Angelo Que led the chase of overnight leaders Rhys Davies and Ignacio Garrido on the second morning of the Maybank Malaysian Open at Kuala Lumpur Golf & Country Club.
The 31-year-old Filipino reeled off four consecutive birdies in the middle of his front nine to reach the turn six under par overall and just a shot adrift of clubhouse leaders Davies and Garrido.
Last year Que qualified for the US Open Championship but missed the cut by two strokes, while also finishing tied for seventh at the Omega European Masters.
Yesterday, Challenge Tour graduate Davies blazed a flawless 65 to top the leaderboard alongside Garrido, who dropped just one shot in his seven under par first round.
In-form Asian number one Thongchai Jaidee and South Korea's Kim Dae-hyun led the chasing pack at six-under-par overnight with the first round leading contenders set to resume their challenges later.
Australia's Scott Strange picked up two birdies over his opening eight holes of the friendly front nine of the West course to progress to five under par alongside Chinnarat Phadungsil.
The Thai was one of 30 players who returned on Friday to complete their first rounds after a thunderstorm suspended play on Thursday and was able to pick up a seventh birdie to card a five under par 67.
Peter Lawrie had progressed nicely to five under par with two gains over his opening three holes, but the Irishman shipped a disastrous quintuple bogey 10 at the par-five fifth to plummet back to level par overall following yesterday's opening three under 69.
He did quickly return to red figures with a third birdie to the day to reach the turn in two over par.
