Buha, who has missed 14 of 20 cuts on the PGA Tour in 2000, fired a career-low round of 6-under-par 65 to tie Grant Waite, Doug Barron and Dave Stockton, Jr. for the top spot after 18 holes at the Northview Golf and Country Club.
Currently 185th on the money list, Buha carded nine birdies and three bogeys on Thursday. The 25-year-old Duke Blue Devil qualified for the Tour this season after finishing tied for 34th at the Qualifying Tournament. His best finish in 2000 came in a tie for 18th at the Canon Greater Hartford Open.
Of the quartet tied at the top, Waite is the only one with a Tour victory under his belt. The Kiwi's lone triumph came at the 1993 Kemper Open. Waite posted six birdies and no bogeys in the first round.
Stockton, who started at the 10th, shot a front-nine 31 to move into a share of first place. Likewise, Barron fired an outward 4-under-par 32 to kick-start his round of 65.
Jesper Parnevik leads a group of six players one shot off the overnight lead. Despite a poor session on the practice range prior to his round, the 2-time 2000 Tour winner reeled off six birdies to just one bogey for a 5-under-par 66.
Parnevik is currently fifth on the PGA Tour in earnings, thanks to victories at the Bob Hope Chrysler Classic and the GTE Byron Nelson Classic.
Money is something Australian Craig Parry has never had a problem collecting in the States. Wins, however, are another story. Parry has garnered over $3.7 million dollars in nine full seasons on the PGA Tour without nabbing a victory. When Kirk Triplett won this year's Nissan Open, he passed along the dubious distinction of most money earned without a win to Parry.
Tommy Tolles is also tied for fifth. Tolles birdied four of his first five holes on Thursday, but managed only two more birdies and a bogey the rest of the way.
