KAUPULEHU-KONA, Hawaii (AP) David Frost of South Africa had a 7-under 65 Friday to take a one-stroke lead after the first round of the Mitsubishi Electric Championship.
The tournament opens the 34th Champions Tour season at Hualalai Golf Club.
The field of 40 has champions from the past two years and major champions from the past five, plus eight sponsor exemptions.
Frost made a 40-foot eagle putt on the seventh hole to reach 5 under. His only bogey came on the next hole and three birdies on the back nine put him into the lead.
Kirk Triplett, the 2012 Champions Rookie of the Year, bogeyed the last hole to fall into a six-way tie for second at 66. He shares that spot with 63-year-old Tom Kite, Willie Wood, John Cook, Fred Couples and Tom Lehman, the senior tour's Player of the Year in 2011 and 2012.
John Huston, Russ Cochran and Kenny Perry are another shot back.
Australian Steve Elkington had a 68 in his senior debut and is tied for 11th with Corey Pavin and Jay Haas.
Only eight players, including defending champion Dan Forsman (73), failed to break par in calm conditions at Hualalai.
