I've been doing some just for fun practices and rallies before I started playing a doubles match. My serves were great before the match, loads of spin and some aces + 95% of them were in. When the game started. I hit 4 double faults in a row giving them a break. So the question is, how do you deal with this Mental shift from fun practice and Serious Game. Every time I try to hit the ball in it goes out... P.S Don't say to think of the game as a fun rally... that does not work.
