The Masters 2015: Jordan Spieth maintains lead but Justin Rose and Phil Mickelson in contention

Jordan Spieth remains on course to claim his maiden major title despite having his Masters lead cut to four shots after a stunning 67 from Justin Rose set up a fascinating final day at Augusta.

Spieth (16-under) was on course for a record score after 54 holes but a double-bogey at the 17th coupled with five birdies in six roles from Rose (12-under) means the Texan has a narrow lead to protect going into the final round.

"The back nine was a lot of fun," Rose said. "The putt at seven got things going. Holeing the bucker shot on 16 was a bonus and the birdie on 18 gives me a lot of momentum going into the final day."

Two-time champion Phil Mickelson (11-under) is also in contention going into the fourth round after a 67 thrust himself up the leaderboard but dropped shots and missed chances on the back nine could yet come back to haunt him.

Charley Hoffman is a further shot back after a frustrating round but in truth the title is likely to be a three-horse race after a thrilling third day.

Rory McIlroy temporarily reignited his challenge before a bogey on the 18th left him requiring a heroic final round to figure in the final day shake-up at six-under, tied with Tiger Woods who produced a virtuoso display to enter the top ten.

"It could have been a really special round today, I could have gone really low," Woods said. "I made a crazy birdie at 13, stupid bogey at 14, stuffed it at 17.

"We saw what happened in 1996 [when Greg Norman blew a six shot lead on the final day], so anything can happen.

"On this course you can play well, but if you miss your spot by a foot then the next thing you know you have a 50-footer. It has been so hot and humid that the greens have not sped up."

Kevin Streelman, Kevin Na and Dustin Johnson are also on six-under but the final day in Georgia could yet be a coronation of Spieth, with the 21-year-old honing in on eclipsing Woods' record win of -18 in 2000.

Leaderboard: -16: Spieth, -12: Rose, -11: Mickelson, -10: Hoffman, -6: McIlroy, Woods, Streelman, K. Na, D. Johnson, -5: Matsuyama, Casey
