Dusting the field

Dustin Johnson, who won the rain-shortened AT&T National Pro-Am last week, shot a 5-under 66 Thursday and is tied for third.
"I don't know, golf, when you're playing well, you just kind of keep going," he said. "I've been working pretty hard on the game and it's feeling good right now."
Even though the final round was washed out last week, Johnson said he got a confidence boost from the victory.
"When you're real confident, even your bad shots are not that bad," he said. "They are still around the flag where you have to either look at birdie or get a good chance at par."
