2020 PGA Championship

The 2020 PGA Championship was the 102nd edition of the PGA Championship, and the first of golf's three major championships played in 2020. It was held August 6–9 at TPC Harding Park in San Francisco, California, having originally been scheduled for May 14–17. Due to the COVID-19 pandemic, it was the first major played in over a year, and had no spectators in attendance. It was the first major held at Harding Park, which had previously hosted World Golf Championship events in 2005 and 2015, and the 2009 Presidents Cup.

In his PGA Championship debut, and second major appearance, Collin Morikawa won by two strokes ahead of runners-up Paul Casey and Dustin Johnson. Multiple players competed for the lead in the final round, and it was only after a birdie on the 14th, and an eagle on the short par-4 16th, that Morikawa was able to break away from the field. At age 23, he became the third youngest PGA Championship winner since World War II, behind Rory McIlroy and Jack Nicklaus, and rose from 12th to 5th in the Official World Golf Ranking. Morikawa also set a new PGA Championship scoring record for the final 36 holes with 129 strokes (65-64).

Casey's second place was his best finish in his 64 career major starts, the most by any player since 2002 without a victory. Johnson repeated his second place standing from the previous edition. Brooks Koepka entered the tournament as two-time defending champion and looking to become the second player after Walter Hagen to win three straight titles; tied for fourth place after round three, and only two shots behind the leader, he was expected to challenge for the title, but struggled in the final round and finished in a tie for 29th place. The top three players in the world rankings heading into the tournament were Justin Thomas (winner of a WGC event the previous week), Jon Rahm, and Rory McIlroy, but none of them were able to contend for the title.

This was the first major championship held at Harding Park. It was also the first PGA Championship in the Western United States since 1998 at Sahalee Country Club near Seattle, Washington, and the first in California since 1995 at Riviera Country Club in Los Angeles.

Harding Park had previously held the 2015 WGC-Match Play Championship, won by Rory McIlroy, the 2009 Presidents Cup won by the United States, and the 2005 WGC-American Express Championship won by Tiger Woods.

Before the COVID-19 pandemic up to 40,000 spectators per day had been expected to attend.

The PGA Championship field is regarded as one of the strongest in professional golf, with the highest strength of field rating of the year according to the Official World Golf Ranking, including almost all of the top one hundred players in the rankings. A number of qualification criteria were used to determine the field, including past PGA champions, recent major winners, top finishers in the 2019 PGA Championship, Ryder Cup players, tournament and leading money winners on the PGA Tour, and twenty PGA club or teaching professionals. The PGA of America also issue invitations to players outside of these criteria, which is generally seen to include the top one hundred in the world rankings.

Seventeen former PGA champions were in the field, including two-time defending champion Brooks Koepka, who was aiming to become the second player to win three in a row after Walter Hagen who won four in a row from 1924 to 1927, world number one Justin Thomas, number three Rory McIlroy, and four-time champion Tiger Woods. Among the former champions not to play were Yang Yong-eun, Pádraig Harrington, John Daly and Vijay Singh, who withdrew due to various concerns about the COVID-19 pandemic, health and injury. Francesco Molinari, winner of the 2018 Open Championship, also withdrew.
