Question about ERA

[splintersag]

What happens to a pitcher's ERA if they come in, allow runs, and then leave without getting any outs.

 

For example, yesterday Marmol came in and allowed 4 ER and then left without recording any outs. His ERA went up from 2.09 to 2.93. What would it be if this was his first appearance of the year? Infinity?

 

The ERA formula is 9 * (ER/IP), but you can't divide 4/0.

 

Thanks in advance.

Yes...infinity if it was the first appearance of the year. Yesterday Marmol allowed 4 ER and got 0 innings to add, so his ERA shot up. It happens.
