Sloane Stephens suffers Wimbledon shock but Caroline Wozniacki and Venus Williams progress

US Open champion Sloane Stephens became a big-name casualty on day one of Wimbledon.

The fourth-seed, who reached the final of the French Open last month, looked badly out-of-sorts as she fell 6-1 6-3 to world number 55 Donna Vekic.

“I always try to be aggressive,” she told the BBC.

“I struggled with my serve in the wind but hopefully I can improve.

“I played all the tournaments on grass coming here and that has helped me.”

2017 semi-finalist Magdalena Rybarikova was also on the receiving end of a shock, losing in straight sets to Sorana Cirstea.

However, there were much more routine opening round matches for Caroline Wozniacki and Venus Williams.

Australian Open finalist Wozniacki needed just 59 minutes to overcome Vavrara Lepchenko 6-0 6-3.

Williams, meanwhile, who lost last year’s final to Garbine Muguruza, eased into the second round despite losing the opening set against Sweden’s Johanna Larsson.
