Van Horn scores 28

The 100-80 victory wasNew York's most lopsided this season.
MIAMI (AP) -- Keith Van Horn scored 28 points and point guard Frank Williams moved into the starting lineup, helping the New York Knicks to their most lopsided victory this season -- 100-80 over the Miami Heat on Saturday night.
The Knicks scored 13 of the game's first 15 points, then closed the third quarter with an 18-2 run to build their advantage to 83-59. Van Horn scored 17 points in the quarter, including all four of his 3-pointers.
Van Horn grabbed eight rebounds in 35 minutes and finished 4-for-6 from 3-point range. He was only 16-for-68 (.235) previously this season.
Williams, a second-year guard making his first NBA start, had 14 points -- including baskets in the final second of the second and third periods.
Hot shooting
Allan Houston added 15 points for New York, which shot 51 percent. The Knicks came into the game with the fourth-lowest scoring average in the NBA (87.9) and reached 100 points for just the third time. Their previous largest victory margin was 11.
The Heat had won three in a row, and at home they had won five straight. But they shot just 36 percent to disappoint a crowd of 16,500 -- Miami's largest this season.
Lamar Odom scored 25 points for the Heat. They were without rookie starting guard Dwyane Wade, who sprained his right wrist in Friday's victory at Washington. His status is day-to-day.
A jumper by Houston put the Knicks ahead 43-27. Williams scored New York's final seven points of the first half, including a buzzer-beating layup for a 52-42 lead.
The Heat missed their final eight shots in the third quarter. Van Horn sank back-to-back 3-point shots to put the Knicks up 74-57, and Williams made a 22-footer with four-tenths of a second left in the period.
