Geoff Ogilvy has continued his terrific run of form with a four-under-par 66 to trail Shigeki Maruyama from Japan by one stroke after the first round of the Sony Open in Hawaii. Ogilvy, who cruised to a six-stroke victory at the Mercedes-Benz Championship last week, is one of five players tied for second place including fellow Australian Nathan Green. Peter Lonard and Jarrod Lyle are a further four shots back after carding even par 70s to sit in a tie for 40th place. Aussie gun Adam Scott shot a one-over-par 71 to be in a tie for 51st place along with countryman Aron Price. The US dollar $5.4 million (AUD $7,957,837) event is the first full-field event of the season and the second straight in Hawaii. Maruyama looked in good touch from the outset, recording four birdies on the front nine. After a bogey on the par-four 12th hole dropped him to four-under, Maruyama recorded pars on four straight holes before birdying the 17th to take sole possession of the lead. Following his wire-to-wire win, the fifth of his PGA career, Ogilvy started his round on the back nine with a birdie and went on to record six birdies and two bogeys. Americans Boo Weekley, Brian Gay and Webb Simpson also shot rounds of 66 along with Green. Other notable players in the field of 114 players teeing it up on the 7,044-yard, par-70 course include Ernie Els and Steve Stricker. Els, who has enjoyed great success here since 2000, struggled to a two-over 72. The 39-year-old won this event in 2003 and 2004 and finished as runner-up in 2005. Els also was third in 2001 and fifth in 2000. Stricker is another player that has had success here, tying for fourth in each of the past two years. The American opened with an even-par 70.
