SHEBOYGAN, Wis. (AP) A year of major heartache ended with Jason Day breaking through in a major way Sunday at the PGA Championship.

With at least a share of the 54-hole lead for the third straight major, Day never gave Jordan Spieth or anyone else much of a chance at Whistling Straits. The 27-year Australian shot a 5-under 67 for a three-shot victory and broke Tiger Woods' major record for strokes under par by finishing at 20 under.

In tears before tapping in for par, Day hugged his son and wife and then Spieth, who finished second and moved to No. 1 in the world - ending Rory McIlroy's one-year reign.

Day started the final round with a two-shot lead and no one got any closer than that the entire day. With a three-shot lead on the par-5 16th, Day hit a high draw onto the green, bit his lower lip and swatted longtime coach and caddie Colin Swatton in the arm. That two-putt birdie took him to 20 under, and two pars sealed the victory.

Woods finished at 19 under when he won the 2000 British Open at St. Andrews.

Spieth set a record of his own. By 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. The difference is that Woods won two majors by a combined 23 shots.

PORTLAND, Ore. (AP) - Brooke Henderson won the Cambia Portland Classic by eight strokes to become the third-youngest champion in LPGA Tour history at 17 years, 11 months, 6 days.

The Canadian closed with a 3-under 69 at Columbia Edgewater to finish at 21-under 267, the lowest total since the event went from 54 holes to 72 in 2013.

Lydia Ko set the age record as an amateur in the 2012 Canadian Women's Open at 15 years, 4 months, 2 days. She also won the Canadian event in 2013 at 16, and won four times at 17. Lexi Thompson won the 2011 Navistar LPGA Classic at 16 years, 7 months, 8 days.

Henderson's eight-stroke margin is the largest in the history of the event and the biggest on the LPGA Tour since Jiyah Shin won the 2012 Women's British Open by nine shots.

Henderson also became the first Canadian winner since Lorie Kane in the 2001 Takefuji Classic and joined Laurel Kean as other only Monday qualifiers to win. Kean did it in the 2000 Rail Classic.

Pornanong Phatlum (68), Ha Na Jang (70) and Candie Kung (70) tied for second.

AUTO RACING

BROOKLYN, Mich. (AP) - Matt Kenseth raced to his third NASCAR Sprint Cup victory of the season, winning in convincing fashion Sunday at Michigan International Speedway.

Kenseth, the pole winner, won for the 34th time in his career, leading 146 of 200 laps in the 400-mile race. Joe Gibbs Racing has won five of the last six Cup races.

Kevin Harvick was second, 1.7 seconds behind, and Martin Truex Jr. was third.

Austin Dillon, who was sent to the back at the beginning of the race because of an engine change, managed a fourth-place showing, and Kyle Busch took another step toward wrapping up a spot in the Chase with an 11th-place run in his backup car.

NASCAR used a special high-drag aerodynamic package for this race and last month's even at Indianapolis Motor Speedway. It was supposed to improve passing, but aside from one brief duel at the front between Kenseth and Dillon with about 55 laps left, there was little drama in terms of lead changes.

BASEBALL

IDAHO FALLS, Idaho (AP) - It had been a long day and night for David Denson, in so many ways.

His team had been swept in a doubleheader in the low-level Pioneer League, he didn't have much luck hitting and he'd made a throwing error, too.

Hours earlier, the Milwaukee Brewers minor leaguer had become the first openly gay active player on a team affiliated with Major League Baseball. The news broke in the middle of the second game, after he reached out to the Milwaukee Journal Sentinel.

In June, pitcher Sean Conroy of the Sonoma Stompers of the independent Pacific Association revealed he is gay. The Pacific Association is not affiliated with MLB. Denson's coming out follows similar disclosures of late across sports: Michael Sam (NFL draftee); Jason Collins (NBA); Derrick Gordon and Edward Sarafin (NCAA basketball, football) and Dale Scott (major league umpire).

Several hours before Denson's team played at Idaho Falls on Sunday, the Helena club said the first baseman-outfielder didn't want to do further interviews for a few days.

GYMNASTICS

INDIANAPOLIS (AP) - Sam Mikulak had little trouble picking up his third straight U.S. gymnastics title Sunday, overcoming an early misstep on high bar to dominate a crowded field that will give the Americans a deep roster heading into the world championships in October.

Mikulak posted a two-round score of 183.650, a whopping 4.35 points ahead of Donnell Whittenburg in the gymnastics equivalent of a blowout. A rejuvenated Chris Brooks took third, followed by Alex Naddour and Marvin Kimble in the final chance to impress the selection committee before world rosters are announced.

The 22-year-old Mikulak's spot was never in doubt as he became the first American since Paul Hamm in 2002-04 to win three consecutive national titles. He will lead the U.S. to Scotland in October as the Americans try to back up the team bronze they won last year.

TENNIS

MONTREAL (AP) - Andy Murray beat top-ranked Novak Djokovic 6-4, 4-6, 6-3 on Sunday in the Rogers Cup for his fourth tournament victory of the year and third title in the Canadian event.

The second-seeded Murray also won the tournament in 2009 and 2010. The Scot ended an eight-match losing streak against Djokovic since the 2013 Wimbledon final.

Murray dedicated the victory to his coach, Amelie Mauresmo, the former women's star who gave birth to a boy Saturday.

Djokovic, the champion in 2007, 2011 and 2012, lost for only the fourth time in 56 matches this year. The Serb failed in his bid to tie the ATP Tour record for consecutive Masters 1000 event titles at five. Djokovic was playing his ninth straight final, a run that included championship victories over Murray this year in the Australian Open and Key Biscayne, Florida.

TORONTO (AP) - Swiss teen Belinda Bencic won the Rogers Cup on Sunday, following her upset of Serena Williams with a 7-6 (5), 6-7 (4), 3-0 victory over an ailing Simona Halep.

The 18-year-old Bencic won her second WTA Tour title after breaking through this summer on grass in England at Eastbourne. She's ranked 20th.

Halep was hampered by a left leg injury, cramps and heat exhaustion and stopped in the third set.
