SA's Lloyd Harris is now ranked above Roger Federer in ATP rankings

South African tennis ace Lloyd Harris has moved past legendary Swiss Roger Federer in the latest ATP Tour rankings.

This comes after Harris, 25, reached the last 16 of a Masters 1000 event for the first time at the Miami Open last week.

It saw the Capetonian move up four spots in the rankings to No 40, leaving him four spots above Federer, who dropped 18 spots to 44th on Monday.

This is Federer's lowest ranking since 12 June 2000 when he was 18 years old and yet to win an ATP Tour title (he now boasts 103).

Federer, the winner of 20 Grand Slam titles, hasn't played since last year’s Wimbledon because of a knee injury and it's still uncertain when he'll return to the tour.

Federer turns 41 in August but hasn't yet hinted at retirement.

Harris, meanwhile, will hope his Miami run - which was ended by Poland's Hubert Hurkacz - will set him up for the remainder of the season.

It had been an inconsistent year for Harris - he entered the Miami Open with a 2-7 ATP win-loss record - but he seems to be finding the form that saw him progress to the quarter-finals of the US Open last year.

Harris famously beat Spain's Rafael Nadal in Washington DC last year and reached a career-high ranking of No 31 last September.
