In baseball statistics, Earned Run Average, or ERA, is one of the most well-known pitching statistics and represents the average number of earned runs a pitcher will give up per nine-inning game.
In baseball, an earned run is any run for which the pitcher is held accountable (i.e., the run scored as a result of normal pitching, and not due to a fielding error or a passed ball). Any runner(s) who tags his base and reaches home plate is scored against the pitcher as an earned run(s).
An ERA between 4.00 and 5.00 is average; the majority of pitchers have an ERA in this range. An ERA above 5.00 is generally considered below-average, and a pitcher with an ERA above 6.00 for a prolonged period of time is usually in danger of demotion to the bullpen or a lower league.
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.

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.
The scoring symbol “K” was first used in the scoring of an actual game in 1868. One reason the letter “K” was used because “K” was the prominent letter of the word strike. Another reason the letter “K” is used is that it is made with 3 strokes of the pencil, symbolizing the 3 strikes for the strikeout.
There are two outs when a batter hits a ground ball to short. The shortstop boots it and the runner reaches first base. The next batter hits a home run. Those two runs are unearned because the error should have been the third out of the inning.
The purpose of the unearned run is to distinguish which runs a pitcher is at fault for allowing. Unearned runs do not count against a pitcher’s ERA.

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.

Team innings per game is used to calculate Earned Run Averages (ERA).
Definition. WHIP is one of the most commonly used statistics for evaluating a pitcher’s performance. The statistic shows how well a pitcher has kept runners off the basepaths, one of his main goals. The formula is simple enough – it’s the sum of a pitcher’s walks and hits, divided by his total innings pitched.
The formula for finding ERA is: 9 x earned runs / innings pitched. If a pitcher exits a game with runners on base, any earned runs scored by those runners will count against him.

Baseball (MLB).
The modern record (i.e., post-1900) for margin of victory was set in 2007, when the Texas Rangers defeated the Baltimore Orioles, 30–3. (The 30 runs are also a modern-era record for runs scored in a nine-inning MLB game by one team.)
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.
The name “live-ball era” comes from the dramatic rise in offensive statistics, a direct result of a series of rule changes (introduced in 1920) that were colloquially said to have made the ball more “lively”. The live-ball era was the era in which baseball regained relevance and exploded in popularity.
