No. 3 these days, some 70 years after Jimmie Foxx last wore it, belongs to Mike Aviles. He may not be Pete Runnels, Walt Dropo or Gary Geiger, but if he wears a single-digit number, he's got a better than even chance to play with some regularity. That very thought probably passes through the mind of Jose Iglesias each time his arms pass through the sleeves of the Red Sox uniform top that carries No. 76 on its back, his uniform.
