Matt Jones fired the lowest round of his fledgling career to soar into fifth place behind winner Nick Watney at the Buick Invitational at Torrey Pines. The 28-year-old Australian earned one his biggest paydays on the PGA Tour after shooting a day&aposs best eight-under 64 to finish at seven-under for the tournament. Compatriot Mathew Goggin also secured a top-10 finish, one stroke further back in outright sixth place. New South Wales-born Jones, who finished 23rd at this tournament last year, missed just two greens during his round, which included 10 birdies and two bogeys. “My goal is normally just to try and hit as many greens as possible, and today I did,” he said afterwards. “My putting stroke has been feeling good all week, and I just made some putts today.” Watney shot two birdies in the final three holes to overrun John Rollins and claim his second PGA title with an 11-under total. Watney began the day five shots adrift but his round of four-under was enough to clinch victory by one stroke. Rollins stumbled to a two-over 74, while Colombian Camilo Villegas could only manage an even-par round to finish in a tie for third with Lucas Glover, who posted a 68. After graduating from the Nationwide Tour at the end of 2007, Jones made significant in-roads last year to finish 135th on the money list. His best finishes in 2008 were ties for fourth at the Honda Classic and Buick Open. Jones said he enjoyed the anonymity when he returned to Sydney to play the Australian Open in December (he finished in a share of 24th) but admitted his results on the PGA Tour this year would earn him more recognition. “It&aposs fun just to go home and play in front of your friends and family since they&aposre never over here to see you play too often. I played well in the Aussie Open,” he said. Of the other Australians, Aaron Baddeley (72) was tied for 11th at four-under, Marc Leishman (74) was even in a share of 26th and Aron Price (72), Jason Day (74) and Rod Pampling (70) tied for 35th place. Jarrod Lyle (75) and Nathan Green (76) had disappointing final rounds to drop into a share of 42nd. John Senden (72), James Nitties (74) and Stuart Appleby (73) were well down the leaderboard.
