All three U.S. entrants qualified for the men's shot put final Friday, with 34-year-old Reese Hoffa of Augusta topping everyone with a best heave of 70 feet, 1 inch (21.36 meters).
Hoffa owns four world championships medals but is seeking his first piece of hardware at an Olympics; he was seventh at Beijing in 2008, for example. Hoffa is a former Lakeside and University of Georgia star.
Next-best Friday morning was world champion David Storl of Germany at 69-4¾ (21.15), followed by reigning Olympic champion Tomasz Majewski of Poland at 69-0 (21.03).
Also qualifying for this afternoon's final: Ryan Whiting of Harrisburg, Pa., and Christian Cantwell, of Eldon, Mo.
