Australia&aposs Adam Groom will carry a one-stroke advantage into the final round of the Johnnie Walker Cambodian Open on Sunday. Groom held on to his narrow lead over American Bryan Saltus courtesy of a two-under-par 70 on Saturday. Currently ranked 47th on the Asian Tour&aposs UBS Order of Merit, Groom is eyeing his maiden title this season and did little harm to his chances when he shot three birdies and dropped just one shot to be 13-under-par with a round to play. American Saltus stayed in contention after a 71, while the Thai trio of Thaworn Wiratchant, Chapchai Nirat, and Prom Meesawat are four strokes behind the leader in joint third spot having fired a 67, 68 and 69 respectively at the Phokeethra Country Club. England&aposs Yasin Ali, who is ranked 70th on the money list, kept his hopes alive for a card next season when he blasted his second straight 68 to lie in lone seventh spot. Groom, 28, was two-under-par after 10 holes and held on to a one stroke advantage when he parred the remaining eight holes on the way home. “I guess knowing that I have secured my card for next year has helped me relax on course this week,” Groom said at the conclusion of his round. “I haven&apost played four rounds under par this season and doing that this week would be a great result.” “The conditions are not that tough and with a solid game tomorrow, it might just work out. I don&apost really feel any pressure especially after my round with my friend Bryan today. It was nice out there.
