History ERA(earned run average) was developed by

Henry Chadwick in the early 1900’s. It is used to see how good a pitcher is. WHIP(walks, hits, innings pitched) was created by Daniel Okrent in 1979 and it tells you how many base runners, on average, a pitcher allows per inning

ERA Formula

If you want to find a pitcher’s ERA you have to use this formula; 9(Earned Runs/Innings Pitched)

Ex. Someone gives up 2 earned runs over 8 innings. 1. 2/8=0.252. 0.25x9=2.25

WHIP Formula

To find a pitcher’s WHIP you have to use this formula; (Walks+Hits)/Innings Pitched.

Ex. A pitcher has walked 5 batters and allowed 10 hits over 25 innings.

1. 10+5=152. 15/25=0.60

Real Life Applications

Clayton Kershaw pitched about 198 innings last year. He gave up about 40 earned runs.

So, since 40/198=0.20 and 0.20x9=

1.80

Real Life Applications
