Steve Stricker upstaged playing partner Tiger Woods to earn a share of the lead with fellow American Jim Furyk after the opening round at the Deutsche Bank Golf Championship.
Stricker notched eight birdies, including five in a row, to card an impressive eight-under-par 63 in at the Boston TPC.
Stricker and Furyk lead by two strokes from a large group including South African Retief Goosen, who eagled the par-five 18th from 40 feet, and Masters champion Angel Cabrera of Argentina.
Woods, aiming to ease the sting of a rare season without a major title, had little positive to say about his opening round after battling to a three-birdie two-bogey 70.
The Deutsche Bank Championship is the second of four events in the PGA Tour's FedEx play-off series after the Barclays Classic, won by American Heath Slocum in New Jersey.
Only the top 70 in points rankings will advance to next week's BMW Championship near Chicago.
The overall winner takes $10 million dollars US in prize money.
