Yao topped the game with 25 points and 10 rebounds but still
said he had problems with the Spurs' defense in Rockets' 88-81
defeat.
The Rockets played without Tracy McGrady, who could miss five
weeks with a back injury.
Alston scored 15. Luther Head added 13, and Keith Bogans had 11
for the Rockets.
The loss kept Houston winless in 10 games against Southwest
Division rivals.
