Kerber cruises into semi-finals

Angelique Kerber eased into the semi-finals of the US Open following her straight set win over Roberta Vinci on Tuesday.

The second seed battled through a tough opening set but would eventually ease to a 7-5, 6-0 win on the hard courts in Flushing Meadows.

After the duo swapped service breaks twice early on to tie matters up at three games all, the match looked like it could go the distance.

Kerber seemed to be struggling for rhythm on serve and another break would see Vinci – a finalist in New York last year – serving for the set.

But the German rallied to save the break and would go on to win the final two games to seal an mistake-riddled set, where she made no less than 22 unforced errors.

That seemed to shake up the world number two, as she turned on the class in the second set.

Just 23 minutes and 14 winners later, Kerber had booked her place in the final four for the first time since 2011.

She awaits the winner of the other quarter-final, which features Anastasija Sevastova and Caroline Wozniacki. Either way, Kerber will face an unseeded player in the semi-final.

The win also keeps Kerber hopes of usurping Serena Williams from the top of the world rankings.
