• French youngster beats No 7 seed 6-3, 6-4 in Cincinnati

• Jessica Pegula battles past Swiatek to reach women’s final

In the middle of a tense, erratic start to a rain-delayed semi-final day in Cincinnati, Arthur Fils found himself locked in defence and miles behind the baseline on his serve at 3-3. He scurried from sideline to sideline, lunging toward the ball at full stretch, seemingly with no real chance of turning things around. As Flavio Cobolli swept to the net with the intention of finishing Fils off, however, the Italian soon learned that his opponent had another gear to reach. From far wide of the court, Fils pulverised a forehand passing shot winner beyond his astounded opponent, drawing a roar from the crowd.

That one point alone provided evidence of the athleticism, explosiveness and sheer audacity that have long marked Fils as such a rare, exciting talent, and it also set the tone for a monumental victory. From that moment onwards, Fils took control of the match and he marched into his first Masters 1000 final at the Cincinnati Open with a supreme performance, defeating Cobolli, the No 7 seed, 6-3, 6-4.

With one semi-final in her last seven tournaments, the coming months will define the next stage of her career

Towards the end of a messy first set tie-break late on Wednesday, Aryna Sabalenka wildly sprayed another painfully nervous backhand before slamming her racket to the ground. As the racket connected with the acrylic floor, its vibration dampener detached from the strings and rolled off in the direction of the broadcast camera pit by the side of the court.

With the diminutive 20-year‑old Czech player Sara Bejlek leading Sabalenka 6-5 in the tie-break, this slapstick sequence forced play to pause while the Belarusian and a couple of volunteers comically searched for the missing vibration damper underneath the cameras until she gave up and retrieved a new one. A few minutes later, Sabalenka trailed by a set.
