Jack Nicklaus holds the record for most major victories with 18, and Woods has finally reached the halfway point with nine after a drought that lasted almost three years.
Woods was miles ahead of everybody earlier in his career and owned all four major titles at the same time following his second Masters victory in 2001. He came back the next year with his third title at Augusta and then won the U.S. Open in the summer of 2002 at Bethpage.
Nicklaus won the first two majors of the season in 1972 and was halfway to the single season grand slam when he went to Muirfield for the British Open. Nicklaus finished second to Lee Trevino, however.
Woods had a poor showing at Muirfield and tied for 28th in 2002. He then finished second to Rich Beem at the PGA Championship before going without a major in 2003. Woods then failed to win a major in 2004, but the new World No. 1 is showing signs of his old self so far this year with multiple victories and now his ninth major title.
'I've kind of battled the last couple of years to work hard on my game and make some changes,' said Woods, who won for the 43rd time on the PGA Tour. 'I wasn't winning major championships and I contended a couple times and didn't win. But for the most part, I wasn't in contention on the back nine on every major like I like to be. That's where you want to be. It was nice to get back there again and be in contention with a chance to win coming up the back nine on Sunday. It's a thrill.'
At 29, Woods is younger than Nicklaus was when he won his ninth, the 1971 PGA Championship at PGA National. Nicklaus then won nine more majors, including his last at the 1986 Masters at age 46.
'I think it's pretty neat for me to have an opportunity to have won four before the age of 30,' Woods said. 'No one's done that, so to be able to do something that no one has ever done is pretty neat.'
What's next for Woods this year?
Woods heads back to Pinehurst for the U.S. Open. He tied for third in 1999.
Woods also returns to the Old Course at St. Andrews, the site of his only British Open title and where Nicklaus, who said goodbye at the Masters on Saturday, will be making his last appearance at the oldest championship in the world.
Finally, Woods heads to Baltusrol for the PGA Championship in August.
