Dominic Thiem has checked off another milestone on his growing list of accomplishments—an indoor hard-court title. In the final of St. Petersburg, the Austrian topped Martin Klizan , 6-3, 6-1.

It marked Thiem's first win over the Slovakia. 


This is the second hard-court title for Thiem and his 11th overall title (eight of his crowns have come on clay). He will move up to No. 7 in the rankings, passing Kevin Anderson in the Race for London.


Thiem will next play the Shanghai Masters.
