An ice time for Sabalenka, but Alcaraz feels the heat

Mercury soars

During the match Alcaraz rushed to help a spectator who had collapsed in the stands, handing over a bottle of water as medics came to the woman's aid.

With players and fans searching for shade from the London heatwave, former England captain David Beckham watched the action from the royal box, alongside England manager Gareth Southgate, both of whom recently received knighthoods.

Wimbledon has a heat rule to safeguard the health of the players.

It allows a 10-minute break to be taken between the second and third sets for women's matches and between the third and fourth sets for men's matches, when the heat stress index is at or above 30.1 C.

Top women's seed Sabalenka used ice packs to beat the heat during her 6-1, 7-5 victory over Canadian qualifier Carson Branstine on Court One.

The 27-year-old Belarusian is a three-time Grand Slam champion, but suffered agonizing three-set defeats in this year's Australian Open and French Open finals.

The world No 1 has never been beyond the Wimbledon semifinals and missed last year's tournament with a shoulder injury.

"I felt really great. Super grateful to be healthy, ready to compete and to be through the first round," said Sabalenka, who next faces Czech world No 48 Marie Bouzkova.

Two-time Wimbledon finalist Ons Jabeur broke down in tears before retiring from her first-round match against Viktoriya Tomova for an unspecified reason. Tunisian Jabeur was trailing 7-6 (5), 2-0 when she brought a premature end to her clash with the Bulgarian world No 111.

Former US Open champion Daniil Medvedev, a Wimbledon semifinalist for the past two years, suffered a meltdown against France's Benjamin Bonzi.

Bonzi won 7-6 (2), 3-6, 7-6 (3), 6-2 in three hours and seven minutes, with the fuming Russian smashing his racket against his chair at the end of the match.

Elsewhere, Danish eighth seed Holger Rune threw away a two-set lead to lose to Chilean world No 143 Nicolas Jarry, while former finalist Matteo Berrettini crashed out and Stefanos Tsitsipas retired with an injury.

Former French Open winner Jelena Ostapenko was beaten 7-5, 2-6,6-2 by Britain's Sonay Kartal.

Australian Open champion Madison Keys came from a set down to beat Elena-Gabriela Ruse 6-7 (4), 7-5,7-5, but ninth seed Paula Badosa lost in three sets to Britain's Katie Boulter.

Former US Open champion Emma Raducanu defeated fellow Briton Mimi Xu 6-3, 6-3 to book a second-round date with 2023 Wimbledon winner Marketa Vondrousova.

The matches between third seed Alexander Zverev and Arthur Rinderknech and fifth seed Taylor Fritz and Giovanni Mpetshi Perricard were suspended due to Wimbledon's 11pm curfew. It also affected women's fifth seed Zheng Qinwen, who was scheduled to play Katerina Siniakova of the Czech Republic in a late night match.
