Italian top seed Jannik Sinner has produced a spirited comeback to defeat Germany's Alexander Zverev 3-6 6-3 7-5 in the Vienna Open final to secure his fourth ATP Tour title of the season and his second triumph in Austria's capital.
On a day when the Italian, already one of the sport's greats at just 24, prevailed, there was also a reminder at another ATP 500 hard-court event in Basel that he could soon be challenged by brilliant Brazilian teen Joao Fonseca, who won the Swiss Indoors title.
With his 6-3 6-4 win over Alejandro Davidovich Fokina in the title match, the 19-year-old Fonseca became the third-youngest ATP 500 champion in the series' 16-year history.
