Second seed Dominic Thiem mounted a superb fightback to beat promising youngster Alexander Zverev in the opening round of the Rotterdam Open on Wednesday.
Fresh from his victory in Montpellier last week, 19-year-old Zverev very nearly proved too hot too handle for another top-ranked player after taking the first set 6-3.
But Thiem, currently ranked eighth in the world, is no pushover, and the Austrian managed to mount a superb comeback in the last two sets to secure a 3-6, 6-3, 6-4 victory.
Zverev's older brother Mischa also made the trip to Rotterdam this week and also faced a very tricky opponent first up in fifth seed Grigor Dimitrov.
Like his younger sibling, Mischa also managed to take the first set, but like Thiem, Dimitrov was also able to recover and post a 6-7 (4-7), 6-2, 6-4 victory.
