Brandt Snedeker has completed his second bogey-free round to take a one-shot lead over Australian Adam Scott at the midway point of the British Open.
The 31-year-old American hit six birdies on Friday in a six-under 64 round, taking the overall lead at 10 under for the tournament, one shot ahead of Scott, who struggled early but finished his round strongly.
From the outset Snedeker looked in fine touch, producing a birdie at the first hole before adding another three birdies in the final four holes on the front nine.
Consecutive birdies on the 11th and 12th holes followed giving Snedeker a second-round score of 64, which was the best of any player on Friday at Royal Lytham & St Annes.
Snedeker's bogey-free second round backed up from an opening score of four under on Thursday where he did not drop a shot.
Scott, meanwhile, who went into the second round at the top of the leaderboard, but finished the front nine on even par for the day after a birdie and a bogey.
However, three more birdies on the back nine saw the 32-year-old card a three-under 67 round seeing him head into Saturday's third round on nine under overall.
Scott saw five of his countrymen join him for the weekend's action by making the cut, with Brendan Jones (three over) the most fortunate of the lot, scraping in right on the cut line.
Greg Chalmers is the second-best placed Australian at one over, after carding a two-under 68 for his second round to be tied for 15th at one-under overall.
Geoff Ogilvy also shot two under on Friday to be tied for 28th on even par for the tournament, while John Senden shot a one-over 71 to follow on from his opening round of even par to sit in a tie for 40th.
Aaron Baddeley made it back-to-back rounds of one-over 71s to sit in a tie for 51st place, one stroke ahead of Jones after a four-over 74 on Friday saw him head into the weekend at three over for the tournament.
Further up the leaderboard, Tiger Woods is outright third at the Open Championship after also completing a round of 67.
Woods needed a birdie on the 18th hole to match Scott's round and chipped in from a bunker to spark the crowd and complete a solid second day.
Denmark's Thorbjorn Olesen is fourth on five under, one stroke ahead of Scotland's Paul Lawrie, South Africa's Thomas Aiken, Matt Kuchar and Jason Dufner of the USA, as well as Northern Ireland's Graeme McDowell.
Ernie Els rounds out the top 10 at three under, seven shots behind Snedeker.
World number one Luke Donald is part of a group of four on two under for the tournament.
The big names to miss the cut included American Phil Mickelson, Germany's Martin Kaymer and Spaniard Sergio Garcia.
However, five-time Open champion Tom Watson of the United States delighted the crowd, as the 62-year-old sunk a long putt to make the cut for a second consecutive year.
Four Australians missed the cut by a solitary stroke, including PGA Tour winner Marc Leishman, Marcus Fraser, Nicholas Cullen and Aaron Townsend - with the quartet all at four-over.
Ashley Hall carded a round of five-over 75 to finish at six over, while Robert Allenby signed off on a two-over 72 on Friday to be seven-over overall. Brad Kennedy finished on eight-over par.
