The Northern Irishman won four majors between 2011 and 2014 – twice at the PGA Championship, plus the Open Championship and US Open – but was never in contention as he looked to become only the sixth man to complete the career grand slam.
His attentions will now turn to the US PGA Championship at Valhalla in mid-May, with the US Open at Pinehurst to follow in June and then the Open Championship at Royal Troon in July.
“I think it’s just a matter of me getting my game in a bit better shape going towards the rest of the season,” reflected McIlroy.
“I need to take a little time and reflect on this week and what I did well and didn’t do so well and try to make a plan for the next few months, especially from here to the end of July, going through major season.
“They’re obviously going to come thick and fast here so I’ll hopefully get myself in a bit better form for those last three.”
