I think we played quite a good game and she was improving as the match was going on," said Pliskova, who was leading 6-2 3-4."I wish her only the best. It's not the way I want to win so hopefully she is going to be fine for Wimbledon."Related topicsTennisMore on this storyLive scores, results and order of playGet tennis news sent straight to your phonePublished2 days ago
