The swing changes that Rickie Fowler made in December are starting to pay off.

Fowler, known for the bright colors he wears and the flat bill of his cap, shot a 5-under 67 in the third round of the Masters on Saturday. He is 3 under for the tournament and in position to win his first major.

Fowler began working with Butch Harmon to improve his takeaway.

“Our main goal is to be here right now ready to contend and have a chance to win the Masters,” he said. “So … so far, so good.”

Fowler has never finished higher than 27th in three appearances at the Masters. But he said he is ready. In addition to the experience he has gained playing Augusta National, he has sought advice from past champ Phil Mickelson. The two played a practice round on Tuesday that led to Mickelson raving about how Fowler was playing. He is also good friends with Bubba Watson, the 2012 champ.

“I really comfortable on this golf course now,” he said. “After the first three tournaments and practice rounds here, I feel like I’m able to go around this course with a little bit more feel instead of trying to calculate my way around at times with slopes and how much it plays up or down. Definitely getting more into the feel, which is how I like to play the game.”
