He used his playing partners club? What the heck... how dumb can you be?
Not sure about you guys, but I know my clubs from someone else's... OK, so I am a lefty and the obvious should help... but that's a wholly different joke.
Seriously, I believe this one is the players responsibility. Players are always tweaking to make sure their clubs are exactly to their specks. He surely should notice a grip variance or something. This one is even more bizzare that Woosnam's gaffe with the driver.
