Promising German 19-year-old Alexander Zverev won his first tour title Sunday Sep 25,2016, beating U.S. Open champion Stan Wawrinka in a tight battle in the St. Petersburg Open final.

Zverev took the first set before Wawrinka responded to draw level.

The German was a break down in the decider, but fought back to win 6-2, 3-6, 7-5.

Zverev becomes the first man to beat Wawrinka in a tour final since 2013, snapping an 11-match win streak in finals for the Swiss star, who had been trying to win back-to-back titles in his first tournament since the U.S. Open.

The loss also ends a 10-match unbeaten run for Wawrinka.
