Sports where you serve a ball include tennis, volleyball, badminton, table tennis, and pickleball. In tennis, the serve starts each point, while in volleyball, the serve initiates play and is crucial for scoring. Badminton and table tennis also require a serve to start each rally, and in pickleball, the serve is used to begin each point as well.
You can hit an underhand serve in tennis; however, the overhand serve is more effective because it is more powerful. That is why you don't see the underhand serve used much.
