Jannik Sinner fought back from a set down to claim his fourth title of the season with victory over Alexander Zverev in the Vienna Open final.
The top seed, who is currently on a 21 match-winning streak on indoor hard courts, battled through early hamstring cramp to seal the 3-6 6-3 7-5 win in just under two and a half hours.
It marks Sinner's second title of the month, having won the China Open at the start of October, while he also added to his Grand Slam haul with victories at the Australian Open and Wimbledon earlier in the year.
