The Suns are closer to completing their training camp roster, turning their focus to free-agent big men Esteban Batista, Brian Skinner and Vitaly Potapenko and inviting free-agent swingmen Richie Frahm and Rawle Marshall to camp.

Skinner worked out for the Suns on Thursday with a group that included some Suns players and free agents such as Maurice Taylor, Frahm and Marshall.

Assuming they don't get a surprise call from veteran free agent P.J. Brown, the Suns are considering adding two big men to the Oct. 2-7 camp in Tucson. The Suns, who must add at least one player to their roster, have competition on all three free-agent big men.

But Skinner has not worked out for another team.

"This is the top of my list," he said. "It's a championship ballclub."
