• Ukrainian beats French Open champion 7-6 (3), 6-1

• Gauff’s loss provides biggest upset of tournament so far

“Yeah, this definitely sucks,” said a tearful Coco Gauff. She was trying, and struggling, to put her finger on why she had become the most high profile casualty of a typically consequential first round at Wimbledon. “I don’t know, I just feel a little bit disappointed in how I showed up today.”

The question before the tournament was whether Gauff could cement her standing at the top of the game by adding Wimbledon to this year’s French Open title for a “Channel Slam”. The answer turned out to be a rather decisive “no”. The second seed was knocked out in less than two hours on Tuesday evening, with the biggest shock how easily she was dispatched by the Ukrainian Dayana Yastremska.

• Reigning champion fights back to beat Eala 3-6, 6-2, 6-1

• Injury-plagued title holder displays tough mentality

Barbora Krejcikova avoided the curse of the early Czech-out on Tuesday as she held off the hustle of the rising Filipino star Alexandra Eala to progress to the second round at Wimbledon.

The defending women’s champion has seen her season blitzed by injury, and was predicted by Wimbledon’s in-house supercomputers to lose here and echo her compatriot Marketa Vondruosava, who last year became the first women’s champion to exit at the first round since 1994.
