It is determined by dividing the number of earned runs allowed by the number of innings pitched and multiplying by nine.
In modern baseball, an ERA under 2.00 is considered exceptional and is rare. An ERA between 2.00 and 3.00 is also considered excellent and is only achieved by the best pitchers in the league. An ERA between 3.00 and 4.00 is above-average.
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).
In baseball statistics, walks plus hits per inning pitched (WHIP) is a sabermetric measurement of the number of baserunners a pitcher has allowed per inning pitched. WHIP is calculated by adding the number of walks and hits allowed and dividing this sum by the number of innings pitched.
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.

So, what’s a good ERA for a closing pitcher? A good ERA for a closer is between 2.00-3.00, which means the pitcher will allow two to three runs per nine innings on average. Closers typically pitch one inning in a game, which translates into an ERA that is generally lower than other types of pitchers.
What is this? That said, as an unofficial benchmark, in the 21st century, an ERA below 4.00 is considered good, and an ERA below 3.00 is great, and below 2.00 is exceptional. An ERA above 5.00 is generally considered poor.
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.

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.
Strikeout to walk ratio (K/BB): You can’t simply look at strikeout-to-walk ratio and make firm judgments about a pitcher. But as supporting evidence goes, it’s one of the most useful “eyeball” stats out there.
OBP refers to how frequently a batter reaches base per plate appearance. Times on base include hits, walks and hit-by-pitches, but do not include errors, times reached on a fielder’s choice or a dropped third strike.
However, WHIP is a better isolation of pitcher performance in many cases than something like ERA because it’s based on individual events rather than a sequence of events. In other words, it’s easier for one bad play on defense to tank your ERA than your WHIP.

According to Baseball USA, the average time from home to first base (70’) for a 12-year old is 4.35 seconds or 16.1 fps. The average time for a 13-year old (80’ bases) is 4.79 seconds or 16.7 fps.
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.)
