Casey keeps fatigue at bay

The Englishman has had a busy schedule in the lead-up to the event regarded as the most prestigious outside the four majors, playing events in Japan and China and then moving home last week.

The world number 13 said: "I feel a little tired from a lot of travelling but the form is good."

Casey was the only uninjured player among the world's top 30 who did not play in last week's Wachovia Championship in Charlotte, North Carolina.

He explained: "I didn't want the Players to be my fourth week in a row.

"It has been a balancing act so far this year, with all the travel and trying to be fresh for the big events, but I've had enough rest time this week.

"It's fun to play in China and Japan, but the important thing is I have to be ready for the big stuff, the majors and the Players."

Casey did not play very well at the Chunichi Crowns in Japan, where he tied for 12th against a weak field, but it is worth recalling he was in the hunt at the Masters until a disastrous triple bogey at the 15th hole of the third round.

"I played some really nice golf at Augusta but scattered it with too many mistakes," he added.

"I've made too many mistakes on the course this year and I've got to eliminate that, because I feel fine with my game."
