I've switch to a western grip and have been taking a lot of points from the baseline lately (good news). My opponents have been hitting short balls - either as a weak return, or to try to bring me to the net. I run up to meet the ball and seem to flub it because I overrun the ball or just don't have the skill to hit it on the run. I can't make myself split step before the shot. I tell myself that I don't have the time. How do you handle this?
