A word possibly first coined by the science fiction writer Rudy Rucker. I think he meant by it a person who is into numbers a lot, but doesn't think about their meaning, usefulness, or statistical validity.

Pertaining to the game of baseball, ERA (Earned Run Average) is a statistical measure of the effectiveness of a pitcher. It is computed by the following formula:

ERA = (earned runs allowed)*(9)/(innings pitched)

Obviously, the lower the ERA, the more effective the pitcher, with an ERA of around 1.50 or below being considered excellent.

1) Noun: label for a baseball player who has a horrbile pitching performance
2) Noun: pitcher who is incredibly ineffective and is regarded as the last resort on the team
3) Noun: A pitcher who has a ridiculously high ERA, (in this instance, 297.00, which is attainable by allowing 11 earned runs in ¨÷ of an inning)
4) Noun: A pitcher who has little or no command with his pitches and frequently implodes under pressure

A.K.A. Mariano Rivera, one of the best closers in baseball of all-time. Mariano Rivera is a.k.a Mr. Automatic, because it is a given that when he comes into a game with the lead, the game is over. Mariano Rivera has been a pitcher on the New York Yankees for his whole career, which is now 10 years. Mariano Rivera has pitched in 586 games and 728.1 innings. He has 336 saves and a 2.43 ERA (Earned Run Average).

Arguably the best closer in baseball of all-time. Has been a pitcher on the New York Yankees his whole career, which is now 10 years. He is a.k.a Mr. Automatic because when he comes into a game with a lead, the game is over. He has pitched in 586 games and 728.1 innings. He has 336 saves and a 2.43 ERA (Earned Run Average).

a relief pitcher for the New York Yankees. Born in Panama City, Panama, his rookie season in the Major Leagues was 1995, in which he made a limited number of appearances. In 1996, he served primarily as a set-up man for the closer John Wetteland. During that season, if the Yankees were leading after six innings, they were nearly assured of victory due to the stellar pitching of both relievers. Despite playing in a position that rarely gets respect, Rivera still managed to come in third for the Cy Young voting, behind twenty-game winners Pat Hentgen and teammate Andy Pettitte, respectively.

When Wetteland left the team following that season (in which they won the World Series), Rivera became the Yankees' closer and has remained so ever since. He has been perhaps the most consistent, dependable relief pitcher in the Major Leagues during his tenure as a closer for the Yankees. Rivera has been especially overpowering in the postseason, in which his lifetime earned run average, under 1 run per nine innings pitched, is among the best ever. His contribution to the general success of the Yankees since 1996, including four World Series championships, has been significant. However, in recent years his postseason performance has been a little less consistent, particularly in the 2001 World Series loss to the Arizona Diamondbacks and the infamous 2004 playoff collapse against the Boston Red Sox. His troubles with the Red Sox (although he continues to dominate against other teams) h...

The best young pitcher in baseball, currently 4-0 with a 1.37 earned run average. Recently optioned to Triple-A Salt Lake because Bill Stoneman and Mike Scioscia are dumbfucks who don't know shit about baseball and think sending down the only consistently good pitcher on the staff will somehow help their last place team. It makes Angel fans sick.
