Chicago Cubs
2003 NLCS
Leading 3-0 and just five outs away from going to their first World Series in 58 years, the Cubs suffered a stroke of bad luck when Steve Bartman grabbed a foul ball off the bat of Luis Castillo before Moises Alou could catch it. Castillo drew a walk, and the Florida Marlins scored eight runs in the inning and went on to win Game 6 and later the series.

Boston Bruins
2010 Eastern Conference Semi-finals
Down 3-0 in games, Philadelphia rallied. Down 3-0 in Game 7, Philadelphia rallied again. Simon Gagne’s power-play goal in the third lifted the Flyers to an improbable 4-3 win over the Bruins. It was humiliating for the Bruins, who became the third team in NHL history to lose a series after winning the first three games. The only other teams to win a series after trailing 3-0 were the 1942 Toronto Maple Leafs, who beat Detroit, and the 1975 New York Islanders, who eliminated Pittsburgh. The other 159 teams that won the first three games in a series all won them.
Memphis
2008 Final Four
Leading 60-51 lead with 2:12 remaining, Memphis missed crucial free throws and watched Kansas hit a pair of three-pointers, including a game-tying dagger by Mario Chalmers with 2.1 seconds left. The Tigers eventually lost 75-68 in overtime.
New York Mets
2007
Having staked a seven-game lead over the Phillies with 17 games remaining, New York seemed like a lock for a second straight division title. But Philadelphia’s mid-September sweep at Shea Stadium would catalyze one of the most monumental September meltdowns in major league history. The Mets dropped six of seven results in a final home stand against teams with losing records to miss the playoffs completely.
Dallas Mavericks
2006 NBA Finals
Dirk Nowitzki and the Dallas Mavericks won the first two games of the 2006 NBA Finals and were ahead 89-76 in Game 3. They ended up losing 98-96 and dropped the next three games too, becoming the 10th NBA team to squander a 2-0 lead in a best-of-seven series.
