Cook, a 6-foot-9, 250-pounder, signed the extension about 90 minutes before a 9 p.m. PST deadline, keeping him from becoming an unrestricted free agent next summer.

Cook had career-high totals of 81 games, 7.9 points and 3.4 rebounds last season ¡ª his third with the Lakers after they made him a first-round draft pick in 2003.

"I feel great being here in Los Angeles, being with an organization that's a great organization ¡ª one of the best in the NBA," he said. "We've got a great chemistry here, everybody fights for each other. We have a winning attitude."

The 25-year-old Cook said he was literally pulled out of the layup line before the game to sign the contract, which he said has a third-year player option.

"I had to make a decision. I made it about 25 minutes before the game," he said after scoring nine points in 15 minutes to help the Lakers beat the Suns 114-106.
