hahaha, Johnson hit a ball down the line that was out, Smith called it out and Johnson started acting like a little baby and walked all the way up to the net then argued with the umpire. On the next point, Smith hit a clean winner down the line, Johnson walked over to the ball and instead of hitting it over the net to Smith, he dribbled into the net and made Smith walk up to the net and grab it... You're right, when he gets rattled he is a tool..
I've played tennis most of my life and that is the most frustrating part about the sport. So many bratty, spoiled babies! Which makes me cheer for people like Smith even more
