**Jannik Sinner’s Playful Jab at Brother Marc for Skipping Italian Open Final**
After losing the 2025 Italian Open final to Carlos Alcaraz 7-6(5), 6-1 on May 18, Jannik Sinner lightened the mood with a sarcastic dig at his brother Marc, revealing why he didn’t join their parents, Hanspeter and Siglinde, at the Foro Italico. In his runner-up speech, Sinner quipped, “A special thanks to my brother, who instead of being here went to Imola to watch Formula 1,” as reported by Sportskeeda and Express.co.uk. The playful jab, met with laughter from the Rome crowd, referenced Marc’s decision to attend the Emilia-Romagna Grand Prix, 80 miles away, over supporting Jannik courtside.[](https://www.sportskeeda.com/tennis/news-jannik-sinner-reveals-real-reason-brother-marc-join-parents-italian-open-final-playful-jab)[](https://www.express.co.uk/sport/tennis/2056921/jannik-sinner-rome-masters-carlos-alcaraz)
The comment, shared by @TheTennisLetter on X, highlighted the brothers’ close bond, with Marc, adopted from Russia at nine months old and now working in fashion in Monte Carlo, rarely attending Jannik’s matches, per EssentiallySports.com. Siglinde, known for leaving matches due to nerves, was present despite a brief semifinal exit, per motorcyclesports.net. Fans on X, like @ivabianconero, praised Sinner’s humor, with @StoolTennis calling it “iconic.” Reddit users noted the Grand Prix’s proximity likely made Marc’s trip a planned choice.[](https://www.essentiallysports.com/atp-tennis-news-jannik-sinner-hilarioulsy-trolls-brother-who-has-his-priorities-straight-as-he-refuses-to-show-up-at-italian-open-final/)[](https://www.reddit.com/r/tennis/comments/1kpq1dw/sinner_in_his_postmatch_interview_after_losing_to/)

His graciousness shone through, praising Alcaraz and wishing him luck for Roland Garros, per @DExpress_Sport. The jab at Marc, amplified by @tennismagazin, added a relatable touch to Sinner’s persona, endearing him to fans as he prepares for Paris with humor and resilience.
