He's run as fast as any Australian man on home soil, but Rohan Browning isn't satisfied.
The 21-year-old, who booked a world championship berth with his 10.08-second 100m in Brisbane on Saturday night, wants to do it again and again.
The bubbly Sydney talent made the most of a tailwind to finish second in a photo finish to Japan's first sub-10 second runner, Yoshihide Kiryu, at the Queensland Track Classic.
He's now the equal-third fastest Australian behind Patrick Johnson and Matt Shirvington, while only Josh Ross - in Brisbane 12 years ago - has matched that time in Australia.
"It's one thing to run fast once, but it doesn't mean anything unless you can back it up," a pumped Browning told AAP on Sunday.
"Those guys in contention are doing that all the time."
The time - a personal best by .11 seconds - puts Browning in pole position at next month's nationals in a deep field that should include 20-year-old Jack Hale, Jake Doran (18) and Trae Williams (21).
Hale ran 10.19 to take third and better his best for the second time in two weeks, while teenager Doran (10.15) and Williams (10.10) boast impressive, recent personal bests.
"It'll be different being in the hot seat," Browning, who missed the Commonwealth Games 100m final by less than one hundredth of a second, said.
Riding an emotional high on Saturday, Browning opted to skip the 200m but hoped to contest the sprint double at nationals.
He won the Perth Track Classic 200m in 20.77 and aimed to go under the world championships qualifying mark of 20.40 by the July cut-off.
Qualifying the 100m relay team for the worlds is the other big goal, with the young, confident squad a chance at Yokohama's World Relays in May.
