5:45 am: A tricky par save drops for Young; he has putted the lights out this week. McIlroy also makes four.

5:40 am: Russell Henley is making a big move up ahead. He joins McIlroy at 10 under after a birdie on 8.

Justin Rose, take a bow. After missing his drive right, pinestraw beneath his feet, tree trouble all around, Rose hits an unbelievable cutting iron shot which caught the slope on the green and fed to about a foot. He has the putt get to -10.

5:30 am: McIlroy makes a mess of the par-3 4th, misses the green left and three-putts, has to pencil in a double-bogey. Young leads by two at Augusta.

The luck of the Irish isn't there on this front side. Lowry makes a double on 5 after having two shots in the fairway bunker.

5:20 am: A nice bunker shot from a friendly lie for McIlroy, and he rolls his putt in. First birdie of the day for the defending champion. Young saves par, 12 under leads.

5:10 am: A great break for Young, a wayward tee shot kicks out of the trees and just short of the green. McIlroy finds the greenside bunker with his drive. 

5:00 am: McIlroy's putt slides by. The final group heads to the drivable par-4 3rd. Young has the lead on his own at -12.

5:00 am: A beautiful wedge from McIlroy after laying up on 2, he spins one off the slope and has a makeable birdie putt back up the hill. Young narrowly evades sand trouble and has a slightly longer chance, which he makes.

Burns in strife again at 3. Not advancing his greenside bunker shot out of the trap.

4:50 am: Double for Burns. Lowry makes birdie to steal back the shot he lost at the 1st.

4:50 am: Trouble for Burns at 2, finding trouble off the tee. He has hit his 4th long of the par 5 and is staring down the barrel of bogey or worse.

4:45 am:  After a great shot into 1, McIlroy doesn't give his putt a chance, settling for par. Trading fours at 1 for the final group.

Day and Rose can't capitalise on birdies at the 2nd either.

Up ahead, Scheffler plays a delicate bunker shot at the short par-4 3rd, setting himself up for another birdie. Just two back now.

4:40 am:  Don't forget about Burns! He makes a birdie at the 1st to join the lead of 11 under. There are three at the top!

4:30 am: After missing the green to the right on 1, Rose chips in on the first! It was going nowhere but the bottom of the jar. What a start for the multi-time nearly man. He is just two shots back at nine under. The drama begins.

 

 

Rory McIlroy and Cam Young start their final rounds. 

Both taking less than the driver, Young cuts one a little much and finds the fairway bunker, while McIlroy makes a confident swing and finds the fairway.  

4:15 am: Jason Day gets his Sunday surge underway by finding the fairway bunker on 1. Justin Rose finds the fairway with an excellent drive.

The penultimate group of Shane Lowry and Sam Burns are on the tee.

4:10 am: Birdies are flowing from those out on the course, most notably Viktor Hovland, who was seven under through 14 holes. Scottie Scheffler has started his charge with a birdie at the 1st; the world No.1 is just three back and no doubt making his peers a bit nervous. 

Jordan Spieth holes out from the bunker on 13, the first eagle of the day on the par-5.
