Rory McIlroy returned to form in spectacular style with an eight under par second round at the Players Championship, which included a record equalling 29 on the back nine, yet admitted afterwards he still felt frustrated and disappointed.
Following a level par 72 in the opening round at Sawgrass, Holywood ace McIlroy roared back into contention at the tournament, known as the 'fifth major', with a 64 yesterday.
Starting his round on the 10th hole he hit four birdies in a row, another at 15 and an eagle on 16 on his way to that 29, which equalled Irishman Shane Lowry's record the day before.
Another two birdies followed, only for him to hit a bogey six on his final hole, the ninth, meaning he finished at eight under.
He still trailed the leaders, but will fancy his chances over the weekend.
Even so when asked for his post round feelings, McIlroy, who has won four majors, said: "Disappointment. I'm frustrated. It should have been a couple better.
"I was going well and it would have been nice to make a four on the last, but 64 is still a great score. I hit a lot of quality shots. I feel like my game has been under control the last four rounds so hopefully I can continue like that over the weekend."
