A stunner at the Rio Olympics: Michael Phelps has been beaten.
Joseph Schooling of Singapore built a big lead on the opening lap and easily held off the hard-charging Phelps to win gold in the 100-meter butterfly. So, unless Phelps decides to come out of retirement again, his final individual race at the Olympics will go down as a silver. He still has a chance to win his 23rd gold medal in his final race of the Olympics, the 4x100 medley relay.
Phelps was sixth at the turn and Schooling - almost exactly a decade younger than the 31-year-old American - wouldn't let him pull off one of his patented comebacks on the return lap. The winning time was 50.39 seconds.
Phelps shared the silver with two other longtime rivals, Chad le Clos of South Africa and Laszlo Cseh of Hungary. They all touched in 51.14.

MEDAL ALERT-WORLD RECORD: Iran opened its account in Rio with a gold medal and a world record as Kianoush Rostami outmuscled his rivals to win the men's 85-kilogram weightlifting class.
Rostami knelt and kissed the platform before adopting a position of prayer after his lift of 217 kilograms in the clean and jerk, which when added to his 179 from the snatch gave him a winning total of 396 - one kilo above the world record he had set in May.
The silver went to China's Tian Tao on 395. Tian had a high-risk strategy of attempting 217 on his last lift after twice failing at 210, thus risking finishing last if he didn't make the lift.
Bronze went to Romania's Gabriel Sincraian on 390. Sincraian only returned last year from a two-year ban for doping.

Tirunesh Dibaba already clinched a track and field bronze in the 10,000 meters early Friday. Now it is time for younger sister Genzebe to step forward in the 1,500.
World champion Genzebe easily qualified for the semifinals of the 1,500 late Friday, distancing opposition with a kick a lap from home and coasting from then on.
But she was so relaxed that she swerved closely to the inside rail and had to take a corrective step to get back in line. It was her only problem toward a time of 4 minutes 10.61 seconds, more than 20 seconds off her world record.
The semifinal is Sunday and the final on Tuesday.
