Players who had a six-year period when they led MLB in both OBP & SLG

I had bases.chat, the AI program created by SABR member Ted Ingram, find all of the data in the table below. Then I verified the data using Stathead from Baseball Reference. The search covered the years 1901-2025.

Yesterday's post listed all the players with both 400+ HRs and a .400+ OBP. Mike Trout was one of the fourteen players. I also noticed that he led all of MLB in both OBP & SLG over the years 2014-2019.

So I wanted to find out how many different players had done this. There are 12 different guys in the table below. For most guys, I show just their first six-year period when they did it. 

Most of the batters had overlapping stretches. Wagner, for example, also did it from 1904-1909 and 1905-1910. That gives him three periods, as shown in the last column. If a player is listed more than once, that means he had at least two non-overlapping six-year periods. Ruth did it over the years 1915-1920 and then did it from 1921-1926 and then from 1927-1932. 

To qualify, a batter needed 1,800+ ABs for any six-year period.

Close calls: Giambi (440, .399), McGwire (583, .394) and Sheffield (509, .393). 

If Trout gets 2000 more PAs he would need about a .381 OBP to stay at .400+.

This next table has active players with 200+ HRs and a .375+ OBP.

Soto, Judge & Alvarez look like possibilities to make it at some point.
