Yes, men's tennis. Are you under the impression that aces are very common? And of all the aces hit, not all were literally unhittable, unless you want to call a whif in baseball unhittable.
How heavy is a racquet? A bat? How far back can you move in the batters box? Don't you hate when you swing for a ball outside the strikezone in tennis? Etc. I'm not a baseball player or fan and have no idea what challenges a pro batter faces, but I'm not going to make assumptions. Even if you have some experience, you don't have the level of experience necessary to judge this, and there is always the chance that you could be incorrect regardless of experience.
