The 2020 PGA Championship tees off Thursday at San Francisco's TPC Harding Park, which is hosting its first-ever major.

Why it matters: It's the first major in more than a year — and the first of seven majors in the next 12 months. Though there won't be any fans in attendance, the excitement is palpable.

• "We are about to enter, starting Thursday, the greatest stretch of golf in the history of the game," sportscaster Jim Nantz said.

The state of play: Naturally, the field is loaded, featuring 95 of the world's top 100 golfers.

• Brooks Koepka is going for his third straight PGA Championship title, a feat never accomplished since it switched to stroke play in 1958 (Walter Hagen won four in a row in match play during the 1920s).
• Tiger Woods appears set to make a rare putter switch, using his backup Scotty Cameron instead of the famous Newport-2 he used to win 14 of his 15 majors.
• Justin Thomas is currently ranked No. 1 in the world and is coming off an impressive World Golf Championship win. He won the 2017 PGA Championship and finished tied for sixth in 2018 (didn't play in 2019).
• Bryson DeChambeau is absolutely crushing the ball off the tee. That makes him a favorite, as Harding Park's thick rough favors big bombers because it's far easier hit short irons out of it than it is to hit long irons.

TPC Harding Park is a city-owned course, with roughly 65,000 rounds played there each year, some for as little as $50.

• This makes it arguably "the most unpretentious site ever to host a major," said Phil Ginsburg, general manager of San Francisco's Recreation and Parks Department.
• "One side is lined by dorms and apartment buildings across a busy boulevard, fenced by chain-link," writes the New York Times' John Branch.
• "There is no chateaux-style clubhouse, and amid the cart-pulling, bag-carrying golfers are joggers and dog walkers."
• "But the course is blessed with a classic layout — tight fairways lined by majestic cypress trees, its front nine folded inside a back nine that unwinds alongside Lake Merced."
