The drama went down to the very last hole in the LPGA's final event of 2017. Here's how things ended up at the CME Group Tour Championship, where a surprising miss from Lexi Thompson opened the door for Ariya Jutanugarn to win in dramatic fashion:
Leaderboard: Ariya Jutanugarn (-15), Lexi Thompson (-14), Jessica Korda (-14), Pernilla Lindberg (-13), Eun-Hee Ji (-13)
What it means: There were scenarios aplenty entering the final round, with nearly every season-long accolade still hanging in the balance. Thompson appeared set to take them all as she sized up a 2-foot par putt on the final hole - a stroke that looked like it would take her to world No. 1 for the first time. Instead, the putt barely touched the hole and allowed Jutanugarn to rally to victory with birdies on the closing two holes. Thompson still took home $1 million for winning the season-long Race to the CME Globe, as it was a reverse scenario from last year when Jutanugarn won the $1 million but not the final tournament.
Round of the day: Sei Young Kim made the day's biggest charge, turning in a 6-under 66 to close the week in a share of 11th at 10 under. Kim made eight birdies during the final round, including five over her first eight holes en route to her lowest round of the week while erasing a third-round 75.
Best of the rest: Jutanugarn seemed like an afterthought as the tournament was winding down, but she kept her hopes alive with an 18-foot birdie on No. 17 and then capitalized on Thompson's mistake with a clutch birdie on the difficult final hole. It capped off a final-round 67 for the Thai who now ends what has been a tumultuous season with a smile on her face.
Biggest disappointment: Thompson faced heartbreak after the penalty-shrouded ANA Inspiration, and she again must handle a setback after essentially missing a tap-in with everything on the line. Thompson can enjoy a $1 million consolation prize along with the Vare Trophy, but a tournament win would have clinched Player of the Year honors as well as her first-ever trip to world No. 1. Instead, she now has the entire off-season to think about how things went awry from close range.
Shot of the day: There were only three birdies on No. 18 during the final round before Jutanugarn laced one down the fairway and hit a deft approach to 15 feet. The subsequent putt found the target and gave her win No. 7 on her young LPGA career.
