Since ERA is calculated by dividing by innings pitched, if a pitcher fails to record an out, his ERA will be infinity. This has probably happened over a thousand times.
The next best answer is: On 8/13/2006, Kansas City's Luke Hudson pitched 1/3 of an inning and allowed 10 ER against the Indians, for a one-game ERA of 270.00!

Who has the best ERA for a MLB season
In MLB, no ... it is above average. In the 2011 MLB season, the average ERA in the National League was 4.16 and in the American League was 4.43. There have been seasons in MLB where the average ERA was 5+. In the AL, average ERA in 1996 was 5.00 and 1936 was 5.04. In the NL, average ERA was 5.33 in 1893. Those are the only three seasons in MLB where the average ERA was 5+. In other levels of baseball, 5.26 may be pretty good but not in MLB.
