 Batter in baseball has an advantage of knowing about where you're going to throw it, whereas the receiver in tennis does not. But he gets to stand, right, if it's 60 feet, and then you add another 30 or whatever from where he's serving from, and 30 from where you're receiving from, you have 120 feet to react. So you have twice as long, a little more than that, to react as a tennis player.
