CENTRAL Victorian golfers Kris Mueck and Andrew Martin endured torrid second rounds at the WA PGA Championships on Friday.
Mueck failed to capitalise on his good start, while Martin tumbled down the leaderboard.
Martin was on track to miss the cut, but birdied the par-five 18th to scrape into the weekend's action.
He carded a three-over 75, one shot better than Mueck, at Kalgoorlie.
Mueck's opening day four-under par 68 had catapulted him to equal second, but he finished day two in atie for 26th.
The Axedale golfer had started brightly.
He birdied his second hole - the 11th - but a double-bogey on the 15th sparked a bad run.
Mueck bogeyed four of his remaining holes, with one birdie.
He remains in sight of the top-10, but is well back from leader Jack Wilson who is nine under par.
Meanwhile, Martin started slowly and couldn't recover in his second round.
The Neangar Park golfer teed-off in in range of the top players after carding a first round par 72.
However, he quickly spiralled into a dogfight to make the weekend's action.
A triple-bogey at the par-five second hole was a disastrous start.
Martin pulled one shot back on the fourth, but three bogeys in the next four holes were costly.
The former Australian Amateur champion hit better form on the back nine and birdied the 14th and then the 18th in a clutch hole.
He is tied for 47th entering the weekend.
Victorian PGA trainee Jack Wilson followed his opening round five-under 67 with another polished display in the second round.
The 22-year-old carded four-under and leads Nick Gillespie by a shot.
