Hannah Roberts watched China’s Deng Yawen put together a brilliant run in the freestyle BMX competition at the Paris Olympics, and in the ultimate game of one-upmanship, the five-time world champion from the United States knew she had to go bigger.

She went plenty big. She just couldn’t finish.

Roberts wound up crashing on a front flip late in her first run Wednesday, and was only seconds into her second when she put her foot down on the landing. That left the heavy favorite out of the medals entirely, and left Deng on the top step of the podium along with silver medalist Perris Benegas of the U.S. and bronze medalist Natalya Diehm of Australia.

Benegas put together a solid first run of 83.40 points with some big air and bar spins, only to go even higher with a 360 into an X-up that carried her to the second step of the Olympic podium.

“It’s just the best run that counts, so there’s everything to win, nothing to lose,” Benegas said. “I just told myself, ‘Let’s go.’”

Deng finished with a score of 92.60 points at the urban sports park built at Place de La Concorde. Benegas rose to the occasion after a fourth-place finish at the Tokyo Games to score 90.70. Diehm was a surprising third with 88.80.

The medal for Deng came after the Chinese team failed to qualify anyone for Tokyo. The result, coupled with the fact that China qualified three and had to leave one rider at home because of quota numbers, showed how far the nation has come.

The medal round got off to an inauspicious start for Roberts, who was going over a jump during a warmup session when she collided with Czech rider Iveta Miculycova. The American seemed to grab at her right shoulder as she ran immediately off the course, leaving her yellow bike gleaming in the sun on the purple-hued flats.

Roberts was on her way to a medal-worthy run before trying the front flip, which went awry right from the start.

“No thought of holding back in my first run. I did the front flip in practice perfectly and when it came time to do it in the contest, I slipped my foot off the pedal before I even snapped,” she said, “and by that point it was too late.”

In men’s BMX freestyle, Jose Torres Gil of Argentina won the men’s freestyle BMX gold medal, putting together a sublime first run that withstood the best efforts of British world champion Kieran Reilly and French superstar Anthony JeanJean. Marcus Christopher of the U.S. placed fourth.

Jha makes history; No. 1 stunned

Kanak Jha secured the U.S. its best Olympic run in men’s table tennis by reaching the last 16, while the shock of the tournament came when world No. 1 Wang Chuqin of China lost to 26th-ranked Truls Moregard of Sweden.

Jha, the 120th-ranked player in the world, beat Panagiotis Gionis of Greece 4-2 to top Jimmy Butler’s round-of-32 appearance at the 1992 Barcelona Olympics.

The 24-year-old Jha, who prepared for the Games with help from GoFundMe, said he was “feeling relieved.”

Jha will now face Tokyo 2020 silver medalist Fan Zhendong.

The major upset came when Wang lost 4-2 to Moregard in their round-of-32 match. Wang had won the gold in mixed doubles Tuesday.
