In-form Aussie Adam Scott has extended his lead at the top of the table with a round to play at the St Jude Championship in Memphis. Scott has put himself in position to lead the event from start to finish after firing a two-under 68 at the unforgiving Southwind course on day three. The lead-up event to next week&aposs US Open could provide Scott with a timely confidence boost on the major&aposs eve. The skilled Scott has carded three straight rounds in the 60s to enter the final day at nine-under, three strokes clear of David Toms (66) and Brian Gay (70). Despite his solid form to this point of the tournament, Scott knows the trophy isn&apost quite in the bag. “Three shots is nothing, really,” Scott said. “That&aposs a couple-hole turnaround out there. I mean, there&aposs plenty of trouble to get in on this golf course. The pins are in quite difficult positions, and they have been every day. If you get out of position, it&aposs hard to get back in.” “Three shots is definitely not a big enough lead as far as I&aposm concerned. It&aposd be nice to get off to a good start tomorrow and make it hard for them to catch me.” Scott – who had two front nine bogeys and four birdies for the round – did relinquish the lead briefly when Gay made him pay for a wayward stretch early. Within three holes of handing over the advantage, however, Scott had reclaimed it and his name was slotted back atop the leader board. Scott&aposs form this week has impressed Toms. “He&aposs the next superstar if he&aposs not already,” Toms said. “He&aposs a nice fellow and good for the game of golf. He&aposll be tough. Obviously, he&aposs won this year already. He played well last week. He&aposs obviously on a roll right now.” Fellow Australian Andrew Buckle undid all the good work of his second round 66 when he served up a five-over par 75 on moving day. He will begin the final round at one-over while Robert Allenby is one-under after three rounds. Meanwhile, the colourful John Daly is tied for 58th after an interesting week. On Friday he accused his wife of waking him up that morning and attacking him with a steak knife.
