Davis Love III and Stuart Appleby shot 4-under 66 on Thursday for a share of the lead with four other players after the first round of the St. Jude Classic.
Harris English, Nathan Green, Martin Flores and Glen Day also pushed their way into the lead on a day where at least three others had a piece of the top spot lead at some point.
Defending champ Dustin Johnson was 5 under through six holes, talking advantage of near perfect conditions at the TPC Southwind with a temperature in the low 80s and only a slight breeze early. But Johnson finished with a 67 and was tied with 10 others including David Toms, a two-time winner here, and Shawn Stefani, who was tied for the lead before he hit into a fairway bunker and bogeyed No. 18.
Phil Mickelson opened with a 71.
