Carlos Alcaraz's prematch warm-up is intense 😳
the energy this guy could understand why.
This is Mike, his defending champion.
Calories as he burned before he even plays the first ball
in the warm-up.
It's amazing.
And it's something that some people that don't see all
of this may take for granted.
I mean, this is just the last tiny percentage
of what he does.
Ruffle-like, of course.
