Washington DC (Tennisfiles) – 18-year old German phenom Alexander Zverev continued his impressive run with a 2-6, 6-3 6-4 win over Ukranian Alexandr Dolgopolov.

The win marked his second straight victory over a top 100 opponent for the 96th-ranked Zverev. In the previous round, the young German defeated 5th seed and #14 ranked Kevin Anderson of South Africa.

Zverev turned pro in 2013, and at 6’6 with a powerful game, the 18-year old has the potential to be one of the best players in the world.

Mehrban from Tennisfiles asked the German phenom about his run through the draw in Washington DC and his success at such a young age:
