Since then, he has become the Green Jacket nearly man, threatening to extend his wardrobe on the final day only to fall just short.
In his last 10 editions at Augusta, he boasts seven top-10 finishes and produced a stunning final-day surge to finish runner-up to Scottie Scheffler in 2022. But sandwiched either side of that are two missed cuts, last year's perhaps the more notable, McIlroy having begun the tournament as the standout favourite.
Looking at the numbers, it is Scheffler rather than McIlroy - and intriguingly they are paired together today-who is this week's man to beat.
In between winning in Dubai in January and finishing third in Texas last week, McIlroy's results of 66th, 24th, 21st, 21st and 19th are hardly indicators of a Masters champion-in-waiting.
And yet he has a growing belief an altered approach to the opening Major of the year could pay dividends. He is more golf-fit, having played more tournaments than he would usually at this time of the year. Plus, he is under the radar well, as much as one of the greatest to play the game can be.
Added to that, prior to Texas, he has sought out the expertise of swing coach Butch Harmon (right, this week), his offerings, according to the player, making him half-coach, half-psychologist.
