Why the 'Perfect Game' Is a Bad Omen for Teams

On June 13, San Francisco’s Matt Cain pitched the 22nd perfect game in Major League Baseball history. Since that 10-0 win for the Giants, the team has won only four of their next 10 games.

Before you respond, “So what?” consider this: In the 10 games after the White Sox's Philip Humber pitched his perfect game on April 21 of this year, the White Sox won only four and lost six.

You might think that after a big, monumental game in a team’s history (like a perfect game), the team would then venture into a winning streak of five or six games, or win eight of their next 10. That certainly has not been the case.

To quantify this theory, we looked at the 22 perfect games and how well each team did after this historic game.

(Note: Because Mike Witt‘s September 30, 1984, perfect game came on the last day of the season, and Don Larsen’s October 8, 1956, perfecto happened in the World Series, we did not include those two perfect games in this analysis.)

In looking at 20 of the 22 perfect games pitched in MLB history and how well those teams performed in the next 10 games after their perfect game, we discover that:

  • The teams whose pitcher threw a perfect game compiled a record of 88-106-1, a .454 winning percentage, in the 10 games after the perfect game (for Addie Joss‘ October 2, 1908, perfect game, the Indians played five more games to end the season).
  • Only seven of the 20 teams had a winning record (6-4 or better) after the perfect game.
  • Of the last six perfect games (all since 2000), each of the teams whose pitcher threw a perfect game finished under .500 in their next 10 games.

 

Here’s a look at the teams that had the best post-perfect game 10-game records:

Here are the three teams with the worst records in the 10 games following a perfect game:

2-8Oakland AthleticsCatfish HunterMay 8, 1968
2-8Worcester WorcestersLee RichmondJune 12, 1880

 

Teams that were the victim of a perfect game have actually fared better in the 10 games following the perfect game. Teams that were the victims of a perfect game won 100 and lost 94 in the 10 games (a .515 winning percentage) after the perfect game (the Chicago White Sox four games to finish the season after Joss’ perfect game).

Nine of these 20 teams went on to have a winning record in the next 10 games following the perfecto tossed against them. Most recently, the Tampa Bay Rays went 8-2 after being on the losing end of Dallas Braden’s May 9, 2010 perfect game.

Of the two teams this year who were victim to a perfect game, Seattle and Houston, both went 4-6 after that historic game.
