Corentin Moutet sliced in an underarm serve on match point and sealed his first-round victory at the Australian Open on Sunday when Tristan Schoolkate floated his forehand return too long. The crowd at Kia Arena booed loudly but the No. 32-seeded Moutet didn't flinch, later saying he did what he needed to do to complete the 6-4, 7-6 (1), 6-3 win. The underarm serve is within the rules but is rarely used in the highest ranks of men's tennis, particularly on match point.
