Jason Day shows major mettle and wins PGA Championship (Yahoo Sports)

1(AP) -- Given a third straight chance to finally win a major, Jason Day promised a fight to the finish in the PGA Championship.
2Turns out the biggest fight was to hold back the tears.
3Worried that this year might turn out to be a major failure, Day never gave Jordan Spieth or anyone else a chance Sunday.
4He delivered a record-setting performance at Whistling Straits that brought him a major championship he started to wonder might never happen.
5Day was in tears before he even tapped in for par and a 5-under 67 for a three-shot victory.
6He sobbed on the shoulder of Colin Swatton, his caddie and longtime coach who rescued Day as a 12-year-old struggling to overcome the death of his father.
7And then came high praise from Spieth in the scoring trailer when golf's new No.
8''I didn't expect I was going to cry,'' Day said.
9''A lot of emotion has come out because I've been so close so many times and fallen short.
10To be able to play the way I did today, especially with Jordan in my group, I could tell that he was the favorite.
11Three shots ahead with three holes to play on a course with trouble everywhere, Day blasted a drive down the fairway on the par-5 16th and hit a towering 4-iron into 20 feet.
12He bit his lower lip, swatted his caddie on the arm, knowing his work was almost done.
13The two-putt birdie put him at 20-under par, and two closing pars gave him the record to par in majors, breaking by one shot the 19 under of Tiger Woods at St. Andrews in the 2000 British Open.
14Day finished at 20-under 268, not knowing until it was over that it was a record.
15What really mattered was that shiny Wanamaker Trophy at his side.
16He shared the 54-hole lead at the U.S. Open and the British Open and had to watch someone else celebrate.
17''Not being able to finish, it would have been tough for me mentally to really kind of come back from that,'' Day said.
18''It felt like I was mentally and physically grinding it out as hard as I could,'' he said.
19Spieth gave it his best shot, but even the Masters and U.S. Open champion could tell what he was up against the way the 27-year-old Australian powered one drive after another and didn't let anyone closer than the two-shot lead with which he started the final round.
20''He played like he'd won seven or eight majors,'' Spieth said.
21''He took it back.
22He wailed it.
23Spieth has the greatest consolation possible.
24With his runner-up finish, he replaced Rory McIlroy at No.
251 in the world.
26''This is as easy a loss as I've ever had because I felt that I not only couldn't do much about it as the round went on, I also accomplished one of my lifelong goals in the sport of golf.
27I'll always be a No.
28Spieth set a record of his own.
29By closing with a 68, he set a record by playing the four majors in 54-under par, breaking by one the mark that Woods set in 2000.
30The difference is that Woods won two majors by a combined 23 shots.
31That also speaks to the depth of golf in this generation, and Day is the latest example.
32He moved to No.
333 in the world, meaning the top three in the world are all under 27 and have combined to win five of the last six majors.
34''As long as I am healthy, I feel like I'm going to be there a long time,'' Day said.
35''I still want to accomplish that No.
361 goal of mine, which is to be the best player in the world.
37Branden Grace of South Africa had another mistake on the back nine in a major that cost him.
38Grace was tied for the lead at the U.S. Open when he hit his tee shot on the railroad tracks and out-of-bounds at Chambers Bay.
39This time, he was two shots behind when he went long of the 10th green and made double bogey.
40He closed with a 69 and finished third, five shots behind.
41Justin Rose got within two shots until making a double bogey for the third straight day.
42He closed with a 70 and finished fourth.
43Day faced enormous pressure of having a lead for the first time going into the final round, trying to avoid becoming the first player since the PGA Championship went to stroke play in 1958 to have at least a share of the 54-hole lead in three straight majors without winning.
44It sure didn't show, even if he felt it every step of the way.
45''I knew today was going to be tough, but I didn't realize how tough it was going to be,'' Day said.
46''I learned a lot about myself, being able to finish the way I did.
