Iga Swiatek keeps on winning

Iga Swiatek, who turned 21 on Tuesday, is on the longest unbeaten run in the women's tour since Serena Williams bagged 34 victories in succession in 2013.

The Polish player, gunning for a second title in three years at Roland Garros, appeared a tad shaky in the initial games before marching past the 11th seed to set up a meeting with Russian Daria Kasatkina for a place in Sunday's final.

The 2020 champion is bidding to become the fourth player since 2000 to lift the Suzanne Lenglen Cup multiple times after Justine Henin, Serena Williams and Maria Sharapova.

Djokovic still struggling mentally in battle to return to form

The 20-times Grand Slam champion was unable to defend his Australian Open title in January after being deported from the country, having initially been admitted to the tournament despite not taking the vaccine.

The 34-year-old also sat out ATP Masters 1000 events in Miami and Indian Wells.

"The challenge is definitely more on the mental and emotional side," Djokovic said as he prepares to begin his Madrid Open campaign on Wednesday (NZ time).

Djokovic into Dubai quarter-finals

Just as against Lorenzo Musetti in his opening match, Djokovic received plenty of vocal support from a large crowd at the Aviation Club and responded with some dazzling tennis under the lights.

Djokovic remains quiet on vaccination

The state of Victoria, where the Grand Slam event takes place in Melbourne, has introduced a vaccine mandate for professional athletes, although authorities have not yet clarified what the requirement will be for those coming from abroad.

"Things beings as they are, I still don't know if I will go to Melbourne, Djokovic said.

"I will not reveal my status whether I have been vaccinated or not, it is a private matter and an inappropriate inquiry.

Djokovic has won the season's opening Grand Slam a record nine times, including the last three editions.

Djokovic upset in Monte Carlo

The 30-year-old Evans emerged triumphant in the pair's first meeting to end the Serb's perfect 10-0 start in 2021.

Djokovic struggled to find any kind of rhythm on a windy day at the ATP Masters 1000 event and committed 45 unforced errors during the two sets, more than double of Evans.

"It hasn't sunk in yet," Evans said in his courtside interview. "I couldn't quite believe the last ball went over the net. It nearly didn't.
