I just lost a match where I was blown out the 1st set, down a break the 2nd and got back on serve and was up 40-15 at 5-5 where I hit a great approach down the line forcing my opponent to pop the ball up giving me an open court that I hit in the middle of the net. After that I lost the game and he served out the match. Throughout the match I'd pull him out of the court and then miss the shot into the open court way too often. I can remember 5 or 6 points where I did that. This is something I've noticed I do in real matches I don't do when in clinics or during private lessons. I'm trying to win the point so I think I'm looking to see what the other guy is doing so I know whether to go behind him or not. Seems like I take my eye off the ball and lose timing when I'd going this so I end up missing the shot. What should you be thinking when you get an "easy" shot and have a wide open court? Ones like the shot Roddick missed vs. Federer in the 2009 Wimbledon final at 6:20. Do you just decide as your running up to the ball where you're going to hit it? How much attention to you pay if any to your opponent's position?
