Miami Heat scorches Spurs to close on NBA's best record

The Miami Heat strengthened its grip on the NBA's best record - and home-court advantage throughout the playoffs -- by beating their nearest rivals, the San Antonio Spurs, 88-86 on Sunday thanks to Chris Bosh's 3-pointer with 1.9 seconds remaining.

The Heat holds the head-to-head tiebreaker against San Antonio, meaning they effectively have a four-game cushion over the Spurs with nine to play. In other games, New York closed in on its first Atlantic Division title in 19 years by beating Boston, and Chicago beat Detroit by the narrowest of margins to make it 18 straight wins over the Pistons.

Miami's Bosh scored 23 points, including the winning 3-pointer, as Miami scraped home with LeBron James, Dwyane Wade and Mario Chalmers all sitting out due to injuries.

Bosh finished 3 for 5 on 3s, including the final shot from straightaway in the closing seconds. He let out a loud yell after making the shot and celebrated with teammates when Tony Parker missed his jump shot as the buzzer sounded.

Ray Allen had 14 points for Miami while Tim Duncan had 17 points and 12 rebounds for the Spurs, who had won their previous seven home games.

New York's Carmelo Anthony had 24 points and 10 rebounds, and the Knicks extended their winning streak to eight games by beating the Boston Celtics 108-89. The Knicks beat the Celtics for the second time this week and won the season series for the first time since 2003-04. New York climbed back into a tie with Indiana in the race for the No. 2 seed in the Eastern Conference, which would currently mean a playoff meeting with the Celtics.
