Groove Measuring Methodology And Timing

One of the main PGA Tour/manufacturer gripes with the USGA/R&A groove rule change--now endangered for 2010 implementation--deals with the assertion that the USGA fell behind in getting manufacturers an appropriate measuring tool to determine if irons are conforming.

I know this isn't the sexiest topic, but it is important to understand how this process played out so that should the PGA Tour delay the groove condition of competition due to manufacturer concerns, we at least know how much time they had to prepare. So I asked Dick Rugge of the USGA for his response to the claim of not enough time:

1. The August 5, 2008 Notice to Manufacturers regarding the new groove rule implementation included a detailed explanation of how grooves would be measured.

2. The August 5, 2008 Notice to Manufactures also included the following information: “Measurement of grooves for cross sectional area and groove edge radius can be made with the same tracing equipment that the USGA has used for a number of years. The USGA may also make use of additional measuring equipment for this purpose in the future. A field test to enable groove measurements on-site has been developed. The protocol for this field test will be published in the near future.”

3. The ContourReader (that’s the “tracing equipment that the USGA has used for a number of years”) groove measurement procedure has been made available to those requesting it.

4. Both the USGA and the R&A have purchased a device from the Alicona company that utilizes a very sophisticated microscope to measure grooves. This has been considered our “gold standard” measurement device. That company has offered their equipment for sale to club manufacturers. The cost is high, so there will likely be a limited number of these in use.

5 We have developed a field test device which uses a flat-bed scanner to accurately record the groove cross-sectional shape. This device has been reviewed by PGA Tour rules official John Mutch, who is pleased with its function. This device will soon be made available to the Tours, and to other appropriate organizations, including manufacturers.

"Unfortunately, the only uncertainty in the game right now lies with who's in charge of it."

GolfDigest.com blogging duo Bethpage and Garden City kick around the power struggle over a groove rule condition of competition and ultimately determine that the USGA has handed over power to the PGA Tour and that the uncertainty over 2010 implementation has the USGA acting as a follower instead of a leader.

I can tell you this, though: The rule as currently written will not be a hardship for the playing of the game by average golfers in any meaningful way, shape or form. Not now, not in 2014, not in 2024, not ever. The rule as currently written does present the possibility for uncertainty in the minds of the best players in the game, however. Uncertainty (or as most of us know it, outright fear), I think, makes for a better game at the elite level.

Unfortunately, the only uncertainty in the game right now lies with who's in charge of it.

"If there are enough rumblings it wouldn't be out of the realm of possibility that we could not adopt the rule."

E. Michael Johnson and Mike Stachura's news story about the PGA Tour inching closer to a delay of the groove rule change includes some revealing quotes.

"Last night there was a conference call and we decided that it was too heated of an issue to decide on a conference call so we're going to wait until next week's board meeting to make a decision about it," said Stewart Cink, a member of the tour's policy board. "I would expect by Tuesday there will be some kind of an answer on it."

Then this from former policy board member Joe Ogilvie:

"They botched it and because they botched it, it won't be implemented in 2010," said Ogilvie. "I'd say there is a 90 percent chance it is not going to happen. I think they are going to have to [change the date]. I don't see it being adopted earlier than 2011."

So we are left with all sorts of questions as to why this has become an issue at the last minute.

The manufacturers have had some idea this was coming since August, 2006 and specs since August of 2008. Based on Twitter and interviews, players who have taken the initiative have had several months now to experiment with the new grooves.

The PGA Tour and Commissioner Finchem have been very consistent in stating that they support the USGA and R&A (here, here and here make a nice starting point for background on the tour's position and statements that certainly won't mesh with backing out of the 2010 date). But we also know from last week's USGA press conference that they are placing themselves at the mercy of the tour.

The "botching" referred to by Ogilvie seems to be with the confusing dates for implementation (2010, 2011, 2014, depending on who you are). I find it humorous that the PGA Tour, which hasn't done a whole lot of worrying about the every day game, is suddenly worried about the plight of the average golfer?

We know from Ian Poulter that this timing confusion is an issue to Acushnet family members, as is the dramatic difference in shotmaking ability. And we know from Stewart Cink that there will be a big difference, largely because players will have to move to a softer, spinning ball.

So if players convince the tour they won't be ready, they'll be branded pathetic, soft and spoiled.

If this is a manufacturing issue, as suggested, it would seem odd that these big, powerful, hi-tech manufacturers are unable to accommodate a rule change that will essentially impact certain sets of irons and their wedge lines. Manufacturers will take a hit to their tech savvy brands.

Unless we are not talking about multiple manufacturers here, but instead, just one company that doesn't feel it can retool its assembly line or perhaps doesn't feel it has a soft enough ball in the pipeline for circa 2010. Then we might see other manufacturers point that out and it could get ugly.

I'm just going to sit back and watch. Oh, and just for the last time, I swear, ask, wouldn't it have been so much easier to just change the ball?

"There's rumors floating around here this week that it may not even come into play."

From Greg Norman's chat with the working press Wednesday prior to the Senior PGA:

Q. When you were younger in your 20s and 30s you were obviously a great ball-striker, but always considered one of the best drivers of the golf ball. That was in the year of the persimmon heads. Has it changed a lot now? Do you think there's more guys who hit 70 percent plus in fairways hit because of equipment or back in the day that was a heck of a lot harder figure to reach?

GREG NORMAN: I think it's easier to hit the golf ball straighter now days. And the ball goes longer. No question. Is that -- that is technology. No question about it.

I think a great barometer, just to get off your question a little bit is, a great barometer is when the V grooves come into play next year. And I hope it does. There's rumors floating around here this week that it may not even come into play. But if the V grooves do come back into play, that will be a great barometer to see how good these players are with their touch and their feel and their imagination. And understanding that that ball, it looks like it's going to leap 40 yards extra off the club face, how do you play that?

That's going to be great to watch on television. Because that's, to me, is the art of understanding the game of golf. And understanding the spin of the golf ball. Not just a pure given fact if you hit it in the rough and I did it a couple times today on these firm greens, I'm in the rough, I know it's going to spin, I'm just going to open that club face up a little bit more and the ball comes down like an old dog lying by a fireplace. It just drops on the green.

Now that's not going to happen next year. So those are the type of things that actually help the better players distance themself from the average players. And I think that's why in my generation you saw such great shot makers out there, Trevino and like I said, Seve in a lot of ways, he hit phenomenal shots.

"There's going to be a break-in period"

E. Michael Johnson offers a short primer on the groove rule change and notes that many players are opting to wait until later in they year to even practice with them, something that has surprised me in conversations about the U-groove change. And apparently Jim Furyk agrees.

"I think it's a good idea in kind of getting players involved and saying, hey, don't wait till the end of year," said Jim Furyk. "This is something you want to get a hold of early on."

To that end, Furyk received some wedges with the conforming groove to test just prior to the WGC-CA Championship at Doral. Those who opt to wait, he said, might be in for a bit of a surprise.

"There's going to be a break-in period," said Furyk. "Some people will start January 1 with no issues and other guys, they are going to need some time to get used to it. But eventually, give it six months or whatever, and everyone is going to be on the same page."
