Rafael Nadal preparing for a potential return to the tour

22-time Major champion Rafael Nadal's plans for the rest of the year seem up in the air. Recovering from an injury, along with the impending birth of his first child, has kept him occupied. However, the Spaniard might now be gearing up for his return to the tour as he shared an Instagram update in which he was seen practicing.

"Hola, Semana de entrenamientos y trabajo (Hello, week of training and work)" - Nadal on Instagram

It appears that Nadal is feeling healthy enough to be consistently training. He's on the entry list for the Paris Masters and has qualified for the ATP Finals, and they're likely to be the only tournaments he participates in if he makes a comeback.

Anett Kontaveit and Jelena Ostapenko pull out of San Diego Open

World No. 3 Anett Kontaveit has withdrawn from the San Diego Open due to a back injury. She had to retire from the ongoing Ostrava Open due to the very same reason, ending her title defense in the second round.

Jelena Ostapenko too won't be making the trip to San Diego. She picked up a foot injury during the Korea Open and seems to have made it worse by competing in Ostrava.

Nevertheless, most of the top 20 players will be participating in the San Diego Open, making it one of the most competitive fields of the season.

Novak Djokovic continued his good run of form to defeat Karen Khachanov 6-4, 6-4 in the quarterfinals of the Astana Open. It was his seventh consecutive win, that too without dropping a set. Meanwhile, Daniil Medvedev crushed Roberto Bautista Agut 6-1, 6-1 in their quarterfinal bout.

Djokovic and Medvedev are now set to face off in the semifinals. This will be their first meeting this year. The Serb leads 6-4 in the head-to-head and won their previous encounter at last year's Paris Masters.

Nick Kyrgios out of Japan Open due to injury

Nick Kyrgios seemed to be in good form at the Japan Open, where he reached the quarterfinals and semifinals in singles and doubles respectively. However, he has now withdrawn from the tournament due to a knee injury. The injury has been bothering him for some time now and it appears to be a little worse.

Fritz, who was to meet Kyrgios in the quarterfinals, moved on to the semifinals. The Australian will next be seen at the Swiss Indoors Basel.
