England's Chris Williams, inspired by a hole in one and aided by a dramatic final-round collapse by runaway leader Zaw Moe of Burma, won the US$200,000 Volvo Masters of Malaysia at the fourth play-off hole yesterday. The rain which had affected play at the Kota Permai Golf and Country Club in Kuala Lumpur on the first three days stayed away as one of the most exciting finishes on the Omega Tour unfolded. Williams, in the play-off with Moe and Australia's Adrian Percey, sank a 20-footer for birdie on the par-five 18th to claim the US$32,300 first prize. Percey, sensationally disqualified for taking an illegal buggy ride in last week's Sabah Masters, was eliminated at the first extra hole. Canada's Jim Rutledge, who fired a hole in one on the 17th just 15 minutes after Williams' ace, missed out on the play-off by a stroke. 'It has been five years since my last victory and I am totally overwhelmed,' said Williams, whose final-round 69 included the ace at the 14th. 'Never at any stage during the round did I think I could win.' Japanese Tour regular Moe completed his rain-interrupted third round yesterday with a 67 and took a six-shot lead into the final round. The 31-year-old extended his lead with a birdie on the first hole but then faltered badly with a procession of dropped shots. 'I felt unsettled right from the start - I could not stop pushing my shots,' said Moe.
