ESPN golf analyst and two-time major champion Andy North put together his list of the 10 greatest rounds in Masters history.

ESPN.com will roll out his rankings on a daily basis leading up to this year's Masters at Augusta National, where the world's top players will compete for the green jacket.

No. 1: Jack Nicklaus, Round 4, 1986

Jack Nicklaus owns 506 career birdies in his Masters career, but the most magical ones might have come during his back-nine charge in 1986.

With his son on the bag, Nicklaus carded a final-round 65 with a 30 on the inward nine after going eagle-birdie-birdie from Holes 15-17.

At age 46, Nicklaus claimed his sixth green jacket in what many refer to as the greatest Masters in history.
