Al­though the final dates of next sea­son's Grand Prix se­ries aren't expected to be finalized until lat­er this summer, USA Swimming would like to come back to Canham Natato­rium in the spring of 2012 -- pos­sibly late April -- if dates can be worked out with the Uni­versity of Michigan, said Bailey Weath­ers, exec­utive head coach of Club Wolver­ine.

The U.S. Olympic trials for the Lon­don Summer Games are June 25-July 2, 2012, in Om­aha, Neb.

The three-day Namesnik Grand Prix, named in hon­or of Eric Namesnik, the two-time Olympic silver medalist and Michigan graduate who died in a car accident 2006, concluded Sunday night.

Returning to Canham for the first time in four years, the event attracted capacity crowds of just under 1,000 fans for the finals the first two nights. More than 50 people who were wait­ing in line for tickets Sat­urday were turned away, Weath­ers said.

For­mer U-M men's swimming head coach Bob Bowman, who coaches Phelps, said he was im­pressed with the orga­ni­zation of the meet.

"Look at the crowds, it's been great," Bowman said.

Weath­ers said: "If it can work out, we'd love to have it again."

Weath­ers said dozens of vol­unteers from Club Wolver­ine helped run the meet. USA Swimming -- the sport's national governing body -- was also pleased with Dom­ino's sponsor­ship of "Project Detroit," a program that as­sisted youth swimmers from the city of Detroit to come to Ann Ar­bor over the week­end to at­tend the com­pe­tition, Weath­ers said.
