It sounds like you are slicing the ball (not pushing shots). The first thing and easiest thing to check is your grip as we want to make sure you aren't playing with a weak grip that could be keeping your clubface open. Check to make sure that the Vs that form between your forefinger and thumb of each hand are aligned parallel to each other and are both pointing somewhere between your right ear and your right shoulder. If your grip is solid and you are aligned square to your target (and your shoulders are not open) then we need to get you working on some swing plane drills to get your golf club down to the inside of the ball.
I'm going to give you a couple drills here to get started on. Give them a try for a week or so and see if you don't start to see some improvement.
Description: The Swing Plane Poles Drill helps diagnose an outside-in or inside-out path error as the cause for the slices (outside-in) or pushed shots (excessively inside-out) .
1. If you are able to determine if your swing is too far inside-out or if it's too far outside-in coming into the ball, driveway poles are very usefull.
2. If you are swinging too far inside-out coming into the ball place a pole just outside your ball and twelve inches forward on the same plane as your shaft at address. Avoid hitting it after impact.
3. If you are swinging too far outside-in, place a pole just outside your ball and twelve inches back. Avoid hitting it on your downswing.
Description: The Dropping Drill is designed to help those that chronically slice the ball because they come over the top. It teaches how to get the club down to the inside and on plane.
1. Start with a mid or short iron at first. As you get comfortable this drill can even be done with your longer clubs including the driver. Go ahead and set up to the ball as you normally would and swing to the top of your backswing.
2. From here, let your arms feel like they are free falling straight down. While keeping your back at the target allow your club to drop all the way to the ground. You should make a nice "thud" sound with your clubhead when it contacts the ground. It should hit the ground approximately between the ball and heel of your foot. The key is to not let it get in front of your toes.
3. From here, again, don't move your back and bring your arms back up to the top of the swing. Repeat the process a second time so that your club dumps into the ground again at the same spot. On the 3rd repetition when your arms and club start to drop and reach about waist high, then turn your back and shoulders away from the target. Be patient to make sure you start the arm drop first before you start turning towards your target.
4. With enough repetition with this exaggerated drill you will learn to drop your club down on an inside plane.
