Blew another match last night to someone I should have beat. I'm having trouble with a lot of these 4.5 players who don't give you much pace to hit with. I can't find a rhythm and before I know it I'm pushing the ball back. But, by staying steady I managed to win the first set 6-0 and was up 4-2 and serving. Had game point, long rally, she hit a nice hard shot for once and it took me by surprise and I missed the return. Lost the next two points, including one on a double fault. Came back and broke her. Served for match. Had match point at 5-4, jumped into a backhand too close to my body and hit it long, then lost the next 10 points and the set. Lost the last set 6-1. I'm getting so frustrated. In practice, I can hit the ball nice and hard and I'm relaxed. Then I get into these matches against people I should beat and I get way too tentative and can't hit out on it, and since I'm a better player when I'm playing agressively I just fall to pieces. Anyone have any tips for calming yourself mentally so you can play under pressure?
