SAN ANTONIO (AP) ― Often the forgotten member of Miami’s “Big Three,” Chris Bosh stepped up with LeBron James and Dwyane Wade sitting out to get the Heat a big win and move closer to securing home-court advantage throughout the NBA playoffs.

Bosh scored 23 points, including the winning 3-pointer with 1.9 seconds remaining, and the Heat beat San Antonio 88-86 on Sunday night with James, Wade and Mario Chalmers watching from the locker room as they sat out with injuries.

“We are the defending champs no matter who we put out there,” Bosh said. “We are still the Miami Heat. We believe in ourselves. Each one of these guys is a professional. We played bigger roles in other cities but we came together and accepted lesser roles to win a championship here.”

Ray Allen added 14 points, Norris Cole had 13 and Mike Miller 12 for Miami (58-15), which swept the season series with San Antonio (55-18).
