As Kenyon Martin dogged Antoine Walker throughout Game 3 on Friday, he saw frustration flash like a blinking billboard across Walker's face.

Martin did not pause to consider that he had won the psychological duel over his Boston counterpart - yet.

"No," Martin said today, "you just want to keep it going."

He and the relentless Nets have a 3-0 lead over the Celtics in their four-of-seven-game Eastern Conference semifinal series entering Game 4 on Monday night in the Fleet Center.
