(Blaine, MN)  --  Rickie Fowler and Jhonattan Vegas shot matching bogey-free, seven-under 64s to jump to the top of the leaderboard at the 3M Open in Blaine, Minnesota.  Also tied for the lead is Troy Merritt, who tallied eight birdies, but bogeyed the ninth hole to fall back.  Scott Stallings and Adam Schenk are a stroke back at six-under, as is Roger Sloan, but he only finished 16 holes on Thursday.  Defending champion Michael Thompson had a rough go of it, shooting a one-over 72 in the first round.
