Here are five of the most memorable rules and scorecard mistakes at the Masters Tournament

Last April, Anna Davis became the youngest player to capture the Augusta National Women’s Amateur.

This year, her tournament was derailed on the opening hole at Champions Retreat. The California teen lifted her ball twice from the rough, incurred a four-stroke penalty, and missed the cut. Davis called it, “a learning experience.”

She's not the only player to be caught up in the rules at Augusta National, though. Here are five notable penalties from the Masters Tournament.

Thursday 1953: Sam Snead sunk

Paired with defending champion Sam Snead, Byron Nelson put the Slammer down for par on the final hole, when in reality it was a three. Snead signed the card, then departed to the Par 3 Course for afternoon fishing. After reeling in two large mouths at Ike’s Pond, Snead showered and changed into a dark blue suit before entering the clubhouse for dinner. Inside he was greeted by Furman Bisher, the famed scribe for the Atlanta Constitution, who desired a quote on the scoring blunder.

“I don’t know what you’re talking about,” Snead said.

Bisher had broken the news. Sam’s opening round 70 was now 71, but it wasn’t just the scorecard that changed – it was Snead’s head. A day later, the Virginian remained focused on Byron’s error. “Why do these things always happen to me?” Snead muttered to no one in particular.

Denny Shute, winner of the 1933 British Open and two-time PGA champ, rationalized with Snead, saying, “Oh, well. Go out and birdie No. 1 and make up for it today.”

“I can birdie No. 1 but I’ll never get that stroke back,” said Snead, ignoring the encouragement. “It’s gone forever.”

Snead crashed to a Friday 75 and was out of contention. The defending champion tied for 16th, the only time from 1949 to 1957 where he didn’t place in the top eight.

Thursday 1960: A costly practice putt from Dow Finsterwald

Dow Finsterwald carded 69 to open the 1960 Masters and was nearly midway through his second round when he dropped a ball on No. 8 green. After finishing the hole, Finsterwald, who died in November at age 93, prepared to hit a practice putt when playing partner Billy Casper alerted him to not strike the ball.

"Billy told me that hitting a practice putt was against the rules at Augusta," Finsterwald recalled in 2018. "But I had already done it (on No. 5) during my opening round."

After his second-round 70, Finsterwald would have been alone atop the leaderboard, but the rules committee retroactively changed his first-round score from 69 to 71. Instead of being 5 under, Finsterwald entered the weekend a stroke behind Palmer.

"It doesn't bother me," Finsterwald said, when looking back. "To be honest, I was lucky to not be disqualified for signing an incorrect scorecard after the first round.”

Finsterwald finished two behind Arnie’s winning score of 282.

Friday 2013: An amateur's rookie mistake

A decade ago, Tianlang Guan, the 14-year-old Chinese amateur, was penalized a stroke for slow play at the par-4 17th hole during the second round.

Guan, Ben Crenshaw and Matteo Manassero were put on the clock on the 12th hole. At No. 17, Guan hit his drive before being assessed a slow-play penalty on his second shot.

"I think our group was warned once that we were out of position," Crenshaw said after the round. "This isn't going to end up pretty, I don't think. I'm sick. He's 14 years old. When you get the wind blowing out here, believe me you're going to change your mind. I'm sorry, I'm a player. It's not easy to get around this golf course.”

Despite the penalty, Guan made the cut and was low amateur that year.

Friday 2013: Tiger's infamous drop on No. 15

Tiger Woods was charging: A first-nine 33, and needed a birdie at No. 15 to tie the lead. Then, it happened.

Tiger’s approach collided with the flagstick, raced into the pond, and needed six total strokes to finish the hole.

Bogey.

Or so we thought.

It wasn’t until late Friday evening that word began to circulate about Tiger’s drop. According to rule 26-1, Woods had three options:

1. Play from the hole's designated drop area.

2. Drop on a line from where the ball last crossed the hazard, as far back as he wanted.

3. Drop as nearly as possible to the original spot of his third shot, no closer to the hole.

Woods said he didn't like the grain of the grass at the drop area and elected to take Option 3. But by his own admission, he dropped two yards from the proper spot, thus not nearest to the original location.

Woods would avoid disqualification but was assessed a two-stroke penalty. He lost to Adam Scott by four.

Sunday 1968: Roberto De Vicenzo's playoff hopes smashed

Roberto De Vicenzo was celebrating his 45th birthday that Sunday, as galleries serenaded him around the course.

It quickly went sour.

“I play golf all over the world for 30 years, and now all I can think of is what a stupid I am to be wrong in this wonderful tournament," De Vicenzo said afterward. "Never have I ever done such a thing.”

The Argentinian carded 65, finished at 11-under total, and was poised for a playoff with Bob Goalby. But when keeping De Vicenzo’s card, playing partner Tommy Aaron had marked him for 4 instead of 3 on the 17th hole.

Roberto signed the card.

After Goalby finished, the verdict came from Hord Hardin, the chairman of the Masters rules committee:

"Under the rules of golf, (De Vicenzo) will be charged with a 66, which does not leave him in a tie with Bob Goalby, who is 11 under par. He is second, 10 under par."
