Teenage star Rory McIlroy struggled to match his first-round heroics but still secured the silver medal for best amateur at Carnoustie on Friday.
McIlroy double-bogeyed the 9th after this drop
The 18-year-old, who had no bogeys in a stunning three-under 68 on day one, could only manage a second-round 76.
The round included a double bogey, five bogeys and two birdies, and leaves him on two over par, well inside the cut.
His compatriot Graeme McDowell carded a 73 to end eight over and Darren Clarke a 76 for six over, both missed the cut.
With no other amateurs surviving for the weekend, McIlroy followed in the footsteps of the likes of Jose Maria Olazabal, Tiger Woods and Justin Rose in winning the silver medal and became the first Irish amteur to make the cut for 40 years.
Despite his second-round wobbles, McIlroy was delighted to have made the cut and is looking forward to the final two days.
I just wanted to go out there and try my best, play golf and enjoy it
"To play at the weekend is amazing, it's the biggest stage in golf so it's really nice to perform," he said. "I really enjoyed the last couple of days and I just hope to go out tomorrow and keep playing good golf.
"I was happy enough with two over. It is not that bad, 76 does not reflect how I hit it.
"I just wanted to go out there and try my best, play golf and enjoy it, and that is what I did. I didn't get upset with bad shots.
"The course is getting tougher and the wind is picking up, and I think I'll work on my putting tonight because that's what let me down at times."
Dubliners Padraig Harrington and Paul McGinley both lie on level par going into the final two rounds.
Harrington carded a second round 73 early on Friday and McGinley, who was among the later starters, fired a four-over 75.
