World number one Jannik Sinner survived an all-Italian Centre Court dogfight against Matteo Berrettini to book his place in the third round of Wimbledon on Wednesday.
Sinner edged the opening two sets on tiebreaks under the closed roof but was rocked on his heels by a Berrettini fightback before prevailing 7-6(3) 7-6(4) 2-6 7-6(4).
Berrettini, who was runner-up to Novak Djokovic in 2021 but was plagued by injuries last year and is now ranked down at 59th, looked capable of dragging the match into a decider with some heavy-metal tennis.
Top seed Sinner was wobbling when some scrappy groundstroke errors meant he went a break down early in the fourth set, but he managed to wrestle back control in the nick of time.
Berrettini saved a match point when serving at 5-6 in the fourth set and belted away a forehand to set up the third tiebreak of an absorbing tussle.
The law of averages suggested the big-serving Berrettini would come out on top this time but once again Sinner was as cool as a cucumber when it mattered to get the job done shortly before Wimbledon's 11pm curfew.
Earlier in the day, Casper Ruud, the three-times Grand Slam runner-up fell 6-4 7-5 6-7(1) 6-3 to Italian Fabio Fognini.
"I'm disappointed that I lost but I know my abilities on this surface and I'm trying to be realistic," said Ruud, whose best results have come on claycourts and hardcourts.
"I just find it difficult. I find it fun as a challenge and I try my best every year. I haven't given up on it yet but it's really difficult for me somehow, the movement and feeling confident out there."
Fognini's fellow Italian and French Open runner-up Jasmine Paolini came through a tight first set to down Greet Minnen 7-6(5) 6-2.
