16:03 CET - Taylor Fritz's ATP Finals campaign is up and running in fine fashion, putting in a supreme performance to claim a comfortable 6-3, 6-4 victory over Lorenzo Musetti.
Last year's runner-up, Fritz, looked in fantastic touch on the indoor courts, but in truth, Musetti clearly had very little energy left after a gruelling few weeks and playing in the Athens final just two days ago.
15:10 CET - Advantage, Taylor Fritz! A powerful set of tennis from the American has seen him overwhelm home favourite Lorenzo Musetti, capturing the opener 6-3. Has the Italian got a response?
13:50 CET - Defending champion Jannik Sinner faces Felix Auger-Aliassime later tonight, but meanwhile, we are just minutes away from the clash between last year's runner-up Taylor Fritz and Lorenzo Musetti!

11:00 CET - Hello and welcome to the final chapter of the 2025 season with the ATP Finals in Turin continuing this afternoon. The first match of the day sees Lorenzo Musetti (who takes Novak Djokovic's place) take on world number six Taylor Fritz from 14:00 CET.
After losing to Djokovic in the final at Athens at the weekend, Musetti will be hoping to prove that he deserves his spot in this showpiece event by getting the better of Fritz in this intriguing Finals opener.
What will encourage the Italian is that Fritz has had an underwhelming end to the season on the ATP tour, only making it past one round in Basel and the Paris Masters last month.
