MIAMI — Until Tuesday, the Heat did not have a single player definitively under contract for 2010-11. Now there are two.

Working in advance of the league's Oct. 31 deadline for such moves, the Heat on Tuesday picked up the 2010-11 rookie-scale options on the contracts of 2008 first-round pick Michael Beasley and 2007 first-round pick Daequan Cook.

Had the Heat failed to make such a move, each would have become an unrestricted free agent at the end of the season.

With both working on relatively low-cost contracts, the Heat, even with its desire to maximize its salary-cap space for 2010 free agency, decided to move forward.

Beasley, who will earn $4.6 million this season, his second in the league, is now guaranteed a $5 million salary in 2010-11.

Cook, who will earn $1.4 million this season, is now guaranteed $2.2 million for 2010-11.

"What they did this summer was terrific, the commitment they put in," coach Erik Spoelstra said after Tuesday's practice at AmericanAirlines Arena. "Daequan looks like a completely different player, and Michael has been great at two positions."

The two become the only players on the current roster locked into 2010-11 salaries.
