on transition get your racquet up and in front of your body
track the ball all the way in
get the back knee below the incoming flight path
fingers into the sky facing sideways
keep your eyes up and see the hit
as you track the ball in slot your head and keep it there for a beat past the hit
back for is inside the front foot and angled in– presets the shoulder and hip rotation
you want to go up and out before you rotate
Medvedev has a great quick to the finish
on the serve follow through bring the hitting hand to the opposite pocket– hug yourself
see the contact — track the ball in
up and out on the finish
before you go over the shoulder you must still go up and out
you need to get the back knee below the incoming flight path
pull the step in leg in and away to create the space needed to hit
