Nicklaus was the youngest golfer ever to win two Masters, and he'll retain that distinction even if Tiger wins this year because Tiger's birthdate is December 30 and Jack's is January 21. Should Tiger win The Masters, it will be his sixth major victory in just his 17th major start as a pro. In his 17th major start as a pro, Jack won the 1966 Masters for his fifth major victory. He then won the 1966 British Open for his sixth major in his 19th major start as a pro. He was 26 in 1966 and the youngest to win six pro majors.
Tiger is the youngest to win five pro majors.
Besides his streak of three consecutive major victories, Woods takes some other streaks into Augusta. His last nine rounds in the majors have been under par. Woods is currently riding a streak of 18 consecutive rounds at par or better in PGA Tour events and 22 in a row overall if you include the Dubai Desert Classic, a European Tour event. He has shot par or better in 73 of his last 75 rounds in PGA Tour events, including 52 consecutive rounds of par or better at the start of this stretch. His only other round over par was a 2-over 73 in the second round of the Phoenix Open at the TPC at Scottsdale.
