EASTBOURNE: New world number one Ashleigh Barty has suffered a pre-Wimbledon injury scare, withdrawn from this week’s Eastbourne grasscourt tournament with a recurrence of a right arm injury. The 23-year-old became the first Australian woman to reach the top of the WTA rankings for 43 years on Sunday when she won the Birmingham Classic and will be top seed at Wimbledon. “It’s an injury I’ve had to manage since I was 16 years old,” Barty told reporters at Devonshire Park on Monday. “It happens when I have a spike in load, it’s just a bone stress injury and I need to look after it.” Her coach Craig Tyzzer said Wimbledon might not have been “a viable option” had she played too much this week. Barty won the French Open earlier this month, the first Australian woman to do so in 46 years, and is on a 12-match winning streak heading to the All England Club. She is optimistic she will be ready in time.
