WHIP is a new statistic for pitchers and it means Walks plus Hits per Inning Pitched. You add up the number of hits allowed and add to the number of walks allowed and divide by innings pitched. If a pitcher has walked 50 batters and given up 150 hits and pitched 180 innings, the WHIP would be calculated as (50 + 150) / 180 which equals 1.11.

When was it established that there will be 9 innings in a major league baseball game?

Not sure all the arguments for and against this but it was done here and for this reason. I would guess a time factor was involved. March 7, 1857 Event: Baseball decides 9 innings constitutes an official game, not 9 runs

Does ERA change if you play 7 innings?

ERA stands for Earned Run Average. The number of innings per game determines how ERA is calcuated. In Major League Baseball they play 9 innings so ERA is calculated with this equation, Earned Runs divided by 9. High School baseball (at least where I am located) plays 7 innings as a regulation length game. In this case a pitcher's ERA is Earned Runs divided by 7. In Little League the a regulation game is 6 innings, so ERA would be determined by Earned Runs divided by 6. If you are playing a game and it goes in to extra innings then a pitcher's ERA is not affected by the extra innings. If a regulation game is 6 innings, and the game goes into the seventh inning, then a pitcher's ERA is still determined by # of earned runs divided by 6. In summary ERA is ALWAYS determined by the amount of Earned Runs allowed divided by the number of innings played (not including extra innings).

What does the abbreviation era stand for in baseball?

The ERA in baseball stands for Earned Run Average which is the average amount of runs given up by a pitcher per game. For example a 1.98 ERA is amazing but a 6.10 ERA is terrible. The lower your ERA the better.

Who was the last major league pitcher to have an era under 1?

Well, for a pitcher to qualify for the ERA title in a season he must average at least 1 inning pitched for each game the team plays. There have been only two pitchers in MLB history that averaged at least 1 inning pitched per team game and ended the season with an ERA less than 1 ... the most recent being Dutch Leonard of the 1914 Boston Red Sox who pitched to an ERA of 0.96 (24 earned runs in 224 2/3 innings pitched). Tim Keefe of the 1880 Troy Trojans had an ERA of 0.86 (10 earned runs in 105 innings). The Trojans played 83 games in the 1880 season. Closer Dennis Eckersley of the 1990 Oakland Athletics pitched to a 0.61 ERA (5 earned runs in 73 1/3 innings).


In baseball how does a pitcher qualify for an ERA or Wins title?

For a pitcher to qualify for an earned runs average or wins title in the MLB he must have a minimum of 1.0 innings pitched per game. Therefore he must have a minimum of 162.0 innings pitched for the season

Which pitchers had more starts than walks?

A better measure of a pitcher's control would be fewest walks per 9 innings. About a dozen pitchers had a ration below 1.0, which means (on average) they would walk fewer than one batter for every nine innings they'd pitch. The all time leader was Candy Cummings, who had an average of .47; and, in his career, started 241 games but only walked 113 batters. Note, however, that record-keeping was less precise in the 1870s than it is today.


What is better a high ERA or a lower ERA?

A lower ERA is better in baseball because it reflects how many earned runs a pitcher allows on average per nine innings pitched. A lower ERA indicates better performance by the pitcher in preventing runs from scoring.
