It was a breakthrough weekend for two of the most talented youngsters on the ATP Tour, as Alexander Zverev and Lucas Pouille both lifted their maiden tour titles on Sunday.
For 19-year-old Zverev, it was a case of third-time lucky.
The German had already lost two finals in 2016, but he finally got over the finish line in St. Petersburg, outlasting US Open champion, Stan Wawrinka in a topsy-turvy final.
Zverev took the opening set 6-2, but Wawrinka hit back to seize the second 6-3.
The world number three made the first move in the final set, opening up a 3-0 lead, but Zverev showed commendable mental strength to fight his way back into the contest.
It was the more experienced Wawrinka who cracked late on, dropping his serve at 5-5, leaving Zverev to serve for the title.
The teenager confidently took care of his own deliveries, sealing the deal with one final forehand winner after 2 hours and 23 minutes.
Victory in Russia lifted Zverev to number 24 in the world, matching his career-high ranking.
Alexander Zverev wasn’t the only first-time titlist on Sunday; Frenchman, Lucas Pouille also celebrated his maiden success over the weekend in Metz.
Fresh from his quarter-final showing at the US Open, the 22-year-old produced another fine week at the Moselle Open, finishing things off with a 7-6 6-2 victory over top seed, Dominic Thiem.
Thiem raced to a 4-0 lead in the opening set tie break, but Pouille held his nerve, winning 7 of the next 8 points to snatch the set.
He controlled the match from there, breaking twice in the second to ease to victory.
Pouille has now got the better of Thiem in their two meetings, and this latest victory has lifted him to a career-high number 16 in the world.
