How to find an era in baseball?


Question:

Answers:

Who were the most patient hitting teams in MLB last year, in terms of pitches seen per plate appearance?

Take the number of Earned Runs allowed, divide it by the total number of innings pitched, then multiple by 9.

If in 1 game a pitcher pitches 6 innings and gives up 3 earned runs, his ERA is 4.50 (3/6 * 9 = 4.50).

This obviously holds true over a season. Say a pitcher goes 180 innings (30 starts averaging 6 innings per start) and gives up 60 earned runs, he has a 3.00 ERA (60/180 * 9 = 2.999999999997 = 3.00). He'd have a 2.00 ERA had he given up 40 earned runs, and a 4.00 ERA had he given up 80 earned runs.

Also, every out a pitcher records counts as 1/3 of an inning. So if a pitcher pitches 6 innings without giving up a run, then gives up a run in the 7th inning without getting an out and is then pulled, his stat line reads as 1 ER over 6 IP. Just a quick example of the math as well: John Smoltz pitches into the 6th inning but only gets two outs before he is pulled. He pitched then 5 full innings and 2/3 of an inning, for 5 2/3 innings pitched. John gave up 5 earned runs in his 5 2/3 IP, for an ERA of 7.94 (5/5.66667 * 9 = 7.94).

Who is the best venezuelan short stop?
