The Latest on the Olympics ahead of the Rio Games (all times local):
Madison Kennedy has qualified fastest in the 50-meter freestyle at the U.S. Olympic swimming trials.
Already the top-ranked American in the event, the 28-year-old sprinter from Avon, Connecticut, swam 24.52 seconds in the preliminaries Saturday in Omaha, Nebraska.
Simone Manuel was second quickest in 24.57, followed by Abbey Weitzel in 24.58 and Olivia Smoliga in 24.78.
Also advancing to the evening semifinals are Dana Vollmer, Amanda Weir and Lia Neal.
Kennedy is trying to make her first Olympic team. Manuel, Weitzel, Smoliga, Vollmer, Weir and Neal already are going to Rio.
Jessica Hardy, who won the 50 free at trials four years ago, wasn’t among the top 16 qualifiers.
Paralympic long jump champion Markus Rehm will not be seeking selection for the Rio de Janeiro Olympics, after all.
Rehm, a right leg amputee, was aiming to become the second athlete with a carbon-fiber prosthesis to compete at the Olympics and Paralympics after now-disgraced South African runner Oscar Pistorius in 2012.
The IAAF announced his decision after Rehm met on Friday with IAAF General Secretary Jean Gracia and agreed to join a working group on the use of prostheses in competition, with the aim of changing rules to allow athletes with prostheses to compete in future world championships.
To become eligible for the Olympics, Rehm had to prove that his prosthesis gives him no advantage over other athletes. A study he commissioned on the issue was inconclusive.
