Well today, I played in my first tournament. I did ok. I won my first match 6-3, 3-6, and 6-3. But I lost 0 & 0 in my second match. This is where I screwed up in my matches. Sometimes, my opponent would hit a shallow ball, but I can't get to it in time. If I do, I have to drop my racket head down, stroke the ball, but usually, it goes too high and I hit it out. Also, when I played the second match, I had a problem with deep balls. With the deep balls, they were too close to me and I just couldn't hit the ball. I also want to know how I can get more pace on my ground strokes and serves. I usually hit my groundstrokes with a lot of topspin, and I hit flat serves. I also need tips on hitting backspin slices and volleys. I just need tips to improve on these problems. Thanks in advanced.
