Ukrainian wildcard Elina Svitolina beat Belgian 28th seed Elise Mertens to reach the third round at Wimbledon on day four.
In a court two match of contrasting sets, the 28-year-old won 6-1 1-6 6-1.
Svitolina dominated the opener before appearing to struggle with something in her eye in the second, but she regained form to take victory.
On court 12, French Open runner-up Karolina Muchova suffered a shock first-round exit to Jule Niemeier.
The Czech 16th seed sustained a leg injury after falling over in the deciding set and went down 6-4 5-7 6-1 to German Niemeier, who reached the quarter-finals at Wimbledon last year but is ranked 87 places below Muchova.
