Si Woo Kim braved steady winds at TPC Sawgrass on Sunday to become the youngest Players Championship winner in history.

Despite enduring a run of poor form entering the week, the 21-year-old looked poised beyond his years while capturing the season's so-called "fifth major."

Here are our Players Championship winners and losers:

Winners

Si Woo Kim — Not only did Kim win the biggest event of his career — his first PGA Tour win came last year at the Wyndham Championship — he also earned a five-year Tour exemption and a three-year major championship exemption.

Kim fired a bogey-free round Sunday in tough conditions to outlast a packed leaderboard filled with hungry players seeking career-changing wins. With a new silky-smooth swing teamed with a crafty short game, Kim could be a force on the PGA Tour for years to come.

Ian Poulter — What a whirlwind 2017 has been for the mercurial Englishman. Less than a month ago, Poulter was fighting for his Tour card. He appeared to come up short, which would have forced him to rely on sponsor's exemptions the rest of the year. But a points shift earned Poulter his card, and he took advantage of his opportunity this week.

Poulter is a few years removed from his best form. Once a Ryder Cup stalwart and thorn in U.S. players' sides, Poulter has been trying to keep up with the new generation. Poulter once said it would be him and Tiger Woods against everyone. He never reached those heights, but he has been an underrated, under-appreciated player throughout his career.

Adam Scott — Rarely talked about among the game's best players, Scott, who was the previous youngest Players champion, finished tied for sixth at 5 under after shooting a bogey-free 4-under 32 on the back nine Sunday.

Scott became the first Australian to win the Masters in 2013, and he has been a consistent presence in the top 15 of the world rankings over the past decade. Though his putting always runs hot and cold, Scott has always had one of the most sought after swings in golf.

Losers

The world's top 10 players — Scott barely missed the cut, entering the week at No. 11. The ten players ahead of him struggled this week. Dustin Johnson, with a T-12, was the best among the game's elite this week. Just three (Johnson, Henrik Stenson and Hideki Matsuyama) of the top 10 players in the world finished in the top 25.

The leaderboard was desperately lacking star power, and guys like Jason Day, Rory McIlroy, Rickie Fowler and Jordan Spieth, who missed the cut, failed to produce. Sergio Garcia had a chance to win after starting the final round just four shots back, but he shot a 6-over 78 Sunday, sliding back into a tie for 30th.

J.B. Holmes — Not to kick a player when he's down, but Holmes completely dropped the ball Sunday. Despite starting the final round tied for the lead with Kyle Stanley, a 29-year-old who had not won since 2012, Holmes shot a 12-over 84 Sunday to fall outside the top 40.

Holmes hit two balls in the water on 17, which started a quintuple-bogey, double-bogey finish. 

The Players Championship — Is it a major, is it just a really big event, or is it a separate entity that doesn't fit into a specific category? This question has festered and swirled in a confusing mass over the years. Fans seem to think it is like a major; players don't always seem quite as certain. 

Phil Mickelson, who won the event in 2007, didn't even show up for a practice round before the tournament started. Do you think he does that before a major? No, he does not.

TPC Sawgrass is a phenomenal and exciting course, especially with the change to the now driveable par-4 12th hole, but this event needs a locked-in identity.
