MIAMI – At times, it seems Ichiro is caught in some kind of bizarre time warp. His body, at age 42, is as lithe and limber as ever. “If I ever get a belly, I will retire,’’ he tells me, repeating a familiar refrain – but there’s little chance of that, despite Ichiro’s insistence, perhaps playful, that he now eats three cheeseburgers with fries for lunch on the road. I dare say he’ll have a flat stomach at 52, 72 and 92.
