World champion Sydney McLaughlin: I can only get faster from here

USA star Sydney McLaughlin believes she can still go faster after smashing her own world record to take 400m hurdles gold at the World Championships.

The 22-year-old broke the world record for the fourth time in 13 months with a stunning time of 50.68 seconds on Friday in Eugene.

It cut almost a second off her pervious mark of 51.41 seconds, which she made at Hayward Field last month.

Olympic champion McLaughlin said: "The time is absolutely amazing and the sport is getting faster and faster. I only get faster from here.

"I am super grateful. It all came together. It was absolutely unreal to have my family in the stands. So this was for me so big, after Tokyo, not having anybody, this was like a redemption.
