At the Monaco clay court tournament, Sinner not only competed in the men's singles but also partnered with a Belgian player born in 1999.
Jannik Sinner participated in both the singles and doubles events at the Monte Carlo Masters 2026, but decided to withdraw early from the doubles competition.
Sinner was initially paired with Zizou Bergs for the Round of 16 match against Guido Andreozzi and Manuel Guinard, scheduled to take place this afternoon (April 9) (Vietnam time), but the match could not be held after the pair confirmed their withdrawal.
According to European media, Koen Bergs, Zizou Bergs' father, said the decision came from Sinner, as the Italian player wanted to focus on bigger goals in singles.
He shared that this was an understandable choice, as Sinner still had a chance to compete for the world number one ranking at this tournament.
Previously, Sinner was the one who suggested the Belgian player partner with him, according to Bergs: "We were practicing at Indian Wells, having fun and chatting. Then he said, 'Hey, would you like to play doubles with me in Monte Carlo?'"
The day before the tournament, Sinner and Bergs also made an impressive debut, defeating the pair of Tomas Machac and Casper Ruud 2-0 (6-4, 7-5) in 83 minutes.
Despite playing together for the first time and not being professional doubles players, the two showed commendable chemistry. Statistically, the pair had 8 aces and successfully converted 4 out of 9 break point opportunities.
Sinner's withdrawal means Bergs no longer has a chance to advance deep in the doubles event.
However, both will focus all their efforts on the singles. Sinner is aiming for the championship and hopes to reclaim the world number one ranking if Carlos Alcaraz falters, while Bergs is preparing to face Alexander Zverev after his surprising victory over Andrey Rublev in the first round.
