Is The USGA's Groove Rule Working?
I read with interest a brief overview of some statistics from the Farmer’s Insurance Open at Torrey Pines, and how they might have been affected by the new USGA rules governing grooves enacted by the PGA Tour this year. If you remember, the point of this change was to address the declining effect of hitting fairways on scoring on the PGA Tour. The USGA contended that the milled groove technology, with the precise sharp edges, was making shots from the rough as easy to stop as historic shots from the fairway. They felt like, if they reduced the effectiveness of grooves, that golfers would retreat some from their bomb–and-gouge approach to being more concerned with hitting fairways so they could control their approach shots.
Is it working?
Through four events, comparing this year to last, here are some stats that could be meaningful:
1. Average driving distance is down by 6.7 yards, so that looks good right? But haven’t at least two events been played in very wet sloppy conditions? Hmmmmm, could that be the real culprit with this stat?Now, to me, here’s what’s interesting about the next three stats that were covered in this GolfWorld article and chart.
1. Approaches from the rough – 50-125 yards. According to the USGA, this is precisely what the new groove rule was supposed to address – the ability to stick it close from the rough. Well, accuracy from those shots actually improved, from an average result of 28’7”, to 26’9”, or almost two feet! Hmmmm, doesn’t look like the new grooves are giving them that much trouble, huh? But there’s more.But I know . . . where the new grooves really gave these guys fits is in scrambling, right? Hitting those tricky little shots around the greens, where lack of spin is sure to put more bogeys on the card. That’s where this new groove rule would show its teeth for sure, won’t it?
Well, Scrambling Success (inside 30 yards) actually improved, too. According to this statistical review, it improved from 26.75% in 2009 to 30.30% this year so far.
So, let me get this straight, the USGA changed the rules on grooves so that these top players would have a harder time hitting greens from the rough, getting up and down would be tougher and they’d have to hit more fairways. But shots are ending up closer to the hole from the rough, and scrambling is improving.
Wouldn’t it be great to be a fly on the wall at USGA headquarters and be able to hear how they are processing this so far?
The lessons learned.
But The Wedge Guy is all about improving your scoring, so what can you take from this?
Well, first of all, compare your fairways hit to tour pros and cut yourself some slack. These guys only hit the fairway 6 out of 10 times. They find themselves in the rough 5-6 times per round. I think you should set your sights higher because you don’t hit it that far, and you are not that good from deep gunk.
Secondly, these guys average putts of 30 feet or less from the rough, inside 125 yards, so what should your fairway average be? Work on that distance alone and you’ll find your scores coming down quickly. Just rethink your last round of golf and figure out what you would have shot if almost all your shots from 125 or less were inside of 35 feet or so?
And finally, these guys average getting up and down from inside 30 yards nearly one out of three times! All their strength advantage over you is neutralized if you’re only trying to hit the ball 30 yards or less, right? How does that stack up to your up-and-down success? Maybe a place to practice this spring, huh?

the soft conditions help stopping the ball on the greens a lot. looking forward to see how these guys play when it's dry, cement-like, and fast(ie, augusta, where even that shortish rough affects spin). and short shots out at pebble in june; the course will play dry for sure. i'm actually hoping the pros do end up getting it closer on average from the rough cause i think the whole rule is ridiculous to begin with, sticking it to the USGA.
Terry, its so evident... as you AND many others have been saying for a long time... SHORT GAME - SHORT GAME - SHORT GAME!! *promises to read the Scor book again* LOL!
Sounds to me like they have been practicing the full array of shots with more seriousness than years past.... Better golfing eh...
TeT, I have a hard time beleiving that overall they will be practicing more now than previously. There is so much money and prestige on the line, that anyone who is serious will, and always has practiced alot. I think Ed Word may be on the money. They have had quite a bit of rain with soft courses so far, lets see what happens when they hit the concrete hard courses. This will be interesting.
I hit the fairway with my drives about 50% of the time, Hmmm a bit of practice, the seniors tour, Hmmm, Oh, Oh, time to wake up. :)

aren't there still some approved clubs with the old grooves being played with due to lawsuits? what percentage of the pro's really changed their grooves?
Nearly all the pros had to change their irons and wedges to conform to the new rule. Some had made that change well into last year, but they all had to abandon the previously conforming grooves for play on the tour this year. The old Ping anomoly notwithstanding.
I wonder if they (the pros) have regressed to playing simpler shots. Instead of trying to throw the ball to the hole and making it stop, could they be simply playing for less spin and letting it role out? That's the higher percentage shot, at least in my mind, regardless of how much spin you generate.
i think a better stat to look at would be, what is the relationship between driving accuracy and place finished in the 4 tournaments this year versus last year. For example, what rank in driving accuracy (for that particular event) did the winner have this year versus last year? I think this would be a much better indicator of whether the new grooves are playing a role
