on the serve one choice is to drop down on the start
on the follow through drive up and out
Sinner did get a knockdown of Monfils
going low to high and finish on the hit side
on the two handed backhand finish get both elbows up
on the jam serve pull the front leg away from the ball
track it all the way in
everyone needs a medical timeout
drive the slice out
on the open stance hit keep both toes towards the net and rotate
rotate your shoulders and hold the racquet
at the Open all lines on every court were called electronically
when you use your legs spring up and in
on your volley move your feet through the hit
when the lob goes over your head chase it down
