Jannik Sinner has hired former Italian player Simone Vagnozzi as his new coach. He recently split with his longtime coach Riccardo Piatti. Simone Vagnozzi  retired from professional tennis in 2015. He reached a career-high singles ranking of 161 and a doubles ranking of 74.

Speaking of his former coach Piatti, Sinner said

I will always look back the time we shared fondly,” said the 20-year-old Italian, who last appeared at the Australian Open. “I would like to thank Riccardo [and Piatti academy team members] Dalibor, Claudio, Andrea, Cristian and Gaia for everything they have done for me since the beginning of my career until today

Riccardo especially, he taught me many things that will forever remain a part of my tennis.

Sinner is shaking up his team to improve his game and win grand slams. Though Sinner has reached the quarterfinals of a grand slam twice, he has struggled to advance further.

Naomi Osaka got a wildcard to compete at Indian Wells. Her rankings have dropped out of the Top 75 after a year of dismal results. She won the tournament in 2018.

Since winning the Indian Wells title in 2018, Naomi Osaka won four grand slam titles – two Australian Open titles and two US Open titles. But since winning the 2021 Australian Open, her best grand slam result has been reaching the third round.

Naomi Osaka also took a break from the sport in 2021 for mental health reasons. She  missed Wimbledon and missed many tournaments.

Tennis can be a brutal sport. If players don’t have good results in the past 12 months, they can’t qualify for major tournaments. Either they need to go through the qualifying rounds or need a wild card from the tournament.
