I just sat through Phil Mickelson's tense news conference where he really let the USGA have it. Because my lunch takes priority, here's what you need to read before we get into his comments which were both incredibly valid and oddly inconsistent.

The story is by E. Michael Johnson and Mike Stachura from last August. It details a late-in-the-game clarification by the USGA and Dick Rugge.

"Manufacturers are reminded of the intent of the new groove regulations as stated in the February 27, 2007 Notice to Manufacturers: The objective of this change is to limit the effectiveness of grooves on shots from the rough to the effect of a traditional V-groove design."

In other words, it doesn't matter if your grooves conform to the written specs, if you create something that makes the ball spin out of the rough more than we like, it's non-conforming.

"We are trying to make it crystal clear that the rule was intended to return the grooves' effectiveness on shots from the rough to that of traditional V-grooves," says Dick Rugge, senior technical director of the USGA. "That's an important factor. It was our clear intent. We developed a number of helpful provisions in the rule for manufacturers. These provisions are not meant to be ways to get around the intent of the rule. If we chose to look the other way in these areas, we wouldn't be upholding our responsibility."

But while Rugge sees it as upholding the USGA's responsibility, some manufacturers view it as something entirely else.

"It's like moving the goal line just as someone is about to score a touchdown," says Michele Szynal, spokeswoman for Callaway Golf, who added the company had products ready to show its tour players starting in August so they could be ready for their January 2010 deadline. "It's our job to maximize golf club performance within the written rules. That's pretty tough to do when the rules change monthly."

And this from Benoit Vincent of Taylor Made:

"It is not a rule, it is a process to control the future," says Benoit Vincent, chief technical officer for TaylorMade. "It's like the adjustability rule. The USGA said submit your adjustability and we will tell you if it's OK. I said 'That's not a rule. That's submit your stuff and if we see something we don't like we will rule even further.' If it's outside what they have studied and what they know, then they will rule against it. So what they are doing here with grooves is typical of what they do."

Okay, that's a table setting, now I'm off to lunch to chew on the Finchem and Mickelson prss conferences. Appetizing!
