Hitting shots from the rough at TPC Scottsdale

Published

on

Before players arrived on site for the Waste Management Phoenix Open, I hit a few shots from the rough at TPC Scottsdale to see what the players have to deal with. With the help of Trackman, I recorded how different lies in the rough produce different numbers and ball flights. As you’ll see, certain lies in the rough greatly affect the outcome of the shot.

Let’s jump right in and have a look at the length of grass we’re going to be working with. As an instructor at TPC Scottsdale, I teach just off the right side of the No. 9 fairway, which will be in play for the tournament. The PGA Tour was targeting 3.5 inches of rough, and by the picture below, the grass was already at tournament height at the time of my experiment.

Now that we’ve got some solid rough to work with, let’s talk about how the grain of the grass considerably affects the outcome of the shot.

FlierLie

Grass can be mown or brushed to cause grain, and it can also naturally grow in different directions. Shiny grass lays away from you, dark grass lays toward you.

With the help of Trackman, let’s take a look at what happens with the different lies pictured above. The idea for my experiment was to make very similar swings, specifically in club speed, using a 7 iron from the various lies to see how much the grass can affect ball flight characteristics.

Fairway Lie

First, let’s look at a standard shot from the fairway. A good rule of thumb on spin with your irons is a 1000 rpm for each number. A seven iron should have roughly 7000 rpm, an 8 iron 8000 rpm, etc. In the photo above, you can see the numbers for my normal 7 iron.

Thick lie, slightly into the grain

Now that we know what a normal 7 iron looks like, let’s take a look at our first lie in the rough. This ball is down in some thick grass that is slightly into the grain. I added a pen to the photo for some scale.

That’s surely some deep sticky grass, and as you can see from the Trackman numbers below, 87 mph of club speed produced a shot that carried only 87 yards and had just 1300 rpm of spin.

This kind of lie is brutal to hit from. As the club gets into the grass, the hosel of the club has a tendency to contact the grass first and slow down the heel of the club down, causing the club face to close. The only thing you’ll be able to do is hit a low line drive with little spin that runs slightly more than a normal shot because of the greatly reduced spin.

Higher club head speed and strength make a huge difference here — more speed has almost a one-to-one ratio to carry. More carry doesn’t necessarily make the shot easier to stop on the green, but it gives you the ability to fly the ball a greater distance.

Catching a break, the down-grain lie

Let’s take a look at what happens when you get the ball to land in some down grain grass. You can see the lie below. A tire track matted the grass down in the direction I’m hitting the shot. This rye rough is so dense the ball doesn’t sink to the bottom of the grass. It rides high, giving the player a fighting chance. Check out how much difference a down-grain lie can make compared to the shot out of the thick stuff. It carried 80 yards farther!

Digging into the numbers a little deeper, a couple things stick out to me.

First, even though the club speed is similar, the long, down-grain grass will take some speed off the ball. I got 115 mph of ball speed from the down-grain lie and 121 mph of ball speed from the fairway. My guess is that a couple of blades of grass got stuck between the face of the club and the ball. Like a baseball pitcher throwing a change up, shots hit from the rough move a little slower.

Even though the ball was traveling 6 mph hour slower, however, the low spin rate caused less friction in the air and, in turn, helped the ball fly the same distance as a shot from the fairway. With less than half the spin rate, however, it won’t stop nearly as quick as my stock 7 iron with 7200 rpm of spin. Plan accordingly.

When you’re watching the Waste Management Phoenix Open this week and you see someone play a shot out of the rough, you’ll have a much better idea of what is happening.

Things to remember when playing shots out of the rough

  • When you reduce spin on any shot, all things being equal, the ball will fly farther.
  • There is an art to reading how the ball is sitting in the grass. Take note of the grain of the grass and try to gauge how much grass is going to be caught between the face and ball at impact. More grass in between the ball and the club means less speed and less spin.
  • Don’t forget that a flier can be an advantage. A good example is trying to get the ball on a par 5 in two shots from some down-grain grass. Less spin can add carry and more roll once the ball hits the turf.

    We need more articles like this to explain to weekenders what really happens with their game and why they score so poorly.

Kelley: Should a Tour player’s swing be the pattern we copy?

Published

on

PGA Tour players are the most gifted golfers on the planet. Their ball striking ability is remarkable to the average, even scratch, golfer. With the time to practice all day, usually perfecting their imperfections in their own swings, why are PGA Tour players’ swings always the model we seek?

Look at the progression and expectations in other sports played recreationally. If you start playing Tennis, you don’t expect to serve as fast and accurate as Rafael Nadal. When joining a gym, do we look and replicate the times and bodies of Olympians? However, in golf, players seek the worlds best trying to emulate them. Examining this idea, could this actually be detrimental?

Let’s start with the speed differential. The average PGA Tour driver club head speed is 113 mph. The average male amateur golfer driver speed is 93.4 mph. The average handicap for the male golfer sits between 14 and 15. Below is a chart from Trackman showing the distribution of clubhead speed among male golfers.

*Trackman research shows there is a direct correlation between clubhead speed and handicap.

Speed is mostly a natural talent developed at an early age. It can be enhanced with speed training, gym work and even lifestyle changes. ?With such a differential in speed?, wouldn’t players first be better served focusing on center contact with the most efficient route to do so? This can include modeling simple looking swings.

Besides the speed differential, the world’s best golfers all have unique swings that have been perfected over time. Take for example the top ten players in the world. Different swings with different match-up moves throughout the motion. They have made it work for themselves with countless practice hours. Usually time the average golfer doesn’t have.

A main example would be Rory McIlroy, often a sought out golf swing among students. Here is a quote regarding his swing swing sequence after visiting the Titleist Performance Institute Center. “At the start of McIlroy’s downswing, his left hip spins violently counterclockwise, as it does for every elite, long-hitting player. but then, and only with the driver, Mcllroy makes a funky move you could not teach. a moment before impact, his left hip suddenly changes direction and jerks back, clockwise, and then rotates again.”

With the average golfer on a time constraint?, golfers could actually look at what the greats do the older they get in their careers. The swings become more simple, using their instincts to get their body in efficient and more teachable positions. This is usually in their set-up then backswing, with less excess movement for an efficient strike. Take for example a young versus older Ben Hogan. (Picture below)

Below is another example of a young Jack Nicklaus compared to an older Nicklaus later in his career.

This is in large part due to the concept that less can be more at times. Unfortunately in golf, all to often players are told to do more with their swing, only to jeopardize center contact even seeking vanity over function.

A concept that could be beneficial is next time you want to work on your swing, focus on efficiency and minimizing the ?motion for center contact and a better face/path relationship. Then you can build. Rather then taking a bit from a Tour player’s swing, understand how your body should move to achieve your desired ball flight. Once you have a foundation, then add speed and your own DNA to the swing.

The argument could be made the opposite should be taught for aspiring junior golfers, especially the way the game as going. This article is intended to open a discussion and perhaps change the view of how the golf swing is being taught based on your skill-set and what you are trying to get out of the game. Also, what may be teachable and not teachable. You can change swings with concepts alone.

Clement: Why laying up = more power

Published

on

You have been there before — you can’t get over the hazard on a par 5 and decide to lay up and take the club you need for the distance and the ball makes it into the hazard after you took this smooth swing that smoked the ball 15 yards farther than you expected? We uncover the mystery right here!

Kelley: Simplify your swing with the hammer drill

Published

on

Regardless of your handicap, a simple hammer can teach you how to efficiently address the ball, start the swing and then put your body in a dynamic position at the top. If you can hammer a nail, there is no reason you can’t simplify your swing. This drill can also change the parts in the middle of your swing you have been struggling to change.

To start, grab a hammer with your trail hand as if you are hammering a nail into a wall in front of your body. You will notice how this instinctively gives you a slight tuck of the trail elbow and drops your trail shoulder below the lead with angle in the trail wrist.

Once gripping the hammer, move the weight of the hammer as if hammering a nail. This will give you the feel of the takeaway.

From here, the golf swing is no more then a lifting of the arms as the right arm folds and the body goes around a bit.

From this position, holding your spine angle and placing the left hand on the right hand will pull your body into a coil or “turn”. This places your body in a position to efficiently swing the golf club back down to the ball.

A great way to combine the hammer drill with a golf club is to hold a hammer on the grip of the club or tape the hammer down the middle of the shaft. Start with just your right hand on the club and make slow swings.

Once you have practiced this a few times, the hammer can be removed and this feel can be integrated to a normal golf club. To continue this feel, simply turn the clubhead in as if you are hitting the ball with the toe of the club (below picture). When turning the club like this, the center of balance goes more to the clubhead, helping replicate the actual hammer feel.

What’s great about this drill is that the actual task is driving the technique. Rather than being thoughtful of several technical positions in the golf swing, replicating the instinctive motion of the hammer will put you in the proper positions. This drill will also help you place your focus of attention on the actual club, which is often overlooked.
