Club professional Michael Block’s fairytale week at the US PGA Championship continued with a hole-in-one in Sunday’s final round at Oak Hill.

Playing alongside four-time major winner Rory McIlroy, Block’s tee shot on the par-three 15th slammed straight into the hole for an eagle to get him back to level par for the day.

The 46-year-old, who is the head professional at Arroyo Trabuco Golf Club in California, struggled to believe what had just happened, saying: “No, no. No way. Rory did it go in?”

After retrieving his ball Block realised that it had damaged the hole and that there would be a slight delay while that was repaired.

“I will cause that delay every time, I don’t care,” he told his caddie.

Justin Rose admitted his second round of 70 was not quite what it seemed as he remained in contention to double his major tally in the 105th US PGA Championship.

Rose shot level par on Friday to post a halfway total of one under par, despite hitting only two fairways in regulation at a fiendishly difficult Oak Hill.

“Smoke and mirrors I guess,” the former Olympic champion said with a smile when asked how he had pulled it off.

“I had a few fair lies in the rough, to be honest. When I did catch a bad lie I took my medicine and pitched out and tried to avoid the big number. I felt like making a bogey or two around here is no big deal.

“The fact that I made 10 birdies [in two rounds] is remarkable considering how I’ve put the ball in play off the tee.

“Iron play I felt was pretty good and obviously I have made some really nice mid-range putts. There’s definitely been some highlights in the game the last couple of days.

“Lots to look forward to and to have kind of going into the weekend, but kind of nice to know that I can maybe try and tighten a few things up as well.”

Rose won the 2013 US Open at Merion with a total of one over par and is relishing another tough challenge over the weekend.

“I think historically I’ve won typically on harder golf courses than not, so I think it fits my profile from that point of view,” he added.

“This is right up there. This feels a little bit of a hybrid kind of PGA/US Open this week. I’m looking forward to the test, I think.

“I thought four under par would be the winning score before the tournament started. It’s very hard to hit the ball in the fairway right now. The fairways are so firm that that’s what’s kind of making them so hard to hit.”
