DUBLIN, Ohio -- Scott Piercy rode a string of five straight birdies to a front-nine 31 that has given him a one-stroke advantage early during the first round of the Memorial Tournament presented by Nationwide Insurance.
Piercy, who has won a PGA TOUR event each of the last two years, is 5 under. He made birdie putts of 10, 9, 10 and 5 starting at No. 4, then holed it from 40 feet in the fringe on No. 8.
South Africa's Charl Schwartzel, Scott Stalliings and Cameron Tringale are one back through eight, seven and seven holes, respectively. Stallings, who started on the back nine, was briefly tied with Piercy when he holed a bunker shot for eagle at the 15th hole, but he dropped back into the tie for second when he bogeyed the next.
Josh Teater is alone at 3 under through four holes. Davis Love III, who was named an assistant captain for the Presidents Cup on Wednesday, heads a big group at 2 under that also includes Luke Donald, Billy Horschel, Carl Pettersson, David Ernst, Matt Jones, David Lingmerth, Charlie Wi and Graham DeLaet.
World No. 2 Rory McIlroy is 3 over through eight holes. Tiger Woods, the game's No. 1 player, tees off at 1:16 p.m. ET.
