That was Bob Gibson, whose 1.12 ERA remains the lowest for any starting pitcher since Dutch Leonard in 1914, and the fourth-lowest of all time, dating back to 1876. In that year Gibson pitched 13 shutouts -- since 1998, no MLB starting pitcher has had 13 complete games!
Babe Ruth, pitching for the Boston Red Sox had the best ERA in 1916. It was 1.75. That's a low ERA for people not familiar with the game.
Wade Boggs pitched one inning and gave up no runs.
Tim Keefe of the 1880 Troy Trojans had a 0.86 ERA in 105 innings and is generally considered as having the lowest ERA in an MLB season as the 1880 season was only 84 games long. Since 1900, the lowest ERA belongs to Dutch Leonard of the 1914 Boston Red Sox at 0.96. He had a 19-5 record and threw 224 2/3 innings.
