The 2021 PGA Tour calendar year was one for the ages. Now that the golf world will be resting until the Sentry Tournament of Champions in the new year, it's a good time to look back at the year that was.

Everyone loves a good underdog, a longshot, a dark horse. There are always a few winners that nobody saw coming each PGA Tour season, so let's reflect on which ones were the biggest from a betting standpoint in 2021.

PGA Tour Biggest Upsets in 2021

Cameron Champ - 3M Open (100/1)

I will not confirm nor deny that I wrote this article solely so I could brag about hitting a 100/1 winner in golf this year. Cameron Champ will forever hold a special place in my heart after cashing big for me at the 3M Open this year.

Champ outdrove the rest of the field, and he had the best tournament of his career with his putter. It was his third win on Tour and his first since the 2019 Safeway Open.

Cameron Davis - Rocket Mortgage Classic (120/1)

When you think of the top Australian golfers in the world, Cameron Davis likely isn't the name that's going to pop in your head. Davis got his first win of his professional career at the Rocket Mortgage Classic in July, and he cashed in big for anyone who wagered on him.

He defeated Troy Merritt and Joaquin Niemann in a playoff to secure the victory.

Stewart Cink - RBC Heritage (150/1)

Stewart Cink captured two wins on PGA Tour in the 2021 season, but the first came at the Safeway Open which took place in the 2020 calendar year so it doesn't qualify for this list. Despite already winning on Tour during the same season, he was listed at 150/1 to win the RBC Heritage.

The 48-year old was the oldest golfer to win on the PGA Tour in the 2021 season, but that title was eventually usurped by someone else who's still to come on this list.

Kyoung-Hoon Lee - AT&T Byron Nelson (200/1)

Kyong-Hoon Lee, or better known as KH Lee, captured his first PGA Tour victory at the AT&T Byron Nelson this season. In hindsight, we should have saw it coming after Lee looked impressive at the Waste Management Phoenix Open just a few months earlier, finishing in second place.

Anyone who had the foresight to sprinkle some money on the South Korean golfer, walked away from the tournament quite a bit richer.

Phil Mickelson - PGA Championship (250/1)

I don't care what anyone else says, Phil Mickelson winning the PGA Championship this year is one of the most impressive feats in professional sports during my lifetime. He became the oldest golfer to win a major tournament at 50 years old, which is even more mind-blowing when you consider how the sport has evolved.

Golf is now a young mans game, with the best golfers in the world having yet to reach the age of 30. Mickelson went head-to-head with Brooks Koepka in the final round of the tournament, and straight up beat the guy who has won four majors dating back to 2017.

I don't know if it makes it more or less impressive, but Mickelson was a complete non-factor on Tour both before the tournament, and after. He was playing some of the worst golf of his long-tenured career, but he put everything together for what will go down as one of the most historic performances in golf history, especially from a betting perspective.
