Cameron Smith holds the 36-hole lead at the 150th Open Championship after a day on which Tiger Woods likely waved a fond farewell to St Andrews.
A stellar 64 from Smith handed the Australian a two-shot lead on 13 under at the halfway point, with Cameron Young his nearest rival, while the likes of Rory McIlroy, Dustin Johnson and Scottie Scheffler are firmly in the mix.
But 15-time major winner Woods, who has his name etched onto the Claret Jug three times, missed the cut following an untidy 75, conceding afterwards that he would probably not be returning when the home of golf next hosts the sport's oldest major.
Woods was met with rapturous applause as he made the walk down the 18th fairway, with McIlroy tipping his hat to the American as he headed down the first at the start of his round of 68, which left the 2014 winner three shots behind, level with Viktor Hovland.
After early rain on the Fife coast, the conditions were conducive to low scoring and Smith was one of a host of players to take advantage, with compatriot Adam Scott's 65 moving him to seven under and Tyrrell Hatton's 66 leaving him one better off.
Johnson got to nine under with a 67, one ahead of world number one Scheffler.
Other big names to join Woods in missing the cut were reigning champion Collin Morikawa, six-time major winner Phil Mickelson and four-time major winner Brooks Koepka.
SHOT OF THE DAY
Smith headed to the par-five 14th on the back of three consecutive pars and looking for something to ignite his back nine to match the fireworks of the front nine.
And my word did he find it. His approach shot found the green but was a long way from the hole, leaving him with surely a lag putt just to put it close enough for a birdie.
But that was never going to be enough for the on-form Smith, who rolled it all the way up to the hole and in the cup for a spectacular eagle.
PLAYER OF THE DAY
Smith's 64 was Friday's lowest round on a day when his scorecard remained blemish-free.
The 28-year-old's putter stayed hot as he made six birdies and an eagle en route to a score that puts him in firm contention for a maiden major.
CHIPPING IN
Tiger Woods: "This is my favourite golf course. I fell in love with it back in 1995 and it hasn't changed. I just love how it can be played in so many different ways."
Mark Calcavecchia: "Forget about my golf. It wouldn't have mattered if I shot a pair of 75s or a pair of 85s, which I nearly did. It was about playing one more, my last one here at the home of golf, which is really cool to be able to end it here."
Cameron Smith: "I think there's going to be a few more gnarly pins, and I think being smart out there is definitely going to be the key to staying at the top of the leaderboard."
A LITTLE BIRDIE TOLD ME
- Cameron Smith's combined score of 131 is a record after 36 holes in an Open at St Andrews.
- All four past champions at St Andrews missed the cut: Zach Johnson (2015), Louis Oosthuizen (2010), Tiger Woods (2000, 2005) and John Daly (1995).
- From his 22 appearances at The Open, this was only the fourth time Woods failed to make the cut.
