West Waterford's Seamus Power overcame a slow start to his week to make the cut in the Shriners Hospitals for Children Open in Las Vegas.
Two over after 12 holes of his first round, he dug deep to post a level par 71 then added a four under 67 in last night's suspended second round at TPC Summerlin to end the day tied for 48th, one shot inside the projected cut.
Starting at the 10th, Power rattled off six birdies and two bogeys in a four under par effort, single-putting 10 times in a 26-putt round.
However, Graeme McDowell looks set to miss the cut as he lies a shot outside the projected mark on two under par after a second successive 70.
Two under for the tournament through eight holes, the Portrush man made a double bogey seven at the ninth when he failed to escape from a greenside trap with his third, then overshot the green and took three more to get down.
He rallied with birdies at the 10th and 16th but looks unlikely to survive for the weekend.
Australian Rod Pampling added a 68 to his opening 60 to lead by one stroke on 14 under par from Brooks Koepka, who followed a 62 with a 67.
"The hole looked really big yesterday," said 47 year old Pampling, a two time PGA Tour winner.
"I started out today and I didn't think they'd cut them (the greens) early on. I changed ball markers, and I knew I was playing good, so I just kind of threw out a new vibe, and it started to work. I knew it wasn't bad, it's just like it happened, so just let it go. Corrected myself and played nice after that."
Koepka won the Waste Management Phoenix Open last year for his first Tour title and was 3-1 in the United States' Ryder Cup victory over Europe.
"The ball seems to be finding the hole once we get it on the green, so just get it on the green as quickly as possible," Koepka said.
