Moments before scoring the first touchdown of his six-year NFL career, defensive end Kenny Holmes had a premonition.

“He said, ‘I feel I’m gonna get one, and I don’t get this feeling too often,’ ” Michael Strahan recalled Holmes saying. “He scooped up the ball and I’m running down the field trying to block for him and I’m thinking to myself, ‘You got to be kidding me.’ “

No kidding. With the Giants leading 7-0 in the first quarter yesterday, the Cowboys on fourth-and-3 on the Giants 36-yard line tried for the first down. They got misery instead. Middle linebacker Micheal Barrow stormed in on QB Chad Hutchinson for a 14-yard sack and also forced a fumble that bounced out toward mid-field.

Barrow gave chase and had the inside track on the ball, but Holmes actually bumped Barrow out of the way.

“I was like he better score, he don’t block me out like he’s faster than me,” Barrow said, laughing.

Not only did Holmes get the ball, he made a sharp cut to his left, shifted the ball from his right arm to his left and showed surprising speed and moves in motoring 50 yards, pausing the final five as he sauntered into the end zone. It was 14-0 en route to the Giants’ 37-7 rout of the Cowboys.

“I saw the ball and was able to scoop it up and make some cuts in order to get into the end zone,” Holmes said. “To jump out two touchdowns on a team, it puts them in a slump.”

This was easy pickings for the Giants on defense. They were healthier than they’ve been in weeks, with Barrow, cornerbacks Will Peterson and Will Allen and linebacker Dhani Jones all returning from injuries. Peterson, back in the starting lineup after missing two games with a concussion, left late in the first quarter with a burner. Strahan, who has a strained neck, also left briefly but was able to return. Safety Shaun Williams left in the second quarter with back spasms and was replaced by Johnnie Harris, who came up with his first interception with the Giants. Williams was able to return and came up with a third-quarter interception.

As he sat out near the end of the rare blowout victory, Strahan watched as little-used Byron Frisch got two sacks against his former team.

“I was quite angry at Byron Frisch for getting two sacks,” Strahan said, “then he stole my little flex at the end.”
