Rory McIlroy is confident he has "straightened out" his waywardness ahead of next week's US PGA Championship.
The Masters champion admitted a problem hitting it left, which afflicted him on the Saturday of his title defence at Augusta, caused him problems in the Truist Championship, which was eventually won by Kristoffer Reitan.
A final-round 67, which included six birdies and two bogeys, saw McIlroy finish five under and well off the pace, the winner 10 shots better, but he hopes a range session on Saturday has cured his mis-hits.
"I started to hit it left yesterday with everything. That’s sort of my bad habit at the minute and I just have to be aware of it," said the world number two, who has also been struggling with a blister which he insists will not affect him next week.
"I was much more aware of it and did a better job of managing it today. I spent a good bit of time on the range last night just trying to straighten it out.
"I think the range session last night was good. I figured out a couple of things, so straightened that out.
"I’m going to go home tonight, which will be nice to spend a night in my own bed and practice at home tomorrow to try to just sort of continue that feel and bring that up to Philadelphia for the rest of the week."
McIlroy travelled to Aronimink for a day last week to get an advanced look at the course.
"It was nice to get an early look at it," he added.
"It just means that the week of the tournament you’re not under pressure to play a lot of holes.
"Historically the practice rounds at the PGA can be excruciatingly long, so it’s probably going to just be nine holes Tuesday, nine holes Wednesday."
Norway's Reitan took the Truist title, shooting a final-round 69 for an overall total of 15-under par, good enough for a two-shot win over Americna Rickie Fowler and Denmark's Nicolai Højgaard.
