ALBUQUERQUE, New Mexico — Christian Coleman made sure the world record was his this time.

After being denied ratification last month for the fastest ever 60 meters when he clocked 6.37 seconds in a race that did not use electronic starting blocks, the world outdoor silver medalist ran even faster on Sunday.

Turning on the afterburners following his trademark fast start, Coleman breezed home in 6.34 seconds at the US Indoor Track and Field Championships in Albuquerque, New Mexico.

The time wiped out Maurice Greene's 20-year-old record of 6.39 seconds, a mark almost matched by runner-up Ronnie Baker, who crossed the line in 6.40 seconds.

"It feels like a blur," the 21-year-old Coleman told reporters when asked to describe what it felt like to run that fast. "My start was decent. When I transitioned, I stood up, and I felt as good as I've ever felt. I just kept running to the tape. For it to be the world record was pretty special."

The fastest man in the world last year time-wise, he took silver in the 100m at last year's World Championships in London, finishing ahead of world record holder Usain Bolt.

Coleman will lead a talented American team to next month's World Indoor Championships with the top-two finishers in each event in New Mexico securing berths for Birmingham, England.

"I just love racing in the big races, when everybody's watching," Coleman said. "I just flourish in those moments. It's not really in my personality, but when the lights are on, it just comes out."

Along with his world record, five other season-best performances were established in the rarefied air of Albuquerque, which aids sprinters but slows distance runners.

Chief among them was Sharika Nelvis's US record 60m hurdles time of 7.70 seconds as she defeated world outdoor record holder Kendra Harrison by two-hundredths of a second.

Olympic and world long jump Brittney Reese gave the Americans another big hope for gold in Birmingham, twice leaping 6.68m, the best mark in the world this year.

Up-and-coming Katie Nageotte added another season-best in the pole vault, soaring 4.91m to defeat world silver medalist Sandi Morris (4.86m). Nageotte then made three unsuccessful attempts at a world record 5.04m.

The women's 60m and 400m also produced the leading times of 2018. Courtney Okolo (51.16) edged out Shakima Wimbley by one hundredth of a second in the 400m and Javianne Oliver won the 60m in 7.02 seconds.

Shelby Houlihan and Paul Chelimo added their second titles of the meeting, winning the 1,500m in 4:13.07 and 3:42.91 respectively. World indoor high jump champion Vashti Cunningham also qualified for the team, with the daughter of former NFL quarterback Randall Cunningham clearing 1.97m.

Teen lands sprint double at Australia's trials

Teenager Riley Day won the sprint double at the Australian Athletics Championships on Sunday to clinch automatic selection in the 200 meters event at the Commonwealth Games.

Day, 17, carved out a personal best time of 22.93sec to win the 200m event on the last day of the selection trials for the April 4-15 Gold Coast Games.

The youngster is expected to race in the 200m and 4x100m relay at the Commonwealth Games but may need to be a discretionary selection for the 100m because she does not have a qualifying time after winning in 11.56sec.

"It's the icing on the cake — national champion, A-qualifier, a PB (personal best). I couldn't ask for anything more," Day told reporters. "My PB was 23.26 (for the 200m), so it's a fairly big drop for a sprinter.

"It's definitely a big competition (the Games) but I have to keep reminding myself I am only 17. I have hopefully a long way to way towards my best."

Alex Hartmann grabbed automatic selection for the 200m at the Commonwealth Games after claiming a fourth national title in the event.

The win leaves him only one behind the late Peter Norman's record in the event nationally, and his time in the final of 20.57sec landed a Games B-qualification.

Hartmann, 24, has a 20.45sec personal best as he eyes Norman's 1968 national record of 20.06. — Agencies
