Johanna Konta put a difficult week behind her to reach the second round of the Porsche Grand Prix in Stuttgart with victory over Japan's Naomi Osaka.
Konta, who left the court in tears after being verbally abused by Romania captain Ilie Nastase in a Fed Cup tie last week, won 7-6 (7-5) 3-6 6-1.
The British number one found it tough but Osaka's challenge faded in set three as she struggled with an injury.
Konta will face Latvia's Anastasija Sevastova in round two.
The 25-year-old told BT Sport: "I think obviously you could tell she [Osaka] was struggling, I hope everything is OK with her and she recovers quickly.
