Zach Johnson may be getting the hang of this fame thing.

After winning the Masters in April for his first major championship, the 31-year-old native of Iowa City, Iowa, discovered the schedule got busier — a lot busier.

"The difficulty lies in the fact we're just inundated with stuff. Some of it is chaos, and you've got to control that, but a lot of it is just stuff, whether it's requests or mail or signing," he said.

"I'm on the phone with my agent at least once or twice a day, trying to figure out a game plan. I've gotten very busy."

And very recognized, too.

"That happens more often than it did, prior," he said.

"I'd say once the Ryder Cup hit there, too, was a change as well. Augusta certainly did. Any time you do something like that, and there's sort of a spectacle. I mean, things are going to change a little bit as far as notoriety and what not."

Still, Johnson has hardly let the fame go to his head.

He's still the Midwestern boy with the great work ethic.

He wants to win — every week.

"That's what I'm supposed to do," he said. "I don't expect to play well every week or every day, but I mean, yeah, I expect a lot out of myself."

It wouldn't hurt, he said with a laugh, to take home part of the Target World Challenge's $5,750,000 purse.

"I didn't make any cheese at the Skins Game," he said with a grin. "I've got to make some cheese this week, baby."

Mitchell Report reaction: Tiger Woods said he was saddened by the baseball players named in the Mitchell report, which was released Thursday.

"That's not good," he said. "It's a shame that, and I haven't seen the report, that athletes have tested positive. I think kids look up to athletes, and we don't want the kids to be led down that path."

He also reiterated his support for drug testing in golf.

"I think it's a good thing," he said. "I know our sport is clean, but obviously the perception is athletes in all sports are pushing the envelope. In our sport, I don't believe we do that. It would be nice to prove it to the world."

Pro-ams: The pro tandems of Mark O'Meara-Jim Furyk and Tiger Woods-Brad Faxon led their teams to a first-place tie in the tournament's Pro-Am, held Tuesday and Wednesday.

O'Meara-Furyk led a six-man grouping that finished at 103, or 41 under. The amateurs were J.P. McManus, Noreen McManus, Cian Foley and Nick Diaco.

Woods-Faxon also finished at 103. The team's amateurs included Rich Varda, Scott Nygaard, Drew Gissinger and William Perkins.
