The 22-year-old Northern Irishman has been working with longtime coach Michael Bannon on improving his swing setup.
“I still feel it’s going to take a couple more weeks to fully click in,” McIlroy said Wednesday. “But it’s definitely on the right track.”
McIlroy leaves for the United States on Monday to play in the Accenture Match Play Championship, which starts Wednesday. The Masters begins April 5.
McIlroy opened his season by finishing second in Abu Dhabi and fifth in Dubai last week, when he revealed he’d been working on a “few fundamentals” in his swing.
“Posture was one of the key things, and just a little bit of swing plane,” McIlroy said. “I was setting the club a little steep on the way back, so the club was getting a little bit across the line at the top.
“So Michael and I have been working on me getting more feel, and getting the club pointed a little more left at the top so it’s on the right plane. That’s basically it.”
He added: “I should be well and truly ready for Augusta.”
