She nevertheless birdied three of the last six holes to force the playoff, but couldn't match Ryu's playoff birdie.
On Sunday afternoon, a viewer emailed officials with a discrepancy the viewer had noticed while watching the broadcast of the tournament: Thompson had not properly placed her ball in the same spot while putting during the third round of the tournament the day before, off by one inch. "I seem to have more fun each year when I play this golf course". "And to be able to drive down Magnolia Lane with a green jacket in the vehicle and to come back and to be announced on the tee as the defending champion. words can't really quite describe the feeling". "I didn't even realize I did that".
Incredibly, Thompson still almost managed a win with three birdies on the last six holes before missing a 20-foot eagle putt and handing the win to South Korean So Yeon Ryu - who is expected to now move up to 2 in the world.
The controversy distracted from a superb final round, during which Thompson carded seven birdies, including one on the 13th hole immediately after being informed of the penalty.
That ended a rousing final stretch that saw Thompson, 22, lose a three-stroke lead when penalized for an improper replacement of a ball - from Saturday - but rally for a final-round 67.
Back in December, when Spieth returned to Augusta National for the first time since that fateful day to play a round with friends, he was thinking about what happened on the last day of the Masters.
Lucy Li, the 14-year-old amateur who played the opening round with Michelle Wie, who played here as a 13-year-old, shot an even-par 72 on Sunday and tied for 70th with a four-day total of 295.
Gael Clichy backs under-fire Arsenal boss Arsene Wenger
About 1,000 Arsenal fans joined an anti-Wenger march before the game, the biggest such protests against the Frenchman. If we show the same spirit we showed against City [in Sunday's 2-2 draw], we will win football games.
"It's great to have the fan base that I do and they really got me through the whole round", Thompson said. It's a very unfortunate situation. "I was paired with my best friend, Park In-bee today, so I just really wanted to have a really good, strong finish".
"I don't understand how they can allow people to call in, I just find that absurd".
RANCHO MIRAGE Never did the Poppie's Pond leap into feel so anti-climactic. The 2014 ANA Inspiration victor made three birdies on her opening nine and added a birdie on the par-5 11th hole.
Thompson won this tournament in 2014, and she has excelled for four consecutive years at the LPGA's first major of the season.
The first LPGA major of the year has descended into controversy, after a TV viewer alerted officials to an indiscretion by leader Lexi Thompson from the previous round, prompting a four-stroke penalty.
"Whenever an invitation or a request comes my way, I don't want to say I jump at the chance but at the same time, you know, to see the Secret Service, to see the scene, I mean, that's really what I was going for", McIlroy said. "When I go away from technical and toward feel, it's an advantage for me".
