Jannik Sinner has split with his longtime coach Riccardo Piatti. The move is surprising because Piatti is like  a father figure to Sinner and has guided his career from a young age.

At the Australian Open earlier this year, Jannik Sinner hinted at adding new members to his team. This move rattled their relationship and led to the split. Though he reached the quarterfinals at the Australian Open, results have been underwhelming by his standards.

Sinner started working with Riccardo Piatti at age 13. By age 17, Sinner started winning ATP Challenger titles. He broke into the Top 100 world ranking in 2019. That year, he became the first teen to win an ATP 500 tournament since that category was created in 2009.

Piatti has coached several top players including with Ivan Ljubičić, Richard Gasquet, Borna Coric, Maria Sharapova, and Novak Djokovic.

Serena Williams is featured in a Super Bowl ad for the Tonal, a company that makes home gyms. The ad encourages women to use strength training equipment just like men.

Serena Williams was an early investor in Tonal. The ad shows Serena Williams working out using Tonal equipment.  In the ad, she says:

Never be afraid of your strength, because your body is capable of amazing things. The one they said you shouldn’t have. The one driven by a power they can’t see.  Own your strength, and see how far it takes you

Tonal’s products are mostly used by men. The company plans to use athletes such as soccer Lindsey Horan and swimmer Simone Manuel in the coming months as part of its “Strength Made Me” campaign which encourages women to be strong physically and mentally.
