Back-to-back closing birdies has left Australian Greg Chalmers ready for a weekend charge at the PGA's Puerto Rico Open in Rio Grande.
The 47-year-old could have been forgiven for being a bit subdued following his opening-round heroics on Thursday when he had a hole-in-one for the second time in his career at the Grand Reserve Country Club.
But his impressive four-under 68 in Friday's second round under tough conditions leaves the West Australian hot in pursuit of leader Brandon Wu, who birdied four of his last seven holes for his one-stroke lead.
Chalmers birdied his starting hole on the 10th but then had bogey on the 15th to turn at even par. He then birdied the second, fifth, eighth and ninth holes before making his way to the clubhouse.
"I kind of struggled on the front nine," said Chalmers. "The wind was really blowing and I didn't have the greatest control and my short game really held me in good stead.
"And then I hung in there and started to see some better swings and better shots going into the back nine.
"There was a couple of par-fives there that we can reach and I picked both of those up. And then birdied eight and nine is a lovely way to finish."
Compatriot Cameron Percy is also in contention, his 69 leaving him tied fifth just two behind Chalmers at eight under for the tournament.
The Victorian mixed birdies at the 5th, 6th, 9th, 11th and 18th with bogeys on 6 and 13.
The 24-year-old Wu is playing in just his seventh professional PGA Tour event and this is the first time he has led a tournament.
First-round leader Tommy Gainey tumbled down the leaderboard with a 76, after his brilliant 65 on Thursday.
Gainey double-bogeyed the seventh and had four other bogeys with just two birdies on the day. He is in 38th place, eight shots off the lead.
