History may well be made Sunday on the Ocean Course at Kiawah Island as Phil Mickelson looks to become the oldest major champion in history. That was the main storyline entering the final round of the 2021 PGA Championship, but Mickelson's journey back to the top was one of only a number of interesting takes entering the final 18 holes at one of the most picturesque courses in the nation.
Brooks Koepka sat just one shot back of Mickelson entering Sunday's final round and even tied him for the lead late Saturday. The four-time major winner aims to capture his third PGA Championship in the last four years and tops the odds board for the second straight day. Louis Oosthuizen is looking for his second major win, and the 42-year-old entered Sunday only two shots back of Lefty, with whom he shared the 36-hole lead entering Saturday.
But the focus is indeed on Mickelson, who is looking to become the 14th man to win six majors and the oldest to ever capture a crown at this level. The Wanamaker Trophy is completely up for grabs Sunday, and Lefty -- with his big, shiny glasses -- is eyeing a return to glory that he has not experienced over the better part of a decade.
Mickelson and Koepka have jockeyed for position through the first handful of holes Sunday, and there's no telling how the round will play out. No matter what transpires, Lefty had the highlight of the major thus far with a tremendous hole out from a sandy area early in his fourth round.
