How Is ERA Different For A Starter vs. a Reliever?

Many factors make up the difference between being a starter and reliever, but one of them is how long you can last in each game. For example, a starter might only get six scores during the day. Therefore, they have to pace themselves accordingly by not throwing as hard or putting pitches right where batters won’t hit it too often, if at all!

Unlike starters, relief pitcher(s) typically assume their role by coming on for six outs at once throughout your scheduled nine-inning contest. They only need to navigate through one inning. This means guys who enter emergency plans have plenty of opportunities not just to stand tall against hitters but also throw harder than ever before since it’s much faster-paced than what we are witnessing from longer-inning performers. Moreover, a reliever might give up earned runs, so their ERA will not be higher than a starter.

Can You Have A Zero Era?

Some ERA listings may be “zero”, or we call undefined and infinite. In reality, the player’s skill level is too high for an accurate score, so it does not accurately reflect their ability. 

People often report zero ERAs at the beginning of the season before they have enough data to calculate them accurately. If they allow one or more earned runs without retiring any balls, technically, their ERA will be zero since no scores were reported. However, this score has never remained the same for the whole season.
