Mirjana Lucic-Baroni upset world No. 3 Simona Halep in the second round of Roland Garros, a week after a monumental collapse in Strasbourg. The 33-year-old led Madison Keys by a set and 5-0 but lost the match, 4-6, 7-6 (3) 7-6 (0).

“I would like that nobody saw the result, that nobody knows about it, but it's obviously tough,” she said. “I was playing amazing tennis last week, and so is Madison. She's playing best tennis of her career and very confident. I was playing great, and at 5-0 she let her hand go and started hitting some winners. I had one bad service game and then I got a little bit tight.

“Nobody likes to admit, but [choking] happens. Still I was happy because we played a really competitive third set, as well. So that shows mental toughness on my part that I'm really happy with, that I have been working on.

“Even though I lost, I had a couple of glasses of wine that night.”
