Sarah Lavin finishes fifth in semi-final

Sarah Lavin finished fifth in her 100m hurdles heat in an incredibly fast semi-final at the World Championships in Oregon.

Running in the third heat, the Limerick athlete ran a fine time of 12.87, just outside her personal best of 12.84. Jamaican Britany Anderson clocked a new national record with a time of 12.31 while Jasmine Camocho-Quinn posted a season best 12.32.

Heat one produced even better as Nigeria's Tobi Amusan set a new world record of 12.12 with that heat also producing two personal bests, three season bests and two national records.

Amusun would go on to run 12.06 to take gold in the final, but that time was aided by an illegal tailwind.

A new world record was also set in the pole vault as Sweden's Armand Duplantis broke his own pole record with a jump of 6.21 metres on the way to winning his first gold medal at the World Championships.

The Olympic champion cleared 6.00m to make sure of the title, before he set his sights on his own record of 6.20m set at the World Indoor Championships in Belgrade earlier this year and improved upon it by 1cm with his second attempt.

The world title completes the 22-year-old's collection, making him the first pole vaulter to have won gold at the Olympics, World Championships, World Indoor Championships, World Junior Championships, World Youth Championships and European Championships.

Duplantis took two attempts at 5.87m before clearing 6.00m and 6.06m with ease to edge Dmitri Markov's Championships mark of 6.05m set in Edmonton in 2001.

He then had the bar raised to 6.21m, falling short on his first attempt but soaring to the world record on the second.

It was the third time this year that Duplantis has set a world record and his fifth record-setting jump overall after breaking
