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 the world's top players competing at Augusta National this year.

No. 9: Raymond Floyd, Round 1, 1976

Raymond Floyd's 65 in the opening round of the 1976 Masters was the lowest round of that year's tournament. Along the way to his record-setting victory, he set the mark for low 18-hole score, as well as for 36 and 54 holes. His 17-under-par total matched Jack Nicklaus' record, too.

Floyd's 66 in Round 2 was tied for the second-lowest round of that year's Masters and helped propel him to an 8-shot victory.
