We are proud to announce that our 2nd video - Short Game Secrets Drills and Games - has finished shooting and is currently in editing. This video, as the title suggests, will give about 20 drills and games for making more putts and about 20 more for wedge play.

Nearly 40 drills and games James and I have chosen to show you that we use in our own teaching of every level of player.  These drills are designed to improve the quality of your outcomes, not necessarily just drills on technique. James and I are comfortable knowing that the short game is a problem with multiple solutions and technique change could need to be very personal. These drills will touch on technique but most are geared toward measuring your current techniques ability to perform and score a set of tasks.

The putting drills cover the putting skills of targeting, touch and start line. Technique and games that require different types of makes to play are also included to help a player visualize more than one way to make a putt.

The wedge drills cover the wedge play skills of spin control, trajectory control, and distance control. Just like the putting drills, the wedge play drills will touch on technique but they're focused on making your practice time more fun and productive.

Pre-order sale pricing of $19.99 starts today and goes till March 17, 2014 at 30% off the normal price and can be purchased here: http://shortgamesecrets.tv/products/drills-and-games

Video should be ready to download in 2-3 weeks and links will be emailed out once available.

Stay tuned for an upcoming trailer in the next few days.

Who has the best wedge game on tour? I don’t think many people would look past Tiger as having the best wedge game on the PGA Tour yet in 2012 Tiger was officially average on all shots up to 100 yards from both sand and grass. In fact, he was average in all the sub categories also, barely gaining or losing any strokes to the average PGA Tour player performance in these categories.

Wedge play has been separated into 5 categories; 0-20 yards, 20-60 yards, 60-100 yards and sand shots from 0-50 yards & 50-100 yards. In the video accompanying this blog I've taken a look at the leaders in the three 'from grass' categories to identify a few points that enable them to have led their respective categories, I think you'll see that the styles are very different and lend themselves to a particular type of shot which offers a partial explanation as to why they excel in some areas yet struggle in others.

The leaders of the 5 categories were:

0-20 yards: Charlie Wi

 20-60 yards: Trevor Immelman

60-100 yards: Brian Gay

Sand 0-50: Chris DiMarco

Sand 50-100: Sung Kang

I hope you enjoy the video

We are excited to be offering a Vokey Wedge of your choice as a prize as a thank you for your support in the successful launch of the Short Game Secrets project.

Why Vokey? Well the Vokey SM4's led the wedge testing discussed in the All Wedges Are Not Created Equal blog, generating amongst the highest levels of spin from the fairway and retaining the most spin from the rough. As discussed in the Science of Spin blog the surface between the grooves is a large factor in spin creation with the modern wedge and Vokey have the process perfected.

"The Rules of Golf allow for surface roughness within the impact area of a golf club. The micro-edges created on the face of Vokey Design SM4 wedges using our patented Spin Milled process are one example. Parameters set forth by the governing bodies dictate the maximum allowable roughness across a specified surface area as well as the maximum allowable depth of any markings. When compared against alternative milling processes, Spin Milled wedges have approximately three times the roughness across the specified surface area with similar milling depths. In Titleist R&D testing, this equates to 22% more spin on partial wedge shots using Spin Milled wedges." 

There are three ways to enter:

So there you go, the first of many competitions designed to say thank you and enhance your short game at the same time. You need to be in it to win it!

As a follow up to the All Wedges Are Not Created Equal blog that measured the variance in performance between a number of manufacturers wedges it's worth delving into the subject of spin generation a little with a brief review of the USGA literature that is freely available and commonly held beliefs.

What are the technological factors that effect spin?

- The roughness of the flat surface between the grooves

- The sharpness of the top edge and/or the type of grooves

- How far apart the grooves are positioned

- The depth of the grooves.

The interaction that creates spin is quite simple, it is one that creates the most friction and therefore the most spin. At lofts of 40º and under the interaction is mostly sticking and no slipping occurs, the friction force is the same with both smooth and rough surfaces according to Chou, Liang and Yang (Science and Golf II: Proceeedings of the World Scientific Congress of Golf II)

This leads us on to the research conducted by the USGA over a period of years prior to the rule change regarding groove technology, available here USGA Research. The interim paper notes that prior research has found that there is no difference made by groove configuration and face treatment and proceeded to test both the U & V groove types in dry conditions concluding that there was no difference once again.

However during the benchmark player testing there was found to be a difference between modern equipment and old V grooves and balata balls that spun more that any modern equipment combination. From the rough however it was found that the U grooves had the potential to spin MORE than from the fairway! 

The study also concluded that the edge radius or the 'sharpness of the edge' is a contributor to spin but the closer towards a V Groove shape it became the significance reduced to almost none.

Groove spacing was also found to be a significant contributor regardless of groove type.

The type of milling was found to have no significant influence on spin rate from the rough except for an extremely rough surface.

So the question remains as to what was responsible for the often huge performance gaps for spin generation between wedges included in the testing from the previous blog entry. If all the above were bulletproof it would fair to say the performance should be very similar throughout when using the same player, in the same conditions, even allowing for some technical variance. 

We're excited to be planning some testing next month that will include the use of grooved and non grooved wedges from a variety of lies and distances. While it will not be as scientifically sound as the USGA's (expensive) testing it should provide some insight into this fascinating topic in the real world sense.

Using the data collected from a wedge testing session last summer I’m going to illustrate a few key points that might help improve your wedge game through choice and maintenance of equipment.

A group of wedges (56º) from a variety of manufacturers were tested from a distance of 70 yards from two types of lies, tight fairway and 2 inch rough. Spin rate and launch angle were measured using a Foresight GC2,  the wedges required a minimum number of 5 shots from which the averages and standard deviation were taken. A spin retention value was also calculated to measure the diminishing performance from the rough.

The average spin rate from 70 yards on a tight lie was 7130rpm but the variance went from a low of 3573rpm to a high of 8910rpm, as you can see from the mean average the drop in performance from a low performing wedge was significantly greater than the gain from a high performing wedge. The higher performing wedges tended to have a better quality of milling, score lines and extra grooves to provide that advantage.

The correlation between launch angle and spin rate was somewhat linear, for example the lowest spinning wedges were around the 4000 mark and launched at 32º. Wedges spinning at 5000rpm launched at 30º, 6000rpm at 28º all the way to the high 8000’s launching at 24º. Club delivery was very consistent throughout illustrating the importance of friction to launch.

Spin retention from the rough was quite revealing with the average wedge maintaining 30% of it’s fairway spin number when being hit from 2” rough. The top performers in this category maintained approx 50% while the poor performers only maintained approx 20%.

Combining these two parameters gives a good idea of which wedges are the overall top performers and should you get chance to test wedges on a launch monitor of some kind are two measures I’d recommend looking at.

We also conducted a test comparing year old wedges of the same type versus brand new, the old had seen a couple of dozen rounds and some range use but nothing excessive. The spin loss and related higher launch was significant at over 50%.

If you’re going to work towards a tour calibre wedge game it’s vital that you equip yourself properly, if you don’t it will be impossible to control launch, spin effecting trajectory leading to poor distance control.
