I've been researching this for quite some time and have finally reached the conclusion that my tennis (I play frequently and is currently 5.0, formerly college Div1 level) is basically capping my golf game. Right now in golf, my handicap is about a 7 and typically get in 1 round a week and 2 range sessions. Since I picked up golf about 6 years ago, I've been consistently working on the game (studying golf swings, doing drills at the range, short game, putting etc.) and have a fair good understanding of the golf swing.
I understand there are many similarities between the golf swing and tennis strokes, but what I have found are the following inhibitors by tennis on golf:
1. Tennis players with open stance on their forehands rotate their hips laterally from right to left, not transferring weight forward. If this is translated to the golf swing, this causes the OTT move and lack of weight transfer to the left side. It took me about 3 months of drills recently to "control" this early and fast hip rotation, but still requires regular maintenance and continuous focus when I am playing a round. The minute I forget to focus on this during a round, my right arm dominates and major slice...often resulting in a couple of doubles or even triple in my round as this tends top happen at the worst moments (tee shots!)
2. Tennis players are constantly on their toes...again, when translated to my golf swing, this caused me to regularly shift my weight to my toes/balls of my feet on the downsing resulting in the OTT move/shank.
3. Tennis (like most sports) is very much a reactive sport. I still have not found an good mental cues to reverse this to golf.
Other research data points:
1. There have been a number of current and retired golf pros that play good golf:
Ivan Lendl (I think he even qualified for the Senior Tour)
2. Mardy Fish-current pro and scratch golfer
3. Pete Sampras
4. Rafael Nadal...
And so, here is the key point about these tennis pros...they all play tennis opposite to their dominate tennis hand. Lendl and Fish golfs left handed. Nadal who plays tennis left handed, but golfs right handed. I remember Lendl mentioned once that his right side was so dominant, the only way to get the pulling sensation was to play left handed.
Right now, my frustration is that I feel I have reached the ceiling in my golf game placed on by my tennis game and the only way to reach my potential in golf is to start over and play left handed...which I am willing to do, but would appreciate feedback/advice from anyone who has reached the same conclusions I have.
All thoughts appreciated.
