Rory McIlroy and Viktor Hovland will form Sunday's final pairing as the 150th Open Championship heads for a thrilling conclusion.

The duo played together on Saturday and both shot third-round 66s to claim a share of the lead on 16 under at St Andrews.

However, it is not quite a two-horse race at the famous Fife links, with Cameron Young and overnight leader Cameron Smith four strokes behind, while Scottie Scheffler and Kim Si-woo are within five.

The highlight of McIlroy's round was a hole-out eagle from the bunker on 10, but he and Hovland were both wayward on their approach shots to 17 as signs of nerves started to show on the notoriously tricky Road Hole.

McIlroy was close up against the stone wall to the right of the green and ended up with a bogey five, while Hovland – whose shot came to rest on the gravel path – recovered to salvage par and restore parity at the summit of the leaderboard.

A pair of birdies at the last kept it that way, setting things up for what promises to be a memorable final day at the home of golf.

Elsewhere in the field on an exciting moving day, Shane Lowry carded back-to-back eagles on the ninth and 10th before the 2019 winner faded on the back nine to sign for a 69.

Patrick Cantlay threatened to join the fun at the sharp end of things when he got to 11 under through 12, but he dropped three shots in the remaining six holes to end up eight off the pace.

SHOT OF THE DAY

McIlroy turned a threat into an opportunity after putting his tee shot into the bunker at the 10th, with rival Hovland having landed safely short of the pin.

A superb bunker shot pitched just shy of the cup and rolled in for an eagle two that piled the pressure on Hovland.

To his credit, the Norwegian got down in two for a birdie that ensured he stayed level with his playing partner.

PLAYER OF THE DAY

On moving day in Fife, it was crowd favourite McIlroy who really clicked into gear.

A pre-tournament favourite, the 33-year-old found his groove to chart a course for his fifth major and first since 2014.

On this form, he will take some stopping on Sunday, even with Hovland for company.

CHIPPING IN

Jordan Spieth: "What's difficult about it is a lot of the pin locations are in these tiny little tucked corners where, if you hit it more than five feet by, it goes 50 feet away."

Shane Lowry: "It wouldn't take Einstein to figure out what went wrong on the back nine. My putting was horrific."

Bryson DeChambeau: "I don't think you ever know how to play this golf course fully. Every day it's different. It showcases a unique golf course each time the wind pops up or doesn't pop up. It's just different."
