Chris Bosh

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. We can still tap into that.”

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). By earning the head-to-head tiebreaker with San Antonio, the Heat have a four-game cushion with nine remaining for the league’s best record…

Miami beat San Antonio 105-100 on Nov. 29 when the Spurs opted to rest Tim Duncan, Tony Parker, Manu Ginobili and Danny Green.

All but Ginobili (strained right hamstring) played Sunday.

Duncan had 17 points and 12 rebounds and Kawhi Leonard added 17 points and 11 rebounds for the Spurs, who had a seven-game home winning streak snapped. Green and Parker added 12 points apiece and Stephen Jackson had 11.
