Campbell, who also competed in the 2008 Olympics in Beijing, jumped up and down in the circle and squealed for joy after her long throw. At 71.80 meters, it just bested Bingson's throw of 71.78 meters.
"I knew as soon as I let it go and I hit it that it was going to be a good one," she said.
Keelin Godsey, who was vying to become the first transgender to make the U.S. team, finished fifth at 231-3. Godsey was born a woman but identifies as a man.

Coach K: LeBron on team
Mike Krzyzewski said Thursday he expected LeBron James to play for the U.S. Olympic team.
Speaking less than two weeks before the candidates for the Olympic team begin practice in Las Vegas, Krzyzewski said matter-of-factly: "I know LeBron will play."
James, whose Miami Heat are battling the Oklahoma City Thunder in the NBA Finals, was part of the Krzyzewski-led team that won Olympic gold at the Beijing Games four years ago.
Injuries, including to Dwight Howard, Derrick Rose, Chauncey Billups, and LaMarcus Aldridge, have thinned the pool of players available for the U.S. roster.
Furthermore, the combination of the condensed NBA season, late playoffs, and an earlier Olympics has eliminated the buffer between the events and means "you're going to have a mentally different team and a physically different team," Krzyzewski said.
