Rory McIlroy admits his post-lockdown game has been a mixture of the good, the bad and the ugly as he struggles to keep his concentration on the new-look PGA Tour.

After scrambling to a level par 72 alongside a struggling Tiger Woods and Brooks Koepka at Muirfield Village to go into the weekend seven shots behind clubhouse leaders Ryan Palmer and Tony Finau in the Memorial Tournament, he insists that he must "focus on focussing" to get back to top form as the first major of the season approaches.

The Holywood star admits he's struggled to concentrate since returning to action a month ago and must now take steps to avoid the "bad errors and mistakes" that have left him without a top-10 finish since his return to the fairways.

"Honestly, that's been the story of my golf game since we came back," said McIlroy, who could lose his world No 1 crown to Jon Rahm tomorrow.

"There has been quite a bit of good in there, some bad and some bad errors and mistakes."

As Woods struggled with his back and was forced to finish birdie-birdie-par for a 76 to make the cut on the three-over-par mark alongside Koepka on three-over, McIlroy was left to reflect on a rollercoaster round.

Starting on the back nine, he was three-over after poor drives saw him start bogey, double-bogey. And while he made three birdies and a magnificent eagle three after that, he also had another three bogeys on his card, including his final hole.

"I didn't get off to the greatest of starts, three-over through two holes, but I felt like I battled back well to shoot what I did," he said.

"It would have been nice to finish a couple better if I had have taken advantage of that par-5 at the end, and the three-putt on [the last] sort of leaves a bit of a bitter taste, but I came back well, and that's all you can ask for."

With no fans lining the fairways, concentration is a problem for the Co Down man and not even a marquee group with major winners Woods and Koepka could get him zoned in.

"I alluded to that at the start of the week," he told Sky Sports. "I felt the first three events that I played... it was a good learning experience for me, as in what it is going to be like for the next few months anyway.

"You have to focus on focussing, if that makes sense. You just have to concentrate so hard because it is easy to lose focus out there. Playing with Brooks and Tiger, it is a marquee group, but it just doesn't feet the same. I'd say Tiger probably got his first sense of that this week.

"That's half the battle out there, just keeping your focus and I felt like I did it a little bit better over the past two days than the first few weeks and it's just something I am going to have to continue to work on."

There were still moments of brilliance, such as the sky-high, 260-yard five wood to nine feet that set up a spectacular eagle at the fifth that got his round back to level for the day but failed to raise a cheer.

But when it was pointed out to him that he hit that five wood closer than any wedge shot he played all day, he said: "I think I could bounce that back and say I'm No. 1 player on TOUR from 125 to 150 this year, so if you actually dig into the stats I'm actually hitting those shots pretty well.

"But today was just one of those days where I didn't hit good enough wedges."

As for Woods, the Masters champion struggled on the greens and with his body.

“Well, I don't have the same type of stamina as I used to have, that's four sure, when I was training hard and running and all that stuff,” he said. “Granted, I'm a lot older now, so things change, they evolve. Yeah, so it is what it is. Energy, you try to suck it up as best you can and get through it.”

He went on: “Aging is not fun. Early on in my career, I thought it was fantastic because I was getting better and better and better, and now I'm just trying to hold on.”

"Well, not very good. I three-putted two holes early, and whatever kind of momentum I was going to create, I stifled that early and fought it the rest of the day," Woods said "I wasn't quite moving as well as I'd like and couldn't quite turn back and couldn't quite clear. It was a bit of a struggle.

"It started this morning during the warmup. It wasn't quite as good as I'd like, and it is what it is."

While Woods made the three-over cut on the mark, Shane Lowry and Graeme McDowell missed out.

Lowry was outside the top 100 for putting, taking 33 putts as he bogeyed two of his last four holes and added a 75 to an opening 73 to finish outside the projected cut line on four-over.

McDowell struggled from the tee and followed Thursday's 79 with a 76 to end the week on 11-over. As for the leaders, Palmer shot a 68 and big-hitting Finau a 69 to lead by a shot on nine-under from Rahm, who posted a 67.

The afternoon brought disaster for Bryson DeChambeau, who made a quintuple bogey 10 at the par-five 15th and shot 76 to miss the cut by two strokes.

He was level par for his second round after mixing five birdies with five bogeys before making a series of poor decisions.

After pulling his drive into water he dropped in thick rough and instead of chipping out, opted to hit a draw with a fairway wood and hit two in row out of bounds right.

His third attempt—a provisional—bounded down a cart path and stopped just short of water. He found what was his fifth shot against metal boundary fence and argued it wasn’t out of bounds.

He refused to accept the referee’s decision — “I don’t believe it” — and asked for a second opinion. Another referee arrived and gave the same ruling.

DeChambeau played his eighth onto the green and two-putted for his ten.
