Key scenarios

Seeded Swiatek moves to SW19: Swiatek was junior champion at Wimbledon only four years ago. Now, having won his last six tournaments, including his second major title at Roland Garros, Swiatek is looking to extend his 35-game winning streak. A title run would extend Swiatek’s streak to 42 matches, which would be the ninth-longest winning streak in WTA history. Although she admits she is still learning how to effectively deploy her devastating grass game, Swiatek posted her career-best result at Wimbledon last year in the round of 16.

Serena Williams returns: The last time Serena was on a singles court, she was forced to retire in the first round of Wimbledon last summer. Following her return to doubles competition at Eastbourne, the 23-time major champion is set to make her singles return at Wimbledon.

Jabeur puts Paris behind her: Jabeur entered Roland Garros in scintillating form only to be upset in the first round. So far, the Tunisian hasn’t let the disappointment linger. She nailed her top seed in Berlin to claim her second title of the year and will go to Wimbledon as world No. 2. Jabeur posted his best result at Wimbledon last year in a run to his second major quarter-final.

Gauff ready for a big step on the grass: After playing in her first grand final at Roland Garros, the 18-year-old American is now looking to Wimbledon, where she has never lost before the round of 16. So far, she has shown no signs of post-Paris disappointment. Gauff played her first semi-final on grass in Berlin.

Raducanu returns home: The defending US Open champion put her name on the map at Wimbledon last summer, making the Round of 16 a wild card. Needless to say, a lot has happened since. The 19-year-old was unable to play a grass court event this summer due to injury. Wimbledon will therefore be his only home tournament.

Veterans wanting to have their say: Former champions Angelique Kerber, Simona Halep and Petra Kvitova all had a solid winning streak in the week leading up to Wimbledon.

Beatriz Haddad Maia wins the dark horse title: The 26-year-old Brazilian has won Nottingham and Birmingham and is in the Eastbourne quarter-finals. It’s 12-0 on grass, a run that earned him a top seed at Wimbledon. The last Brazilian woman to win Wimbledon was Maria Bueno, who won the event three times in 1959, 1960 and 1964.
