Lyles, Richardson show why they're the world's fastest


Americans Noah Lyles and Sha'Carri Richardson have cemented their status as the fastest sprinters in the world this year with victories at the Weltklasse Diamond League meeting.

But after Nina Kennedy's triumph at a special pole vault event on the eve of the famed Zurich meeting on Wednesday, fellow Australian Catriona Bisset couldn't quite repeat the dose 24 hours later as she finished runner-up in the 800 metres.

Richardson, who captured her first world 100m title in Budapest last week in a sizzling 10.65 seconds, pulled away from the field over the final 30m in Zurich to cross in 10.88 on Thursday.

Lyles, golden in the sprint treble of 100, 200 and 4x100 relay in Hungary, held off American teammate Erriyon Knighton to win the 200 in 19.80, an impressive time in the chilly conditions. Knighton clocked 19.87 in second.

Leading the Australian contingent, Newcastle-born Bisset chased home Laura Muir in the two-lap event, clocking 1min 58.77sec to the dominant Briton's 1:57.71.

Jamaica's Shericka Jackson maintained her dominance over 200m with an easy victory. Four days after her jaw-dropping 21.41 time in Budapest - the second fastest in history - she ran 21.82.

Kyron McMaster, of the British Virgin Islands, handed world record holder Karsten Warholm his first 400 hurdles loss this season, taking victory in 47.27 to edge the weary-looking world champion Norwegian who crossed in 47.30.

"The next time, it will be my time for revenge but we are all very good competitors," Warholm said.

"The level is so high, I cannot have bad days anymore. The world championship was the most important thing, but of course I want to win everything."

Armand Duplantis, of Sweden, sailed over 6.00m to win the pole vault, but failed in his three attempts at 6.23 which would have been the seventh time he's bettered the world record.

Duplantis' Australian pal Kurtis Marschall, bronze medal winner in Budapest, finished fifth this time with a 5.85m vault.

Olympic champion Mutaz Barshim of Qatar cleared 2.35 metres to win the high jump to earn a bit of redemption after his disappointing bronze in Budapest, while Australian Brandon Starc was last in the 10-man field with his 2.20 clearance.

American Yared Nuguse pipped the newly-crowned British world champion Josh Kerr at the line to win the men's 1500m in 3:30.49 by two hundredths of a second, while Australia's Stewie McSweyn came home seventh in 3:31.92.
