Tom Walsh will keep his American rivals close in the lead-up to the Rio Olympics
The world indoor shot put champion will train with US throwers Jordan Clarke, Ryan Whiting and Reese Hoffa over the next couple of months.
Walsh says he's been unable to find time to train with Valerie Adams this time around.
He says he learnt a lot from Adams and she's a reason why he's the thrower he is today.
Walsh will be based in Arizona for the next fortnight before the next Diamond League meeting in Oregon.
