Who has the best ERA for a MLB season
T. Hudson with a .270 ERA
Johan Santana
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.
The Los Angeles Dodgers
That was Pedro Martinez of the Boston Red Sox at 2.22.
