How do they figure a pitcher's ERA when he gives up 4 or 5 runs in an inning without getting an out?
 
You don't. It is marked infinite....and I'm not even joking.

The key is, is this a single appearance in a career or will he have other opportunities? There is an actual Infinite ERA club. About 15 guys

Sorta like the polar opposite of the Mile High Club...Except, of course, for the fact they actually did get to play in the bigs. Which is pretty cool.

So if I look at Rosenthal's stats his ERA will show infinite?

Depends on who you get your stats from, but most will actually show the symbol or say Inf.

Baseball Almanac shows the symbol. Baseball reference uses Inf.

Look up a good friend of mine on BB Ref....Steve Luebber. You'll see there

I was figuring on looking at the stats on the Cards website.
 
MLB doesn't track it that way, you'll have to use a 3rd party site. Their Game Logs track the overall ERA, not individual games

Overall is what I wanted to know about, I don't care about one game. What did that game do to Rosie's ERA? If it's infinite for a game how can you say what it does to the ERA for the season?
 
It's infinite for the game

He's recorded at least 1 out this season, so then it's based on Runs/9 innings. He's ERA jumped from 1.6 to 2.14. So nothing at all changes other then it just skyrocketed because he never recorded an out.

How can you figure out how much to add to his runs per 9 innings when he didn't record an out?
 
Because it's based on the innings he has already thrown. He has recorded 1 out this season, so you can calculate an ERA.

If that game was his 1st and only game....he would have an Infinite ERA
