In baseball statistics, earned run average (ERA) is the average of earned runs allowed by a pitcher per nine innings pitched (i.e. the traditional length of a game). It is determined by dividing the number of earned runs allowed by the number of innings pitched and multiplying by nine.

The lowest single-season ERA in league history was posted by Tim Keefe, whose 0.86 ERA in 105 innings pitched for the National League’s Troy Trojans in 1880 led his closest competitor by . 52 runs. In the American League, Dutch Leonard’s 0.96 ERA is a single-season record.
Ed Walsh holds the MLB earned run average record with a 1.816.

WHIP reflects a pitcher’s propensity for allowing batters to reach base, therefore a lower WHIP indicates better performance. While earned run average (ERA) measures the runs a pitcher gives up, WHIP more directly measures a pitcher’s effectiveness against batters.
K/9 rate measures how many strikeouts a pitcher averages for every nine innings pitched. It is determined by dividing his strikeout total by his innings pitched total and multiplying the result by nine.
When it comes to Major League-caliber pitchers a good WHIP is around 1.00. Anything below 1.00 is outstanding (potential Cy Young worthy) since it demonstrates how dominant a pitcher is.
In general, an ERA in the range of 4.00 – 5.00 is considered a good career ERA, with the best pitchers being below 2.00. According to Baseball Almanac, Ed Walsh is credited with holding the career record for ERA with 1.82.
How Do You Calculate ERA For a 7 Inning Game? It is an estimation of pitcher’s performance that is determined by dividing the total of earned runs allowed by the total of innings pitched and multiplying the result by 7.
A huge part of determining a pitcher’s true skill level, though, begins with the basic walk and strikeout rates. A great place to begin with pitchers is to look at their K-BB%. This is the strikeout percentage (rather than K/9) minus their walk percentage. The higher that number, the better.
Outfielder Ty Cobb, whose career ended in 1928, has the highest batting average in Major League Baseball (MLB) history. He batted . 366 over 24 seasons, mostly with the Detroit Tigers.

Completely unofficial and no record books have ever been kept. The following pitchers had no problem with their pitch count, at least for one inning, as they started the inning, threw exactly three pitches and recorded three outs.
Infinity ERA, also known as infinite ERA, is when a pitcher allows one or more earned runs without recording a single out. ERA is calculated by dividing earned runs by innings pitched and multiplying by 9, but if no outs are recorded then you would be dividing by 0, which equates to infinity.
