could have found the data. It simply had not written a query to do so. I have had a subscription for many years and I spent a fair amount of time poking around but I came up empty. Finally, I sent a message to Baseball Reference and it confirmed that it did not have a query to do it:
Hi Kenneth,
Thanks for the question. Unfortunately there is no way to do that type of search using any of the Stathead tools. We're very sorry about that. If there is anything else I can help with, please let me know.

What was I looking for?
None allowed Home Runs to all four. Click link view all data _________________________
The Gumpert post made me wonder if any pitcher had allowed Home Runs to all four Yankee greats. I was pretty sure that none had but I needed to check. Where better than the Home Run Log in Baseball Reference?
When I couldn't find a query to provide the data I dragged it out of Baseball Reference for each of the four Yankees and put it into a spreadsheet. The link for that is in the "27 pitchers" post and repeated here:
Click link view all data.
For instance, here is the Home Run Log for Babe Ruth:
Right at the top:
It tells me that Ruth homered off 216 pitchers and lists the top ones. If I click "Show All", it does. I highlighted all and did copy/paste into my spreadsheet. Repeat for the other three Yankees and I had the data to work with.
Note: I pulled the data into Microsoft Access, a single user Database Management System (DBMS). But Access must be maintained by _____ (less than competent people) these days and it did not perform what should have been as easy task.
Eventually I matched things up and filled out a master list of the 27 pitchers who allowed at least one home run to three of the four Yankees. Ruth had the most of the four Yankees against any pitcher: 17.
Then I wondered if any batters hit more than 17 HR against any pitchers. I remembered that Willie Mays hit his first and many more against fellow Hall of Famer Warren Spahn.
Home Run Log for Willie Mays:
Mays off Spahn take the lead with 18. But it's not practical to search this way, especially when the data is obviously in at least one baseball database.

I figured, what the heck. Let's try Google search, which has been beefed up with Artificial Intelligence (AI) using its Gemini software.
At least 17 career home runs against individual pitchers?
AI Overview
In Major League Baseball (MLB) history, there are exactly five instances where a batter hit at least 17 career home runs against an individual pitcher. [1]
This exclusive, all-time power list features the following batter-versus-pitcher matchups: [1, 2] This exclusive, all-time power list features the following batter-versus-pitcher matchups: [1, 2] - 19 Home Runs: Duke Snider against Robin Roberts

You can dive deeper into these legendary individual matchups and their full career statistics on Baseball-Reference.

Note the ironic mention of Baseball-Reference.
I checked each of the five and the numbers are correct. I could not check for a number higher than 19.
Home Run Log for Duke Snider:
___________________________
The footnotes offer confusing stuff.
Which MLB player holds the record for most home runs hit off of one pitcher?
______________________________
It has the answer and ironically, shows what appears to be a copy/paste of Duke Snider's career stats against fellow Hall of Famer Robin Roberts from ... Baseball Reference.
If it also shows how the Quora guy, Christopher Pellerito, found the data, I did not see it. I'm not familiar with Quora.
So maybe all Google AI did was grab this. But it had other footnotes.
Here's the next:
Willie Mays holds the record for hitting home runs in the most different innings. Mays hit at least one home run in every inning from one to sixteen. His first-inning and sixteenth-inning home runs, both off Warren Spahn, are the most noteworthy. The one in the first inning was the first of Mays’s career, and the sixteenth-inning blast broke up one of the all-time great pitching duels and provided a 1-0 victory for Juan Marichal. __________________________
Interesting but it has nothing to do with my question.
Further down but not a footnote:
which player has the most home runs against a single pitcher all-time
11 (eleven):
Rickey Henderson off Frank Tanana
Gary Carter off Steve Carlton
Mike Schmidt off Steve Forsch
____________________________
Incorrect.
That's enough.
Did Google AI have a lucky guess? How did Quora guy Christopher Pellerito come up with the answer? I could not figure out how to ask him.
