Britain's Heather Watson matched her best Wimbledon run with a stunning second-round win over Latvia's 18th seed Anastasija Sevastova.
Watson, 25, won 6-0 6-4 in just over an hour to reach the third round for the third time in her career.
The Guernsey player raced to the first set in 19 minutes, then fought back from two breaks down in the second.
She will play either former world number one Victoria Azarenka or 15th seed Elena Vesnina in the last 32.
The former British number one has dropped outside the world's top 100 after reaching a high of 38 in January 2015.
