Reno, Nev. ? Greg Chalmers birdied five of his last eight holes to take a two-point lead in the Barracuda Championship, the PGA Tour’s only modified Stableford scoring event.

The 42-year-old Australian had a 10-point round to reach 24 points at Montreux in the scoring system that awards eight points for double eagle, five points for an eagle, two points for a birdie and deducts a point for a bogey and three points for a double bogey or worse.

First-round leader Martin Laird of Scotland bogeyed three of his last six holes — finishing with a three-putt on the par-4 ninth — to drop into a tie for second with 2013 winner and former Kansas University golfer Gary Woodland. Laird also had five birdies in a seven-point round. Woodland had eight points with five birdies and two bogeys.
