Paul Casey didn't feel the pressure. Even as he made his charge up the Masters Tournament leaderboard Saturday, he stayed relaxed.

The English golfer birdied six holes and finished the third round with 69. After the second round, Casey had been tied for sixth place, but his front-nine 32 Saturday helped him to move to fourth place with a three-day total of 7-under-par 209.

"You can't be overconfident on a golf course such as this," said Casey, who posted a 69 for the second straight day. "You have to roll with the punches, and that's what I did."

Casey said he and his caddie, Craig Connolly try to keep the atmosphere fun.

"He's a friend before he's a caddie," Casey said. "We try to enjoy ourselves out there. It's tough to try and enjoy yourself on a tough, tough golf course.

"I give every shot maximum effort and focus. As soon as the putt is gone and it's rolling, then it's over. It's as simple as that."

Connolly declined to comment until the tournament ends today.

When Casey hits a bad shot, he tries not to get too flustered. On Saturday, it happened on the 11th, 15th and 17th holes where he made bogeys.

"I like to think that if I do drop a shot, then I bounce back very, very well," he said.

The third round didn't start the way he wanted, hitting his tee shot into the fairway bunker on the first hole. He escaped with a solid shot but missed his birdie putt.

He got rolling after a birdie on the second hole. Four of his six birdies came on the front nine.

"It snowballed from there," he said. "I suddenly didn't get wrapped up in the score and where I was under par relative to the day and where I was on the leaderboard."

Casey relied on his recent practice with a well-known golf instructor.

"I spent a lot of time with Peter Kostis, hitting different shots that I think are required for this golf course -- and a lot of time on fitness and a lot of time on the mental side of things," he said. "I'm very, very happy with the state of my game. I haven't played good golf coming into this tournament. So far this year, it's been a little lackluster."

Entering today's final round, Casey is four shots behind the leader, Trevor Immelman. The two golfers saw each other every night last week while eating dinner at the same house, but Casey is not concerned with Immelman's play.

"I'm very excited about (today)," he said. "I can't wait to get it started. I'm going to worry about my own game and not worry about what anybody else is doing and continue to play good golf."
