Bryson DeChambeau captured his eighth career PGA Tour victory Sunday at the Arnold Palmer Invitational. Here’s everything you need to know from the very difficult final round at Bay Hill Club and Lodge:

Leaderboard: DeChambeau (-11), Lee Westwood (-10), Corey Conners (-8), Jordan Spieth (-6), Andrew Putnam (-6), Richy Werenski (-6)

What it means: In addition to his U.S. Open triumph, DeChambeau has now won Jack Nicklaus’ tournament (2018 Memorial) and Arnold Palmer’s. He’s also proven to be one of game’s best – if not the best – tough-course players in the world. Bay Hill was a beast on Sunday, with a field scoring average more than 4.6 shots higher than in Round 3. Add this to his dominant performance at Winged Foot and Bryson’s brawn seems best suited for the most strenuous tests.

How it happened: A four-man tournament was reduced to two front-runners when Westwood birdied the par-5 12^th to tie DeChambeau. At 11 under, the final twosome was two shots clear of the field. They remained deadlocked until Westwood three-putted from 38 feet at the 14^th. Conners did eagle the par-5 16^th to briefly get back within one, but promptly bogeyed the 17^th. Meanwhile, DeChambeau parred No. 16 and stayed one up on Westwood, who missed a 7-footer for birdie. The two parred No. 17 and when Westwood rolled in a 7-footer for par on 18, it meant DeChambeau had to make his from 5 feet for the win. After backing off once, he emphatically drilled it. 

Round of the day: DeChambeau's 1-under 71. The field averaged more than 75.5 shots in the final round and 71 was the lowest score of the day (shot by three players). After a bogey at the first hole, DeChambeau didn't drop a shot the rest of the day, parring his final 12 holes.

Shot of the day: There was DeChambeau’s 377-yard tee shot on the par-5 sixth.

There was also DeChambeau’s 50-foot par save at the par-4 11th.

But the Shot of the Day was the winner, the 5-footer for par at the last.

Biggest disappointment, Part I: Spieth. With birdies at Nos. 4 and 6, Spieth was a co-leader. But there were no more red numbers. He bogeyed the eighth hole, made a string of pars, and then bogeyed Nos. 15, 17 and 18. It added up to a 3-over 75 and a T-4.

Biggest disappointment, Part II: Rory McIlroy. The past champion was four back to start the day and never gave himself a chance. He bogeyed the second hole and put two balls in the water off the tee at No. 6. McIlroy finished with 76 but still managed a top-10 when Keegan Bradley, who went 64-78 over the weekend, bogeyed the final hole.

Quote of the day: "I don't even know what to say about winning Mr. Palmer's tournament. It's going to make me cry." – DeChambeau
