St. Andrews hosts the 150th British Open from Thursday with Rory McIlroy starting as the favorite for the Claret Jug while a determined Tiger Woods hopes to make an impact at a venue where he has triumphed twice before.

Record crowds for the week of 290,000 are expected on Scotland's east coast for this landmark edition of the world's oldest golf tournament, which comes to the Old Course for the 30th time.

With fine weather expected to continue for much of the week, it is shaping up to be a fitting way to mark a historic British Open, even if the sport continues to be rocked by the fallout caused by the breakaway LIV Series.

Players who left to join the Saudi-backed tour were allowed to take part by Open organizers, just as they were at last month's U.S. Open despite both the PGA Tour and DP World Tour moving to ban the rebels.

That means four-time major winner Brooks Koepka, Sergio Garcia, Bryson DeChambeau, Dustin Johnson and former Open champion Phil Mickelson will all tee off Thursday.

McIlroy, though, is aiming to end an eight-year wait to add to his four major titles and the Northern Irishman is the favorite in the eyes of bookmakers.

"I think it's the Holy Grail of our sport. So not a lot of people are going to get that opportunity to achieve that, but that's what winning an Open at St. Andrews is," McIlroy said on Tuesday.

The world No. 2 won the 2014 Open at Hoylake but missed the chance to defend his title in St. Andrews a year later after injuring an ankle playing football.

"I can't go in here thinking that this might be my time. I just have to go out and play a really good tournament," he added.

'A magical place'

McIlroy will tee off in Thursday's first round alongside Collin Morikawa, winner of last year's Open at Royal St George's, and Xander Schauffele, who triumphed in last weekend's Scottish Open.

There is no shortage of contenders, not least among the large contingent of American stars including world number one Scottie Scheffler and 2017 Open winner Jordan Spieth.

"If you're not getting amped up to play in this Open, I'm not sure this is the right sport for you," said Spieth Tuesday, when stiff breezes blowing across the course served as a reminder of the challenges St. Andrews can pose.

There has been some talk of the Old Course becoming too easy, 149 years on from the first Open here, but it still captivates players.

They will continue to be challenged in particular by the par-4 17th – the Road Hole is one of the toughest in golf, where players must send their tee shots over the Old Course Hotel.

Jack Nicklaus, twice an Open champion here and who was this week made an honorary citizen of the town, called St Andrews "a magical place."

Woods hits out at LIV rebels

Woods, now 46, won here in 2000 and 2005 and was determined to return despite suffering severe leg injuries in a car crash last year.

"For the most part of my rehab I was just hoping that I could walk again," admitted Woods, who skipped last month's U.S. Open to improve his chances of featuring this week.

"I'm not going to play a full schedule ever again. My body just won't allow me to do that.

"I don't know how many Open Championships I have left here at St. Andrews, but I wanted this one," said Woods, who will play with U.S. Open winner Matt Fitzpatrick in the first two rounds.

Woods, meanwhile, was outspoken in his criticism of the LIV rebels, who could yet end up being barred from featuring in majors in the future.

"I disagree with it. I think that what they have done is they have turned their back on what has allowed them to get to this position," he said.

While the Saudi-backed LIV Series offers record prize money of $25 million for each of its 54-hole events, British Open prize money totals $14 million.

McIlroy just hopes the winner's cheque does not end up in the hands of one of the rebels.

"Selfishly, for me, yes, I think it would be better for the game," he said.
