Wimbledon: Carlos Alcaraz battles to win, Novak Djokovic and Andy Murray drop a set before advancing; Danielle Collins biggest casualty of Day 1

Novak Djokovic became the first player to win 80 matches at all four Grand Slams as he made a successful start to his Wimbledon title defence on Monday while teenage star Carlos Alcaraz battled over five sets to make the second round. Six-time champion and top seed Djokovic saw off South Korea's Kwon Soo-woo 6-3, 3-6, 6-3, 6-4. But 20-time Grand Slam winner Djokovic was made to work after falling a break down in the opening two sets against his 81st-ranked opponent. "Now we have got to 80 wins, let's get to 100," said Djokovic. Djokovic, 35, is attempting to win a fourth successive Wimbledon title and join a select group. In the Open era, only Bjorn Borg, Pete Sampras and Roger Federer have managed such a streak at the All England Club.

Next up for Djokovic is Thanasi Kokkanikis. "Novak is kind of a brick wall," said the Australian. Alcaraz, a potential quarter-final opponent for Djokovic, came back from two sets to one down to defeat Germany's Jan-Lennard Struff. The 19-year-old fired 30 aces and 73 winners in a dazzling display of shot-making to win 4-6, 7-5, 4-6, 7-6 (7/3), 6-4. "Last year, I played five sets in the first round here as well so this shows how much I like grass," joked Alcaraz.

Spain's Alejandro Davidovich Fokina knocked out 2021 semi-finalist Hubert Hurkacz courtesy of the tournament's first final-set 10-point tiebreak. World number 37 Davidovich Fokina triumphed over the seventh-seeded Pole 7-6 (7/4), 6-4, 5-7, 2-6, 7-6 (10/8) in a match interrupted twice by rain. "When the rain came at 5-5 in the third set, I didn't know whether to have lunch or take a siesta," admitted 2017 junior champion Davidovich Fokina, who needed five match points to seal the win. Two-time Andy Murray also made it through,
