SACRAMENTO • Rising star Christian Coleman's weekend of disappointment continued on Sunday as he lost in the 200m at the United States nationals and world championships trials to Ameer Webb.
Coleman, beaten by Olympic silver medallist Justin Gatlin in the 100m on Friday, was pipped by 0.01 of a second by Webb who closed quickly to win in 20.09 at Sacramento's Hornet Stadium.
"It's been a long weekend," said Coleman, 21, the year's fastest man at 9.82sec in the 100 metres. "I felt my legs tighten up near the end, but no excuses.
"It was a pretty successful week, qualifying for the team in two events."
Elijah Hall-Thompson was third in 20.21.
Co-favourite Noah Lyles' world championship hopes ended when he withdrew from the semi-finals with a hamstring strain.
Former world champion Tyson Gay will not be able to compete at August's world championships after he failed to reach the final of either of his preferred sprint events.
Gay missed the final of the 200m after finishing in 21.37 in his semi-final. The 34-year-old ended third in his 100m heat on Friday.
Despite the failure, Gay, who has struggled with form since the shooting death of his teenage daughter in Kentucky last October, said that he had no intention of ending his career just yet.
"I'm going to try to race at least a couple more times, hopefully," he said. "I'm still fit, I've just got to put it together."
Gay owns the second-fastest 100m - 9.69 behind Usain Bolt's world record of 9.58.
In Osaka, Japanese teenager Abdul Hakim Sani Brown said he is eyeing bigger scalps at the world championships in London after completing an impressive sprint double of national titles over the weekend.
The 18-year-old upset members of Japan's Rio Olympic silver medal-winning 4x100 metres relay team to win the 100m in a personal best 10.05 on Saturday, while on Sunday he ran a personal-best 20.32 to seal the 200m, two years after making the semi-finals at the world championships in Beijing.
No Japanese sprinter has ever broken the 10-second barrier in the 100m, with Koji Ito coming closest when he ran 10 seconds flat in 1998.
But former 100m and 200m junior world champion Sani Brown, born to a Ghanaian father and Japanese mother, is emerging as the man most likely.
"Even I'm surprised," said he of his weekend feats. "I didn't know I could run like this. I hope I get the chance to compete against top sprinters and break the 10-second barrier."
He became the first to complete the national sprint double since Shingo Suetsugu's 2003 sweep.
