RENO, Nev. -- Sweden's David Lingmerth, who missed the cut in nine of his previous 12 PGA Tour events this season, held the lead when the first round of the Barracuda Championship was interrupted by lightning Thursday, July 25.

In the event's Modified Stableford scoring system, Lingmerth shot a plus-18 at Montreux Golf & Country Club. He holds a five-point lead on Robert Streb, Tom Hoge and South Africa's Tyrone Van Aswegen.

The format awards eight points for a double eagle, five points for an eagle and two points for a birdie. No points are awarded for par, with a bogey costing a player one point and a double bogey or worse earning a minus-3 score.

Lingmerth emerged with nine birdies and nine pars.

"It's been a little rough go for me for a little while and working my way back, and things are starting to come around," he told the Reno Gazette-Journal. "But I don't really think about it that way. I just try to stick to the process. One shot at a time. And whatever happens, happens."

Hoge and Van Aswegen each carded four birdies and an eagle. Streb had seven birdies and a bogey.

Two-time major champion John Daly, allowed to ride a cart in the event due to osteoarthritis in his right knee, is tied for 107th at minus-2. He made four bogeys before recording his lone birdie on the 18th hole.

David Duval, who shot a combined 27 over par in two rounds while missing the cut last week at the Open Championship, struggled again Thursday. The 2001 Open Championship winner finished last among the 130 players who completed the round, posting a minus-8. He had one birdie, four bogeys and two double bogeys.

The alternate-field event is running concurrently with the World Golf Championships-FedEx St. Jude Invitational in Memphis, Tenn.
