CHASKA, Minn. — Tiger Woods isn't backing down.

He thinks it was wrong for European Tour chief referee John Paramor to issue a warning for slow play to Woods and Padraig Harrington in the final round of the World Golf Championships-Bridgestone Invitational Sunday.

Woods held Paramor at least partly responsible for a four-shot swing on the 16th hole at Firestone Country Club, after the referee told Woods and Harrington they were being put on the clock.

Harrington, who had a one-stroke lead, rushed three shots, hit his fourth shot from behind the green into the water and walked off the green with a triple-bogey. Woods made a birdie and suddenly had a three-shot lead.

He went on to win his fifth title of the year and 70th of his career.

"We were the only two in contention to win the event," Woods said Tuesday at the 91st PGA Championship. "We were having a great battle. Unfortunately, I guess we had to finish by 6 o'clock. I guess that was that important."

Asked if he regretted "personalizing the issue" by criticizing Paramor Sunday, Woods said, "No, because he's the one who did it."

Harrington, the defending PGA champion, said he hadn't read Woods' comments but declined to blame Paramor for his collapse.

"I reacted poorly to the situation and that's my own fault," he said. "As regards to what (Woods) said, I think it's easier for him, having won the tournament, to take the moral high ground and say what he wants. Having lost the tournament, I'm going to take it on the chin and say it was my mistake."

Woods didn't deny the fact that he and Harrington were out of position and that slow play has long been a problem on the PGA Tour. But he thought common sense should have prevailed.

"I thought they would have used better judgment, considering we were the only ones that were probably going to win the golf tournament," he said.
