The home team has won each of the first five games of the first-round series between the Boston Celtics and the Milwaukee Bucks, a trend the Bucks hope to maintain when they host a do-or-die Game 6 on Thursday. The second-seeded Celtics took a 3-2 series lead with a 92-87 win at home Tuesday night, moving to within a victory of a second-round matchup with the Philadelphia 76ers.
