SAN ANTONIO (AP) _ The Spurs' Twin Towers began to dominate in the second quarter Wednesday night and San Antonio built a 45-37 halftime lead over the New York Knicks in Game 1 of the NBA Finals.

Tim Duncan had 19 points and 10 rebounds and David Robinson scored 11 points as the Spurs overcame a spotty first quarter in which the Knicks grabbed an early physical edge.

The Knicks led 27-21 after the first quarter, but shot just 3-for-18 in the second. It was a quarter in which the Knicks' worst fears were realized _ foul trouble. Allan Houston, Marcus Camby and surprise starter Larry Johnson each had three fouls.

Duncan had a driving finger roll, another layup and an 18-footer, and Robinson got a huge bounce on a 16-foot jumper to highlight San Antonio's 14-2 run in the final 4:10 of the half.

Houston led New York with 14 points and Latrell Sprewell scored eight.

New York's 10 second-quarter points was one shy of the NBA playoff record set by Utah last year against the Chicago Bulls.

The Knicks pulled their latest trick when Johnson started after injuring his left knee in New York's clinching victory in Game 6 of the Eastern Conference finals. But Johnson fouled Robinson twice a span of nine seconds early in the game and went to the bench.

Johnson had three points in six minutes in the first half, picking up his third foul on a pushoff with 6:14 left in the second quarter.

George ``The Iceman'' Gervin, who led the Spurs from the ABA to the NBA and won three straight scoring titles from 1977-80, threw up the ceremonial first tip.
