The fortress that Rory McIlroy had built over two rounds at Augusta National crumbled in spectacular fashion Saturday, as his six-stroke cushion evaporated into a tie for the lead heading into what promises to be a thrilling final round at the Masters.
McIlroy's third-round 73 opened the floodgates for a charging field that produced the lowest third-round scoring average in Masters history at 70.63. The Northern Irishman now shares the lead at 11 under par with Cameron Young, while six other players lurk within four shots.
"The course was obviously gettable," McIlroy said after surrendering his commanding position. "There was a lot of good scores out there, and obviously the quality of the chasing pack is obvious. There was a lot of guys that shot good scores."
The catalyst for McIlroy's struggles proved to be his wayward driving, as he ranks dead last in driving accuracy among players who made the cut. That inconsistency off the tee prevented him from continuing the birdie barrage that built his massive Friday lead and ultimately led to disaster at the par-4 11th hole.
At the treacherous 11th, McIlroy found the water hazard and carded a damaging double bogey that further deflated his cushion. The mistake highlighted how quickly fortunes can change at Augusta National, especially when precision abandons a player's game.
"I'll probably give myself some time to think about it right now for the next 30 minutes or so. After that, it's kind of a battle of managing how you want to react to those things," Young said. "To me, it's just a matter of going right back to how am I going to run my day tomorrow, what time am I going to get here, so I can eat, so I can go see the physio? It's just going to be back to my routine, and that's what I'm going to lean on."
The final pairing carries significant historical weight, as McIlroy sits at No. 2 in the world rankings, one spot ahead of Young at No. 3. The last time two players from the top three in the rankings shared the final group at the Masters was 2001, when Tiger Woods and Phil Mickelson battled for the green jacket, with Woods ultimately prevailing by two strokes over David Duval.
World No. 1 Scottie Scheffler injected himself into contention with a sizzling 65 that moved him to within four shots of the leaders. Sam Burns trails by just one shot at 10 under, while Shane Lowry sits another stroke back at 9 under par.

Jason Day and Justin Rose round out the group at 8 under, with Rose drawing on experience from last year's runner-up finish. The Englishman shot 66 in the final round last year to force a playoff before ultimately falling to McIlroy.
"The whole field is not going to help you out, put it that way," Rose said. "It's going to take a special round tomorrow, so there's a chance, which is great. I'm going to try to channel a bit of last year and see what happens."
McIlroy enters Sunday's final round attempting to become just the fourth player in Masters history to successfully defend his title. However, his driving woes and the depth of quality chasing him suggest he'll need to rediscover the form that carried him to Friday's commanding position.
