The pair saw the Cavs defeat the Bucks, 101-98, thanks, in part, to clutch free-throw shooting by Mo Williams.
Williams, who scored 21 points, made four free throws in the final 12.8 seconds. LeBron James scored 23 for the Cavs, who have won 10 of their past 11.
John Salmons scored 28 for the Bucks.
Before the game, James said he will "probably not play" for Team USA in this summer's world championships.
James, a captain on the U.S. team that won a gold medal at the Beijing Olympics in 2008, said he may be too busy this summer to play for the national team.
