Australian Aaron Baddeley moved up two places and carded his second successive 66 to take a one-point lead at the half-way point of the Barracuda Championship.
Baddeley, 37, hit six birdies and did not drop a shot at the Montreux Golf and Country club, with his round giving him an overall score of 26.
Baddeley sits four points clear of Shane Lowry, who followed an opening round of 68 with a 67 on Friday - picking up 12 points in the process. Lowry now has 22 points, and is in a share of sixth place.
Séamus Power is tied for 13th on 18 points after a second round of 68 (10), while Graeme McDowell and Padraig Harrington both crept inside the cut mark after picking up seven points across their first two rounds. McDowell shot a 71 (3) on Friday, Harrington a 73 (1).
Meanwhile round-one leader Ollie Schniederjans is a point behind Baddeley following a costly bogey on the third and an even more costly double-bogey on the par-3 seventh.
Three Americans — John Merrick, Andrew Putnam and Sam Saunders — are tied for third on 23 points, three behind the leader.
The Barracuda Championship — formerly known as the Reno-Tahoe Open — uses a Modified Stableford format, which allocates points based on the number of strokes taken at each hole.
Eight points are awarded for an albatross, five for an eagle, two for a birdie, zero for a par, minus one for a bogey and minus three for a double bogey or worse.
