The Suns are closing in on a trade that would put them in the top 10 of Thursday's draft, according to David Griffin, Phoenix's senior vice president of basketball operations.

The increasing chances prompted Florida's Corey Brewer, Joakim Noah and Georgetown's Jeff Green to agree to work out Tuesday in Phoenix with a fourth mystery player of top-10 caliber.

There are ongoing talks with a few teams in the top 10 but one dialogue is "much hotter," Griffin said.

To make a deal, the Suns would likely give up some combination of their 24th and 29th picks this year and the draft pick of Atlanta's that they own for next year.
