Hi, and welcome to another edition of Dodgers Dugout. My name is Houston Mitchell and I'm beginning to think that Matt Kemp might just make the roster.
ERA+ compares a pitcher's ERA to the league average and adjusts for the pitcher's home ballpark, considering whether it is a pitcher's park or a hitter's park. A league average pitcher has an ERA+ of 100. A pitcher with an ERA+ of 110 is 10% better than a league average pitcher, one with an ERA+ of 90 is 10% worse.
FIP: FIP focuses solely on the events a pitcher has the most control over — strikeouts, walks, hit by pitches and home runs.
