Corentin Moutet has addressed his unusual choice to become a full-time underarm server, saying it works better for him than his normal serve.

World No. 122 Moutet is currently competing at the Chengdu Open in China, which takes place between September 20-26. The Frenchman faced home player Tao Mu in the opening round, winning the match against the World No. 573, 6-2, 6-2.

One of the most interesting aspects of his game during the match was his consistent use of the underarm serve. This is surprising because this type of serve is not often used in high-level matches as a legitimate strategy. Instead, players tend to use it as a one-off in order to surprise their opponent.

During his match with Mu, Moutet used the underarm serve around 6 times, with each one having quite a lot of spin on the ball. He won a fair few points from them and expressed his desire to use the serve more in the future.

"I’m working hard on it [underarm serving]. I think I have to do more. It's working better than my normal serve. So I think I should do it a lot. Maybe every point in the future," he said.

Although it is not clear as to whether he will actually use the serve on every single point, it certainly seems as though he favors the underarm serve. This may have come after an operation on his wrist in January meant he had to alter his style of play.

The 24-year-old was dealing with a broken tendon which meant he was unable to play his backhand with both hands in the second round of the Australian Open, which he lost to Francisco Cerundolo in four sets.

Moutet will face Miomir Kecmanovic in the second round of the Chengdu Open, so it will be interesting to see how much he uses his underarm serve in this match.
