Lebron James scored 23 points and grabbed eight rebounds to lift the Cleveland Cavaliers past the Milwaukee Bucks 91-73.

The win secures a post-season spot for Cleveland, making them the first team to do so this season. This is a first in the franchise’s history.

Mo Williams contributed 15 points for the Cavs, who are now 27-1 in their home court this season. Zydrunas Ilgauskas had 14 points and five rebounds, while Delonte West had a career-high eight steals.

Cleveland is now the top seed in the Eastern Conference. They will be playing the Boston Celtics come Friday.

Milwaukee was led by Richard Jefferson, who had a game-high 29 points. He had help from Ramon Sessions, who added 10 points, eight assists, and six rebounds. The Bucks have now lost six of their last eight games.
