The 24-year-old Italian is one of the most brutal offensive maestros on tour. A four-time Grand Slam champion, Sinner added Wimbledon glory to his reign as the then best tennis player in the world, making it his 4th final in a row. He defeated Spanish prodigy Carlos Alcaraz in a blockbuster final that lasted four sets. Although Sinner lost to him in the US Open final, the 2025 campaign was full of highs for the Italian.<\/p><p>Behind every successful <a href=\"https:\/\/theplayoffs.news\/en\/tennis\/\" class=\"trk-cta-link\" data-cta-trk='{\"ctaType\":\"Link\",\"ctaSubType\":\"main\"}'>tennis<\/a> player, is a supportive family that has sacrificed a lot. There is a lot that goes on behind the scenes that fans are occasionally unaware of. Over the years, Sinner has repeatedly stressed on the importance of his team and family. Born in South Tyrol, he started playing tennis at the age of 7 since his father liked the sport. But did you know that Jannik Sinner also has a brother?

He is currently working as a trainer for the fire brigade in South Tyrol, near Austria. He reportedly said in a 2023 interview, <em>&ldquo;The relationship with Jannik is normal, like that of most brothers. We played tennis &ndash; we tried at least. For a few years, I managed to keep up with him. Then he took off and it was impossible to exchange shots.&rdquo;<\/em><\/p><figure class=\"wp-block-embed is-type-rich is-provider-twitter wp-block-embed-twitter\"><div class=\"wp-block-embed__wrapper\">\n<blockquote class=\"twitter-tweet\" data-width=\"500\" data-dnt=\"true\"><p lang=\"en\" dir=\"ltr\">Jannik Sinner after losing to Carlos Alcaraz in Rome final:<br><br>&ldquo;Special thank you  to my brother who rather than being here is in Imola watching Formula 1.&rdquo; &#128514;&#128514;&#128514;&#128514; <a href=\"https:\/\/t.co\/8nPvHGZ7Vd\" class=\"trk-cta-link\" data-cta-trk='{\"ctaType\":\"Link\",\"ctaSubType\":\"main\"}'>pic.twitter.com\/8nPvHGZ7Vd<\/a><\/p>&mdash; The Tennis Letter (@TheTennisLetter) <a href=\"https:\/\/twitter.com\/TheTennisLetter\/status\/1924158024886992958?ref_src=twsrc%5Etfw\" class=\"trk-cta-link\" data-cta-trk='{\"ctaType\":\"Link\",\"ctaSubType\":\"main\"}'>May 18, 2025<\/a><\/blockquote><script async src=\"https:\/\/platform.twitter.com\/widgets.js\" charset=\"utf-8\"><\/script>\n<\/div><\/figure><p>After his glorious triumph at the 2025 Australian Open, where he retained his crown, Sinner was open in his admissions. <em>&ldquo;Having Mark here was maybe the best part of the victory.
