Harris English shot a 6-under 64 on Friday to open a two-stroke lead in the St. Jude Classic.
The 23-year-old former Georgia player had never even had a piece of a lead on the PGA Tour until Thursday when he found himself tied with five others, including Davis Love III, after 18 holes.
English used a hot putter to roll in five birdie putts, holed out from 181 yards for eagle on the par-4 fifth and had only one bogey to finish the second round at 10-under 130.
Shawn Stefani was second after a 65. Paul Haley II and Scott Stallings each shot 68 to reach 5 under. Love was tied with four others at 4 under after a 70, and defending champion Dustin Johnson also had a 70 to finish at 3 under. Phil Mickelson was 2 under after a 67.
Only four players had rounds of 4 under or better on a near perfect day at TPC Southwind.
