Ah, Leap Day.

Every four years, we are “blessed” with an extra day. Not an extra weekend day or an extra summer day, but a completely regular day at the end of February, one of the worst months.

In honor of our extra day, let’s look back on some of the best extra-time events in the history of sports.

Tiger Woods vs. Rocco Mediate, 2008 U.S. Open Playoff

Surprisingly enough, our list begins with a journey into the world of golf. While Woods was still the world’s most dominant golfer in the summer of 2008, the gap was starting to close. Injuries had taken their toll and the gap was narrowing. Woods had knee surgery just two months earlier and barely practiced the week of the U.S. Open, his first event back.

By Sunday’s final at the notoriously tough Torrey Pines, Woods held a two-stroke lead over Rocco Mediate, who came into the weekend ranked No. 158 in the world. Mediate finished the final round -1, as did Woods. An 18-hole Monday playoff awaited both men. But then, for the first time since 1994, 18 holes of the playoff wasn’t enough. Woods and Mediate both finished deadlocked at even par. Mediate bogeyed on the first playoff hole to give Woods the win.

Woods missed the rest of the PGA season to recover from injuries, and he wouldn’t win another major until the 2019 Masters.

Syracuse vs. UConn – 2009 Big East Tournament

While the Big East is still around and still thriving (four NCAA Championships since 2016 as a conference), the “new” Big East is lacking the old one’s big-time rivalries — like this one. The UConn-Syracuse rivalry dates back to 1956, but their 2009 showdown in the Big East Tournament quarterfinal is the most famous, by far.

Unsurprisingly, the game was back and forth throughout, with Connecticut tying the game at 71 with just one second to play and Syracuse’s Eric Devendorf hitting what appeared to be a buzzer-beating three-pointer before it was waved off, leading to overtime. Then another. Then another. By the time Syracuse came away with a 127-117 win, the teams had played a total of six overtimes in a game spanning three hours and 46 minutes.

United States vs. Canada – 2010 Winter Olympics

Eight years after Canada defeated the United States to win the gold medal in ice hockey at the 2002 Olympics in Salt Lake City, the USA had a chance to return the favor in Vancouver. The USA added fuel to the fire by picking up a 5-3 victory over Canada in group play. The Americans cruised to the gold medal game where they were once again awaited by Canada.

A nail-biter throughout, the USA forced overtime with just 25 seconds to play when Zach Parise found the back of the net, but Sidney Crosby netted the game-winning goal for Canada seven minutes into the sudden-death period to capture the gold medal with a 3-2 win.

Chicago Cubs vs. Cleveland Indians – 2016 World Series, Game 7

The stakes have arguably never been higher in a World Series game. The Cubs hadn’t won a World Series since 1908 and Cleveland hasn’t since 1948. Both teams had been close to capturing the title through the years but fell short in heartbreaking ways. By the time Game 7 rolled around, fans of both teams had been through the ringer, with Cleveland going up 3-1 in the series before the Cubs stormed back with two wins to force the finale.

The game itself was everything one could want in a baseball game. The Cubs got out to an early lead before Cleveland outfielder Rajai Davis hit an unlikely game-tying home run off flamethrower Aroldis Chapman. The teams remained tied through nine innings, when a storm system surged through Cleveland resulting in a 17-minute rain delay.

The delay turned out to be just what the Cubs needed to refocus, as they scored two runs in the top of the 10th and fought off an attempted rally from Cleveland in the bottom half of the inning to come away with an 8-7 victory to clinch the championship.

New England Patriots vs. Atlanta Falcons – Super Bowl LI

The first Super Bowl to ever go into overtime also featured one of the greatest choke jobs in sports history. The Atlanta Falcons led 28-3 late in the third quarter and entered the fourth quarter in the driver’s seat, holding a commanding 28-9 lead. They were just 15 minutes from capturing their first Super Bowl in franchise history.

The Falcons took their foot off the gas, seemingly forgetting they had a big lead and passing the ball instead of letting the clock slowly bleed with runs. New England stormed back to tie the game at 28, won the coin toss in overtime, and scored a touchdown on their first drive to capture their fifth Super Bowl.
