1. Collin Morikawa shot a bogey-free 64 to win the PGA Championship by two strokes over Dustin Johnson and Paul Casey. Morikawa’s closing 36-hole total score of 129 is the lowest by any player to win a major championship in men’s golf history. Morikawa played the last 22 holes of the tournament bogey-free and nine-under-par.
2. Morikawa pulled off an unprecedented triple of statistical measures. Collin led the tournament in driving accuracy, approach shot proximity to the hole and strokes gained putting. Since the PGA Tour began tracking the latter two statistics in 2003, Morikawa is the first player to win a tournament while leading each of those categories.
3. Morikawa won the PGA Championship at just 23 years, 6 months, 3 days old – the third-youngest to win it in the stroke play era. The only two players to win at a younger age since the championship switched to that format in 1958 are Rory McIlroy and Jack Nicklaus.
4. It took just 27 professional starts for Collin to win his first major title. Since 1970, only two players have won their first major with fewer professional starts preceding it: Tiger Woods (17th start) and Jerry Pate (18th). Morikawa is the first player to win in his PGA Championship debut since Keegan Bradley did it back in 2011.
5. The last two Sunday PGA Championship rounds in California have generated history: in 1995 at Riviera, Steve Elkington fired a closing 64 en route to victory. Sunday, Morikawa matched him, also shooting 64 and winning the Wanamaker Trophy.
6. Dustin Johnson shot 68, but fell to 0-for-4 attempting to convert 54-hole leads into wins in major championships. Johnson is the first player to finish runner-up in the PGA Championship in back-to-back years since Jack Nicklaus in 1963 and 1964. After leading the tournament in strokes gained putting through three rounds, he ranked 33rd in that statistic on Sunday.
7. 43-year-old Paul Casey was trying to become the oldest first-time major champion since Roberto de Vicenzo at the 1967 Open Championship, but finished tied for second. It’s the best finish of Casey’s major career. Casey would have been the oldest major champion from Europe since Ted Ray at the 1920 U.S. Open.
8. Brooks Koepka shot a closing 74 to finish tied for 29th, his worst finish in a major in 749 days. Koepka has now shot 74 in the final round in three of his last four major championships (2019 PGA and 2019 Open Championship). Brooks ranked 74th on Sunday in strokes gained putting out of the 79 players who made the cut.
9. Tony Finau was tied for the lead at one point Sunday, but finished three strokes behind Morikawa. Finau has now finished in the top-five in each of the four major championships. His 31 top-ten finishes on the PGA Tour over the last four seasons is 15 more than any other player without a win in that stretch.
10. The field scoring average Sunday was 69.25, the lowest single day mark in the history of the PGA Championship. The average was a more than full stroke lower than on Saturday (70.42), with the back nine playing especially different. Sunday, the field was 77-under-par on the back nine, 111 strokes less than round three (+34).
