, as shot 9 of 14 from the field. Like many others this season, McGee exposed Charlotte's poor interior defense, using an effective hook shot in the lane.

John Wall added 13 points and 10 assists for the Wizards (4-16).

Kemba Walker became only the third Bobcats (3-18) player to register a triple-double, recording 20 points, 10 rebounds and 11 assists.
