American fourth seed Sofia Kenin was knocked out of Wimbledon in the second round on Wednesday, losing in just 45 minutes to compatriot Madison Brengle.
Former Australian Open winner Kenin lost 6-2, 6-4 to 82nd-ranked Brengle.
However, second seed Aryna Sabalenka showed exceptional grit to rally from a set down to beat British wildcard Katie Boulter in a thrilling match to reach the third round of Wimbledon for the first time.
Sabalenka’s best result at the grasscourt Grand Slam was a second-round showing on debut in 2017 as a qualifier but she bettered that with a 4-6 6-3 6-3 victory in a match lasting over two hours.
