World number three Stan Wawrinka stormed back from a set down to beat German qualifier Mischa Zverev 4-6 6-3 6-3 and retain the men’s title in Geneva on Saturday.
The top-seeded Swiss looked frustrated early on as the number 33 ranked Zverev broke his serve and went on to take the first set.
In front of a partisan home crowd, Wawrinka jolted into life and raced to a 3-0 lead in the second.
He sent fizzing forehands across court and down the lines beyond Zverev, taking the set in the process.
Wawrinka, winner of the French Open in 2015, dropped serve once in the final set but broke Zverev three times.
He then secured the title with another ripping forehand for his first tournament win of the year as he prepares for another Roland Garros campaign.
The French Open gets underway on Sunday.
