SACRAMENTO — Beno Udrih scored 13 points and hit a 3-pointer at the buzzer to lead the Sacramento Kings to a two-point lead over the Lakers at halftime tonight. Kobe Bryant had 14 points to lead the Lakers, and Pau Gasol had 12 points. Lamar Odom scored nine points while starting in place of Ron Artest, who did not make the trip after suffering a concussion in a fall at his home Christmas night. The Lakers played with far more intensity and efficiency than during their dreary loss Friday to the Cleveland Cavaliers.
