Shawn Stefani takes one shot lead at St Jude Classic

PGA Tour rookie Shawn Stefani rebounded from a quadruple-bogey at the 11th to edge one stroke clear of playing partner Harris English in the third round of the St Jude Classic in Memphis, Tennessee.

American Stefani, seeking his first victory on the US circuit, piled up eight birdies on the way to a 4-under-par 66 on a warm, mainly overcast day at the TPC Southwind, finishing at 12-under 198.

Compatriot English, who had been two strokes in front overnight in pursuit of his maiden PGA Tour title, rolled in a 14-footer to birdie the last for a 69 to secure outright second place.

PGA Tour rookie Patrick Reed fired the day's lowest score, a six-birdie 64 lifting him into a tie for third at 8-under with fellow Americans Nicholas Thompson (66) and Scott Stallings (67).

Four-times major champion Phil Mickelson also mounted a charge on what is traditionally known as 'Moving Day' at golf tournaments, a 65 putting him at seven under alongside rookie Eric Meierdierks (66).

Several other big names were also in contention with triple major winner Padraig Harrington of Ireland (65) at 6-under, a stroke better than Englishman Ian Poulter and defending champion Dustin Johnson of the US who returned matching 68s.

Australia's Nick O'Hern was eight strokes behind Stefani, tied for 18th place on 4-under, while compatriot Robert Allenby was a tie for 41st, two strokes further back.
