Top seed Simona Halep has claimed her performance was unprofessional as she was knocked out of Wimbledon on Saturday in an epic three-set clash with Hsieh Su-wei.

Halep was the heavy favourite going into the match and she looked to be in control when she stormed into a one set lead at SW19.

She broke her opponent’s serve on seven occasions but the Taiwanese world number 48 never gave in and won 3-6 6-4 7-5.

Romanian Halep did look tired at occasions on Saturday afternoon but she admits she should have done more to finish the match off.

Hsieh is now through to the last 16 of the singles for the first time but Halep admits she only has herself to blame.

She told BBC Sport: “I was leading the match, I was up, and I couldn’t finish it. I’m not hard. I’m just realistic and honest with myself. I accept that it was an unprofessional attitude from me today.

“I just was too negative to myself, talking too much. I think because I was tired, because I’m tired, I couldn’t stay focused for every ball.”

In the men’s draw, British number one Kyle Edmund was knocked out by three-time champion Novak Djokovic.

The Serbian fought back valiantly to win 4-6 6-3 6-2 6-4 on Centre Court, while Spaniard Rafael Nadal also tasted victory as he beat Alex de Minaur.

Roger Federer remains the 1.75 favourite, with Djokovic and Nadal both priced at 6.00.
