The four-time major winner has dropped from the top of the rankings to 10th, with putting at the heart of the 28-year-old’s recent struggles.
“At Augusta, you don’t need to putt great, you need to not waste any shots, no three putts, hole everything inside five feet,” McIlroy told BBC Sports NI.
“I feel good about Augusta, I know the golf course so well.”
Without a victory since September 2016, McIlroy had an encouraging start to the year as he earned top-three finishes in Abu Dhabi and Dubai but since then a share of 20th place at the Genesis Open has been his best performance in three PGA Tour events.
The Northern Irishman has been spending time with his putting coach Phil Kenyon in an attempt to improve what has often been the weakest part of his game.
The greens at Augusta are traditionally the most difficult of the year, but McIlroy thinks his putting game can master them.
You needn’t gap each 15 footer that you simply take a look at, you might want to be environmentally friendly, simply to not be wasteful,” he added.
“Velocity is import and lag placing, they’re large keys and I really feel like I’ve begun to get the lot higher at that, particularly there as a result of there’s a number of break and a number of completely different slopes however I feel I’ve it discovered.”
McIlroy’s 17 months and not using a event win is the longest barren spell in his skilled profession.
Nevertheless, if he can don the well-known inexperienced jacket he’ll turn out to be simply the sixth golfer in historical past to clinch a Grand Slam of all 4 majors.
McIlroy says he is approaching April’s occasion with confidence though admitting that the more durable he tries, the more durable it will get.
“I really feel like if I simply play my recreation it’ll all occur someday quickly hopefully – any week I tee it may very well be the week,” he stated.
“Successful is necessary and that is how I will likely be judged, however proper now it is in regards to the journey and getting again there. I am not that distant.
“Since I received the Open in 2014, the Masters is the most important occasion of the yr.
“This will likely be my fourth go at it (attaining the Grand Slam), I’ve had three top-10s within the final three years and I performed nicely, however simply not performed nicely sufficient.
