It hasn't been a good couple weeks for Sergio Garcia since his near-miss at the British Open.

And it got worse Saturday when he was disqualified from the PGA Championship for signing an incorrect scorecard.

Playing this morning after barely making the cut, Garcia bogeyed the par-4 No. 17 hole, but playing partner Boo Weekley - playing partners keep one another's scorecards - mistakenly wrote down a "4."

In the scoring tent after the round ended, Garcia failed to notice the error and signed for the incorrect score. Once he left the scorer's tent, that's an automatic DQ.

"It's my fault for putting the wrong score in, but it's his fault for not checking," Weekley said.

Weekley's right, of course: Each player is responsible for making sure his scorecard is correct, even though his playing partner was the one writing down the scores.

And remember, Weekley is the guy who earlier this year was penalized when he gallantly tried to help a playing partner avoid a penalty. He removed the flagstick after his fellow-competitor's caddie had forgotten to do so, because he didn't want the playing partner to be penalized. Oops, sorry Boo, that's a penalty on you!

So if Boo more or less shrugs and says, "Yeah, I screwed up, but he screwed up worse, and them's the breaks," well, I guess I understand.

At any rate, as I said, Boo is right: Mistakes happen, and it's each golfer's responsibility to make sure his scorecard is free from those mistakes before signing that card. If they don't, DQ.

Better luck next year, Sergio.
