Stan Wawrinka vs Hugo Gaston prediction

Wawrinka has registered some solid results on the ATP Challenger circuit. The Swiss seems to be enjoying his tennis at the moment and will be fancying his chances in the final. He has yet to drop a set in Rennes.
Meanwhile, Gaston has worked diligently to achieve his results this year. The Frenchman deserves a title for his efforts, but will need to raise his level against Wawrinka. He has a steady all-around game and likes to play long rallies on the court.
Wawrinka has had the answers in tricky situations this week. The three-time Grand Slam champion will be up against a tricky opponent, but should be able to use his experience and come out on top.
Pick: Wawrinka to win in straight sets.
