Thompson on missed putt: 'I don't know what happened there'

Lexi Thompson's lone bogey Sunday at the CME Group Tour Championship cost her more than just a potential playoff with Ariya Jutanugarn.

"It wasn't the way I wanted to end it. I don't know what happened there," Thompson told Randall Mell of the Golf Channel.

Thompson was a two-foot putt away on the 18th green from likely winning LPGA Tour Player of the Year and ascending to world No. 1 for the first time. Her putt, however, lipped out, opening the door for Jutanugarn, who drained a 20-foot birdie putt on the 72nd hole to pass the young American for the win.

"Honestly, I wasn't even thinking about (the awards)," added Thompson. "Maybe just a little bit of adrenaline. I guess it's just golf. Crazy things happen like that. I'll move on."

The 22-year-old did take home $1 million for winning the year-long Race to the CME Globe, and won the Vare Trophy for the lowest scoring average, but watched Sung Hyun Park and So Yeon Ryu share Player of the Year honors.

Earlier in the season, Thompson suffered a heartbreaking loss at the ANA Inspiration, when she incurred a four-stroke penalty in the middle of her final round.
