Woosnam - joint leader after superb 67.

Take your pick. Any one from over 20 players. Your guess is as good as anybody else's.

With a round to go in the Open championship at Royal Lytham - and after a day when there were so many changes on the leaderboard that it was hard to keep up - Ian Woosnam, David Duval and Germans Bernhard Langer and Alex Cejka are locked together at the top.

An incredible nine more, including Colin Montgomerie and Darren Clarke, are just a single shoot behind on the five-under-par mark of 208.

And the good news for all of the title hopefuls is that defending champion Tiger Woods, after a 73 that contained a double bogey seven on the seventh and two more bogeys after that, is only one under.

Not quite completely out of it, but with so many names to overtake highly unlikely to repeat his success of St Andrews last year.

Yet the 38-year-old Scot, who has been so close so often to a major, is still right in there with as good a chance as anyone.

For Woosnam to be sharing the lead at the age of 43 - and over four years on from his last tournament victory - is remarkable considering only a week ago he was not even sure of his place in the event. He had still to earn an exemption.

For Langer to be alongside him is perhaps even more stunning. He pulled out of the Scottish Open last Saturday morning after ricking his back putting some rubbish in a bin in his hotel room.

It was so bad he had to stop every hour on the journey south to Lancashire and he continues to have treatment every day.

And for Cejka to be in the position he is perhaps the most incredible of all.

When he was 10 years old, Cejka and his pianist father fled the communist regime in Czechoslovakia.

They were on holiday in Yugoslavia and swam across a river, then caught a train and made it to Germany.

It was there the youngster began playing golf - his inspiration being Langer, who came to play the German national championship at his home course.

He turned professional in 1989 and won the Volvo Masters in 1995, but he has not won since.

Last week at Loch Lomond he was disqualified for not signing his card.

He will not say as much, but he probably did it because he felt his best chance to play in the Open was to avoid the fight for 15 places on offer there and compete in the 36-hole final qualifying competition instead.

It has worked a treat. He shot 72-65 to be joint leader at Hillside and now has a real opportunity to repeat Paul Lawrie's feat of two years ago - come through the qualifying and win.

Duval is probably favourite now, though. He shot a best-of-the-day 65 to come from seven behind Montgomerie to joint leader, although he is only joint leader because Jesper Parnevik, out in front with two to play, double-bogeyed the 17th to go down from seven under to five under.

Also on that mark with Montgomerie and Clarke are Spain's Miguel Angel Jimenez, Frenchman Raphael Jacquelin, former winner Nick Price, Americans Billy Mayfair and Joe Ogilvie and another Swede, Pierre Fulke.

The changes at the top of the leaderboard began even before Montgomerie teed off again.

Duval went to the turn in 32 and when he birdied four of the next five he was alongside the seven-time European number one and also in with a chance of major golf's first-ever 62.

That was always unlikely, though, with Lytham's closing stretch as tough as it is and, sure enough, the former world number one bogeyed the 15th after driving into the rough and played them in one over for a 65.

The bogey put Montgomerie back in front, but Clarke then took a share of the lead with four birdies in his first seven.

They were to be the last the Ulsterman had, though, and bogeys at the ninth and 18th for a 69 left him just off the pace at five under.

Fulke was next to give Montgomerie company. He birdied the second and when the Scot missed from five feet at the fourth - the first real signs that all was not well with him - it was the Swede who was out in front on his own.

That remained the case until 43-year-old Langer caught him by following an outward 33 with three birdies in the next five.

Cejka joined them by reaching the turn in 32 and when he started for home with two birdies he was centre stage.

As the wind started to pick up - and he came to the most fearsome part of the course - Cejka buckled too, bogeying the 15th, 16th and 17th.

The second of those brought Mansfield's Greg Owen and Parnevik into a share for the lead, Owen having just leapt to seven under in the most dramatic way possible by holing his second shot to the 542-yard 11th.

Incredible in itself, even more so considering that on Thursday Jeff Maggert had an albatross as well - just the fifth in Open history - on the 494-yard fifth.

When Owen bogeyed the 16th - he actually finished disappointingly with three in a row - Parnevik led.

But that was not to last long either. It was that sort of day.

And if tomorrow is anything like it, nobody will ever forget this Open.
