1986: Buckner’s Blunder Breaks Boston’s Heart (Game 6)

One out away from breaking the curse, the Red Sox watched their dreams of winning their first World Series since 1918 dribble through Bill Buckner’s legs. Vin Scully’s haunting call—”Behind the bag! It gets through Buckner!”—became the soundtrack of New England nightmares. Some fans blamed the situation on Rich Gedman’s not getting a glove on the passed ball that allowed the tying run. After losing Game 7 a couple of days later, the Sox would wait another 18 years before finally exorcising their demons and putting the ghost of the Bambino to rest.
2001: Yankees’ Dynasty Dies in the Desert (Game 7)

In the shadow of 9/11, the Yankees were destiny’s team until Luis Gonzalez’s broken-bat blooper off Mariano Rivera shattered the fairy tale. A city desperate for healing watched its seemingly invincible closer finally prove human. The dynasty that defined the late ’90s ended on a dying quail into center field.
1975: Carlton Fisk’s Homer Only Delayed the Heartbreak (Game 7)

After Fisk’s iconic wave-it-fair homer in Game 6, Boston’s destiny seemed certain. But Joe Morgan’s ninth-inning bloop single the next night turned the greatest game ever played into just another chapter of Red Sox heartache. The Big Red Machine crushed Boston’s storybook ending.
1960: Yankees Score 55 Runs, Still Lose to Pirates’ Magic

The mighty Yankees outscored Pittsburgh 55-27 and lost the Series on Bill Mazeroski’s walk-off homer, though Bronx Bomber fans of a certain age will never forget this image of Yogi Berra peeling away as the ball soared overhead. Casey Stengel was fired despite his team winning three games by scores of 16-3, 10-0, and 12-0. This was certainly one of the game’s oddities.
1991: Lonnie Smith’s Baserunning Gaffe Costs Atlanta Glory

People make mistakes all the time. Very few do it in front of millions of viewers. In a scoreless Game 7, Smith got deked by Chuck Knoblauch and missed a chance to score on Terry Pendleton’s double. Jack Morris pitched all 10 innings for Minnesota, while Atlanta’s missed opportunity kept it from completing its “Worst to First” season with a World Series trophy.
1985: Don Denkinger’s Call Changes Kansas City History

Talk about an error in judgment that will stand the test of time. The Cardinals were one out away when Jorge Orta was called safe on a play where replays showed he was clearly out. St. Louis unraveled, and the missed call became the Series’ defining moment. Cardinal fans still wince at Denkinger’s name decades later.
1988: Mighty A’s Stunned by Gibson’s Impossible Homer

The 104-win A’s watched helplessly as Kirk Gibson, barely able to walk, launched a Dennis Eckersley pitch into history. Jack Buck’s “I don’t believe what I just saw!” captured the moment perfectly. Oakland’s powerhouse team never recovered from the shock.
1967: Cardinals Turn Boston’s Impossible Dream Into Nightmare

Carl Yastrzemski was the last hitter to achieve baseball’s Triple Crown. Jim Lonborg won 22 games and helped propel Boston into the World Series in a season known as “The Impossible Dream.” Bob Gibson and the St. Louis Cardinals played against Freddy Krueger and ultimately won the Series in seven games.
1968: McLain and Tigers Outshine Gibson

Gibson posted a miraculous 1.12 ERA that season, but Mickey Lolich outdueled him in Game 7. Detroit also had Denny McLain (pictured as No. 17), who was the last pitcher to win over 30 games in a season. The Cardinals’ ace had won seven straight World Series starts before the Tigers ended his October invincibility. A perfect season ended imperfectly.
1990: Reds Stun Goliath A’s In Sweep.

Oakland looked like it was destined to repeat after they had won the 1989 World Series against the San Francisco Giants in the “Earthquake Series.” Jose Canseco and Mark McGwire continued their run as the Bash Brothers. Dave Stewart and Bob Welch both won over 20 games, with Welch winning 27. After steamrolling the Boston Red Sox in the Championship Series, it was Oakland’s turn to get punched. Eric Davis set the tone with a homer off Stewart, and the A’s were then swept. Now the team is exploring a move to Las Vegas, and their fans are still wondering, “What happened?”
