Jannik Sinner secured his fourth title of the season at the Vienna Open, although the final was anything but straightforward. He won 3-6 6-3 7-5 against Alexander Zverev.

The four-time Grand Slam champion won the Vienna Open, but it's what he said in his victory speech that caused a stir.

Top seed Jannik Sinner brushed aside Alexander Bublik to progress to the Vienna ATP semifinals on Friday. Sinner made it three from three in Austria since retiring injured from the Shanghai Masters earlier this month with a 6-4, 6-4 win over the eighth-seeded Russian-born Kazakh.
