Mavs clamp down in third, lead Rockets

DALLAS -- The Dallas Mavericks' defensive momentum carried over from the final few minutes of the first half.

The Houston Rockets, red hot for most of the first half, suddenly look like a team without a proven go-to guy. They shot 5-of-22 from the floor in the third quarter, when the Mavs turned a four-point deficit into a nine-point lead.

Jason Kidd accepted the challenge and locked up Aaron Brooks, who had only three points in the quarter after going off for 19 in the first half. Erick Dampier almost singlehandedly made sure the Rockets didn't get any second-chance opportunities, grabbing eight rebounds in the quarter.
