McIlroy, Woods, Day and the lowest winning scores in PGA Championship history

The 105^th edition of the PGA Championship was wrapped up last weekend, with winner Brooks Koepka securing his third title.

Koepka shot -9 to win the championship, seven strokes worse than his previous best of -16 at the 2018 PGA Championship.

Over the years, golf's most incredible players have shot record-breaking scores at the PGA Championship.

With this year's PGA Championship in the history books, let's look at the lowest winning scores in the tournament's past!

Northern Irish superstar Rory McIlroy is still on the hunt for his first major since winning the PGA Championship in 2014, scoring -16 across 72 holes.

McIlroy recorded a 66, 67, and 67 in his opening three rounds, putting one shot in the lead on the final day. After falling to fourth in the final round after opening with two bogeys, McIlroy eagled the tenth and birdied the 13th and 17^th, taking him to -16.

Brooks Koepka landed a record-tying score of 63 in the second round of the PGA Championship in 2018, putting him in third place after being out of the top ten in the first 18 holes.

Koepka finished with two rounds of 66, producing a 72-hole score of 264, setting the PGA Championship record.

Former two-time Players Championship and PGA Championship winner Steve Elkington provided the golfing world with one of the most extraordinary comebacks in major history.

Going into the final day, Elkington was six shots behind leader Ernie Els, but an exceptional score of 64 led to Aussie jumping from fifth (-10) to winning the championship (-17), beating Els by two shots and securing victory in a playoff with Colin Montgomerie.

Tiger Woods won his second straight PGA Championship and fifth major title at the PGA event in 2000, shooting a score of -18 and beating Rob May in a three-hole playoff.

Woods led the tournament from the first round to the last and picked up the 2000 PGA Championship on the way to winning the 'Tiger Slam' after securing three of the four majors in the same year, and the 2001 Masters.

Woods moved to 12-0 in major tournaments where he led or shared the lead after 54 holes, beating the rest of the field by five strokes and finishing on -18.

Woods became the first player to win the PGA Championship twice at the same course (Medinah) and winning two major championships in successive years.

Jason Day won his first major title at the PGA Championship in 2015, becoming the first player in major history to shoot 20 under par.

Day shot a four-round score of 268 (68, 66, 67, 66), fending off Jordan Spieth by three shots, who was looking to win three major titles in one year.
