Highest Team OPS Differentials, 1901-2021

OPS Differential is a team's OPS minus the OPS it allowed. I have posted on this before using data from searches at Stathead. But Stathead is probably wrong on SLG allowed for many teams in the past. It might have something to do with not knowing how many 2Bs and 3Bs a team allowed.

For example, in 1920, the AL had a league SLG of .387. But BB Reference shows in the pitching splits that AL pitchers allowed a .373 SLG. BB Ref shows that the White Sox that year allowed an SLG of .371 while Retrosheet shows .380.

So for all teams from 1951-59 I replaced the OPS allowed that I found from a Stathead search with what can be found at Retrosheet. I stopped at 1959 because that is when I started to get agreement for all teams from both websites.

Click here to open an Excel file that has all the teams from 1901-2021.

The table below has the top 25. HOPS is the OPS a team's hitters compiled and POPS is what their pitchers allowed. The Dodgers the last 3 years claim 3 of the top 12. Of course, 2020 was a short season with only 60 games. This shows how dominant the 1927 Yankees are. Also, it is actually the top 26 since the last 2 teams each have a differential of .115
