MILWAUKEE, WI (WHBL) - The Bucks season is over after the Miami Heat recorded their first series sweep in the playoffs since LeBron James and Chris Bosh joined former Marquette star Dwyane Wade in Miami. But the Heat didn't need Wade's services in Game 4 of their first-round Eastern Conference playoff series Sunday at the BMO Harris Bradley Center. James led the way with 30 points, eight rebounds, seven assists and three steals as Miami took down the Bucks, 88-77, to post the franchise's fourth postseason series sweep. Former Bucks guard Ray Allen and Udonis Haslem added 16 and 13 points, respectively, for Miami, which swept a playoff series for the first time since the 2005 Eastern Conference Semifinals. Bosh tallied 10 points and four blocks. Wade sat out Sunday's playoff game to rest his bruised right knee. He averaged 13.7 points, 7.0 rebounds and 6.3 assists in the first three games of this series. The Heat will face either Chicago or Brooklyn in the next round. The Bulls lead that series by a 3-1 margin. Monta Ellis ended with 21 points and eight assists for the Bucks, who haven't won an opening-round playoff series since 2001. Mike Dunleavy and J.J. Redick donated 17 and 10 points, respectively.
