THOUSAND OAKS, Calif. -- Keegan Bradley misses being able to show up at a tournament, do his thing, and go home. But when you win -- and win a major as Bradley did earlier this year at the PGA Championship -- and are one of the best young players in the game, something has to give. For Bradley, 25, that meant time.

“The toughest adjustment for me…I pride myself on being very well prepared,” Bradley said Tuesday. ”There’s a lot more I have to do at a tournament now.”

At the start of the year, and even just prior to winning the PGA, Bradley couldn’t even have imagined playing in this week’s Chevron World Challenge. Now he must battle not only a slew of off-course demands, but on-course ones as well.

For example, Bradley has played in the PGA Grand Slam of Golf, the World Golf Championships-HSBC Champions in China since the end of the PGA TOUR Playoffs for the FedExCup, and he’s in the field this week and next for the Franklin Templeton Shootout.

In other words, saying no can be difficult.

“There are so many events you can play in the offseason, it’s not really an offseason anymore,” Bradley said. “It’s just another tour basically.”

For now, though, Bradley’s soaking it all in and looking forward to 2012.

“I know what I’m doing [this time around] and am able pick my schedule,” Bradley said. “I’m so excited to get back out there … and I’m not freaking out about my TOUR card.”

Bradley won’t have to wait long. He opens his year at the season-opening Hyundai Tournament of Champions, followed by the Sony Open in Hawaii before the West Coast Swing.

As expected, the 18-player field for next week's Chevron World Challenge was released. Here is a quick look at the players in the field for this year:

Keegan Bradley: First appearance. Was T16 at World Golf Championships-HSBC Champions.
