Milos Raonic feels that the game's bigger players are evolving

Canadian Milos Raonic, who hit 32 aces to defeat John Millman and reach the third round of Wimbledon, says the game’s bigger players are starting to evolve—and serves are going to continue getting harder and harder.

Going into the tournament, Raonic has 6,275 aces for the season. The Canadian has served as high as 155 mph and says it's going upwards.

“I think it probably will be humanly possible," said Raonic. "The way you're just going to have to see and look at it is physics-wise, you can only hit a ball from a certain angle so hard before it's not going to drop in time.

“To serve hard, it has to be flat. So either you're going to have a guy that's extremely strong hitting from a higher point of contact, or you're not going to be able to do it with much spin. But there will be some progress and some kind of development. But maybe before the margins, the steps were higher, but now the margin is just getting smaller because physics and gravity can only allow for so much.”

WATCH—Daily Serve from Day 3 at Wimbledon:

The 27-year-old Raonic is 6'5", and he believes that taller players are getting more efficient and stronger. It has been historically difficult for the super tall men to win a major, but slowly, they have found ways to bend down, move to the right or left quickly, and forward toward the net.

“It's good," said Raonic. "I think the difference you see nowadays from the tennis I have seen previously from big guys—and I consider a big guy 6'5" and above, I'm sort of on the bottom edge of that, because a lot of the guys are taller than me—everybody used to train the way a tennis player should train. People didn't used to sort of make individual training programs.

"I think the big guys realized, 'Hey, this is what we need to do to get the most out of ourselves.' You see guys moving more efficiently. You have Nick [Kyrgios], who's incredibly athletic. You have [Juan Martin] Del Potro who I would say is one of the better movers, especially laterally.

"You have guys that are getting better because they are looking for programs and techniques that are going to suit them best.”
