Which teams had the largest differentials between their blowout winning percentage and their non-blowout winning percentage?

I used the Baseball Reference Situational Records tool. I found every team's record since 1901 in blowouts and in all other games then found the difference in winning pct. The 1931 Yankees do have the biggest differential of .330. The 1958 Reds are 2nd with .324 (.750 - .426).
