Summaries of the last two PGA Championships at Whistling Straits:

YEAR: 2010

WINNER: Martin Kaymer

SCORE: 277

MARGIN: Playoff

RUNNER-UP: Bubba Watson

PRIZE MONEY: $1.35 million.

SUMMARY: Martin Kaymer won his first major in a playoff over Bubba Watson, and yet this PGA Championship is remembered as much for who wasn't in the playoff. Dustin Johnson had a one-shot lead playing the final hole when he set his 4-iron in sand that he thought was the base of a dead patch of grass. Instead it was among the 1,000 bunkers at Whistling Straits. After missing a 7-foot par putt on the final hole, he was penalized two shots and wound up in a tie for fifth. Kaymer and Watson were tied playing the 18th in the three-hole playoff when Watson hit his approach into the water and made double bogey.

NOTABLE: Nick Watney had a three-shot lead going into the final round and shot 81. ... Matt Kuchar tied for 10th to earn the final spot on the U.S. Ryder Cup team, bumping out Anthony Kim. ... Rory McIlroy missed a 20-foot birdie putt on the last hole that would have put him in the playoff.

QUOTABLE: "The only worse thing that could have happened was if I had made the putt on that last hole." — Dustin Johnson.

YEAR: 2004

WINNER: Vijay Singh

SCORE: 280

MARGIN: Playoff

RUNNER-UP: Justin Leonard, Chris DiMarco

PRIZE MONEY: $1.125 million.

SUMMARY: Vijay Singh closed with a 76 — the highest final round by a winner in PGA Championship history — and only got into a three-man playoff when Justin Leonard's putter let him down. Leonard missed a 12-foot par putt on the 18th hole, his sixth miss inside 12 feet on the back nine. Chris DiMarco had a chance to win in regulation and left his birdie putt short. In the three-hole playoff, Singh opened with a birdie and the others couldn't catch up. Singh won his third major.

NOTABLE: Singh did not make a birdie over the final 18 holes in regulation. ... Tiger Woods tied for 24th and narrowly kept his No. 1 ranking to break Greg Norman's record with his 332nd week at No. 1. ... Ernie Els three-putted from long range on the final hole and finished one shot out of the playoff. That capped off a year in which Els finished one behind Phil Mickelson in the Masters, lost a playoff against Todd Hamilton in the British Open and shot 80 in the final round of the U.S. Open playing in the last group.

QUOTABLE: "I think this is the biggest accomplishment I've ever had in my whole career." — Vijay Singh.
