Angelique Kerber knocked out of Porsche Tennis Grand Prix by Emma Raducanu

Fresh from helping Great Britain reach the finals of the Billie Jean Cup at the weekend, Raducanu continued her promising form on clay by breezing past the home favourite.

Both Raducanu and Kerber were playing as wild cards in Stuttgart, with the Briton tumbling down the rankings after time out to undergo three surgeries.

Meanwhile, former world number one Kerber only recently returned from 18 months out on maternity leave.

Raducanu got off to a flying start by breaking Kerber in the opening game and despite an immediate response from the German, the 2021 US Open champion took control and claimed the first set in 41 minutes.

Kerber was broken again at the start of the second set and although she managed to haul back level, Raducanu stepped up a gear and shrugged off a brief visit from the trainer to wrap up an emphatic win.

"It was very difficult to play Angie because she has so much history behind her," Raducanu said on BBC Sport. "You are not just playing Angelique Kerber, you are playing the person who has achieved all those amazing results.

"It wasn't the prettiest but I just focused on the next point and did not get too bogged down. So I'm happy to have got through that."

Also in Stuttgart, reigning US Open champion Coco Gauff rallied from 4-2 down in the deciding set to overcome fellow American and world number 134 Sachia Vickery 6-3 4-6 7-5.

And Tunisia's Ons Jabeur finally snapped a five-game losing streak to beat Ekaterina Alexandrova 2-6 6-3 7-6 (1), telling reporters: "I thought about withdrawing so many times because I couldn't take another loss."

In Rouen, Naomi Osaka's return to clay was cut short by a 6-4 6-2 first round defeat to Martina Trevisan.

Like Kerber, Osaka only recently returned to the tour following maternity leave, and was competing as a wild card.

In the Oeiras Ladies Open in Portugal, Britain's fifth-seeded Harriet Dart suffered a 6-3 6-1 defeat to home player Matilde Jorge.
