Bah give the kid a break....ok I'm doubtful he took games off Polansky as well but who cares, no need to attack him endlessly.
Anyway, Winnipeg.....as I said, my serve is very technically flawed as well but I'm still able to generate a bit of pace into it. I've been struggling with my 2nd serve lately so I went down to some shitty courts round the corner from me this morning and decided to make a video for you
As you can see, I don't use my feet nearly enough, and as such my first serve can sometimes have a very low %. Probably not enough hip rotation as well. Unfortunately I never had lessons when I was younger and developed a lot of bad habits, it's almost impossible to totally change my serve at this stage.
