That is excellent advice Chance.
It sounds dumb but I try and say HIT BOUNCE HIT on every stroke (except serves, volleys). It really really works to stay on the ball better. It also keeps me focused and have better anticipation.
The head is key to your swing path going a tad astray at the last minute. You could have too much or too fast upward brush when you frame the ball. concentrate on extending out to the target more. This will help keep the racquet head longer in line with the ball.
Practice going through the ball. In other words, practice keeping your racquet going in more a straighter line before cutting off and up. You can email me for specifics.
