DUBLIN, Ohio – Tiger Woods said he had tension in his lower back area on Thursday morning during the first round of the memorial, a rare admission of discomfort attributed to the time before the first of his operations more than four years ago is.
While Woods has described his struggles in detail in recent years, he rarely did so while performing and was typically less than willing.
But Woods said he has difficulty disengaging when he played his first seven holes in 4 over at the Muirfield Village Golf Club before retiring in the first round of the Memorial Tournament to shoot par 72.
"I did not do very well today, the back was tight, and that's exactly what it is on some days." Woods said, "And I made some improvements in my momentum, my setup, and see there, I was able to make some good turns on my back and turned the whole thing over. & # 39; 3959002

 Woods, 42, played his last 11 holes in 4 under par, with five birdies, and shot 33 on Muirfields front after he started his round on the back and shot 39.
Under his early failures were missed by four straight fairways from the tee, a third shot in one m Water obstacle at the Par-5 11th and a discount on the Par-5 15.
Woods insisted that his worries were nothing to worry about, that this was normal after a spinal fusion operation more than a year ago  "It just happens," he said. "I did not feel so good and just had to make some adjustments, and I was able to do it spontaneously, which was nice."
Woods, who played long, detailed practice sessions in Shinnecock Hills – said – The US Open site – on Monday and Tuesday before the pro-am at Memorial on Wednesday, said the additional golf was not the culprit.
"No, I only have such days," Woods said. "It's going to age and it's surgeries." It's what it is, I just have to make the adjustments, I'm able to make them now. "At the beginning of the year, I could not do them because I did not really know what to do is still to be done. "
Woods said he might feel when he woke up that he could be there for a difficult day, and his back hardening did not get any better during his warm-up phase His back finally loosened Woods said: "That did not do it."
"I have days like these," he said. "My back is overgrown. I'll have days when it's tight. Unfortunately today was one of those days and that's fine. I have no pain, thank God. It's just tight. So, no big deal.
Unlike what it did to his score, five birdies should normally be below average numbers, but Woods sat back far, playing the par-5 over his first 9 holes in 3 over par.  Rain moderated the course significantly and provided good scoring conditions. Abraham Ancer and Joaquin Niemann led the early wave at 65.
Woods landed on 9 of 14 fairways and 12 of 18 greens and needed 29 putts – including a good par-rave on the ninth, its last hole.
A five-time winner of the Memorial, Woods did not shoot in the 60s at Muirfield Village since the last round of his 2012 victory, and has since completed nine laps at 70 or higher, Among them was a third round 79 in 2013 and a third round 85 in 2015.
"The golf course was soft, the ball flies," Woods said. "The fairways are playing so big, because they are so soft. You do not have to worry about them phasing out and you can be very aggressive on the tees. But you miss it in this rough, you will be punished. "
