- Step 1
Add up the total innings pitched. For every out that is recorded while you are pitching, you get one-third of an inning.
- Step 2
Add up the total number of earned runs given up. If there are no errors in the inning, all the runs are earned runs. If there are errors, reconstruct the inning without the errors to see how many runs would have scored if the fielding had been perfect.
- Step 3
Multiply the earned runs by 9.
- Step 4
Divide by the total innings pitched.
- Step 5
Round the number to the second decimal place. For example, 3.2051 is 3.21.
This blog is all about Yankees!!! Love them or hate them, they are a great team! The Yankees have a lot to offer to education. In discussing player salaries, student can learn what it looks like to see and how it feels to write figures such as $33,000,000.00 or $22,600,000.00. They can also learn about greater than and less than by comparing the win/loss record - 59(W) 34(L)or the win/loss record of a pitcher such as Andy Pettitte 11(W) 2(L).
