Keeping Score: Match for Jake Arrieta’s Second Half: A Giant’s Forgotten Season of 1916
Arrieta was reported to have set a record when he compiled a 0.75 E.R.A. in the second half of the season, after the All-Star break. But in 1916, there was no All-Star break, and Ferdie Schupp’s 0.71 E.R.A. was better than Arrieta’s.
