Q: How can I get consistency in my swing, when I travel alot and and can play golf only twice a month? Bill Reid

A: The goal of all golf swings is to gain a correct, consistent impact. Unfortunately, you as well as most all golfers, have a consistent swing. The problem is that your swing produces an unreliable impact because it is out of position and requires corrections prior to impact that are usually athletic and timing related and are difficult to repeat. The easiest way to achieve a more repetitive impact is to either work on timing/tempo/rhythm/balance athletic issues that make recovery easier to accomplish or to work on the causes in your swing that have put you out of position in the first place and required you to have such an athletic recovery to find a correct impact. One way is to say you will keep your swing and work on the keys (timing/tempo/etc) that allow you to recover and the other way is to change your swing so the out of position parts are either eliminated or less severe and it becomes easier to find impact. There are unfortunately no free lunches. Changing a swing requires practice and the correct advice (sometimes hard to find) and the other requires working on your athleticism, strength, flexibility and balance. This is true whether you are a Tour professional or an average golfer.

Q: Whenever I am hitting practice shots from a tee box I can get myself easily into the right alignment and I hit the ball very well. It makes sense that because of the tee box, getting properly aligned is a breeze. But when I play from a regular tee or fairway etc. I am either right on or way off! I spend the remainder of the holes trying to figure out how to get back in the right swing. What is the best way to assure proper alignment on the course??
Thanks. David

A: The best way is to first put down the club face and aim it at the target. Then position the shaft so it is neither ahead or behind the club face. At that position, the end of the grip is telling you where to stand....directly center your body at the end of the grip. Stand with the grip in the middle of your pelvis and then grip the club and take your stance, being careful to keep the center of your body opposite the grip. With a driver, you will want to SLIGHTLY move your center to the right so the ball is played more forward in your stance and with a short iron you do the opposite so the ball is played a little back of center. These SLIGHT adjustments from center are only inches in size.

Q: On the putting green, I marked, lifted and cleaned my ball. I replace it without removing the coin and them accidentally moved the ball with my putter. Do I incur a penalty stroke?
Thank you, John Brandon, Corpus Christi, Texas

A: Once you replaced the ball it was in play whether or not the coin was removed (see Rule 20-4 (When Ball Dropped or Placed is in Play)). When you moved the ball with your putter you incurred a penalty of one stroke under Rule 18-2 (Ball at Rest moved by Player, Partner, Caddie or Equipment) and are required to replace the ball.

Q: All the players in my group saw my ball go into a green side bunker. We could not find the ball. What is the penalty and where do I play my next stroke from?
Larry Nicola

A: Once the five minute search period has expired the ball is lost and you have only one option; that is to return to where you played the last stroke and add a penalty stroke.

Remember when searching for a ball believed to be buried in a bunker, Rule 12-1 (Searching for Ball; Seeing Ball) tells us that we can use a club, rake or anything else in order to find the ball. This Rule goes on to say that if the ball is moved, there is no penalty; the ball must be replaced and, if necessary, re-covered.

Q: I got caught in the rain. now I have some small rust spots on my shafts. How do I clean them?

A: Tim - Thanks for your question on PGA.com.

To take care of those rust spots, make a trip to your local hardware store and buy a can of Never Dull. Rub the treated material on the shaft, let dry to a haze, and wipe with a clean towel. This should do the trick.

How important are grooves really? (photo: Getty Images)

Q: Does a golf ball really roll up the clubface, lets say a 9 iron struck from the fairway, or is the launch angle and the subsequent ball spin a function of the angle of the clubface at impact. I say the ball compresses, and leaves the clubface at the angle formed by the clubface, and the resultant spin a function of that angle, ball characteristics, and clubhead speed.

In fact, I say club grooves are unnecessary, however will make a concession they may help out of the rough.

Sid Dukes

A - Sid: It sounds like you have given this a lot of thought...maybe too much!

Launch angle with irons is determined by the actual loft of the club, clubhead speed, and spin rate. The main factor in determining the amount of ball velocity, backspin, and trajectory (height) in swing speed. The higher the swing speed, the higher the trajectory of the shot with any given loft.

With that said, the main function of grooves on the face of an iron is for alignment. Now I will agree (and so does the USGA) that the sharper, square grooves provides more "grab" (especially out of the rough) than provided by the old, conventional grooves. Thus, there is a subsequent rule change that restricts the design of grooves which will go into effect on the PGA Tour in 2010.

Hope this information helps.

Q: Dear David. I have been a golf professional for 20 and recently changed my golf swing to the stack and tilt swing.It has made a huge difference in my ball stricking.im off now for 3 months to asia to work on my fitness.which body muscles do you think should be strenthent for someone using the stack and tilt swing.regards and thankyou for your comments. Dave

A: Dave

The muscle groups you should focus on are the core region, Abdominals and Low back, Glutes, hamstrings and back. You need to isolate the glutes to make sure they are active and then incorporate them into single leg exercises such as squats and lunges. The core should be trained standing as well as lying on your back.

The single leg exercises are important to stabilize your left leg during impact and supporting your body during the stance.

Q: Hello, David,

My swing/score has became terrible If I exercise for physical strength like dumbbell on the day of playing or the day before. My question is professoinals exercise for physical strength how many days or hours before the game? And how come they relieve their muscles' fatigue if they exercise in the morning of game day?
David, thanks a lot for your kindness in advance.
Myung Kyoo Choi

A: Myung,

Some people respond differently to training the day of or the day before a tournament. You need to determine what works best for you. The big key is consistency and proper training. Keep your routine the same, when you change your routine or take time off you lose the consistency and increase chance of soreness and fatigue.

Most professional golfers train their core muscles abdominals and low back, legs and stabilizing muscles. The day of and day before tournament is usually more power and lighter than normal.
