RE: ERA
Andrew,
Yes, lower is better. Here's the calculation:
Think of it this way. Carlos Zambrano has a career ERA of 3.5. If he pitched the entire nine innings of the game, on average, the opposing team would finish with a score of 3 or 4 runs (assuming no errors resulted in unearned runs). Since as a starter he probably only pitches between six or seven innings, on average, when he's done pitching, the other team has scored 2, occasional 3 runs (again, assuming no errors).
Now, say we have a reliever who pitches only one inning each game but is almost always charged with an earned run, his ERA would be 9.
Does that make a little more sense?
