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.
