Paul Dunne is five shots off the leaders at the Farmers Insurance Open at Torrey Pines at the halfway stage, with Shane Lowry two further back..
The Greystones golfer shot a one under second round to keep himself in contention.
American Gary Woodland and KJ Choi of South Korea lead on nine under, with Dunne amongst a group of players on four under.
Three straight late bogeys from multiple major winner Phil Mickelson saw him miss the cut.
But at least Mickelson was in good company as defending champion and world number two Jason Day also failed to make it to the weekend's play in California.
Woodland hit a five under par 67 on the South Course and Choi equalled that score on the North Course to lead by one stroke from home player Dustin Johnson.
Dunne hit three bogies and a birdie through the fist 16 holes and was flirting with elimination.
But he finished the last two holes birdie, eagle to pick up three shots and get back into the mix.
Woodland had eight birdies and three bogeys and Choi seven birdies and two bogeys.
"I drove the ball in the middle of the fairway. Good things are happening when I drive the ball on the fairway,” said Woodland.
"I'm confident with the way it is. I'm confident with this golf course. I've played well here the last couple of year so I'm excited about the weekend."
A three-way tie for fourth on seven under par features Scotland's Martin Laird and Americans Scott Brown and Billy Horschel.
Dunne is tied for 18th on four under, two shots ahead of Shane Lowry and England's Greg Owen.
With the cut falling at one under, Mickelson's poor late run saw him finish on one over with Day a shot further back.
