I am currently collecting the 1963 Topps baseball set and today I received card #117 Jacke Davis. As with each card I get I look up his career on B-R. I noticed he only played a few games(48) in the majors and saw he only one home run. I checked the game logs and noticed his only home run was against Sandy Koufax(two out ninth inning pinch hit 3 run job no less! Ruining A 2 hit shutout as well!). Which leads me to this question, Who else(if any) has hit his only home run against a Hall Of Famer?I found this comment interesting because for a while now, I have been thinking about using something similar in a trivia question. Instead, let's use it as a readers research question and I'll explain how you can use the Baseball-Reference.com Play-Index to find this on a case-by-case basis.
On every player page on BB-R there is a section called HR log. This information which was gathered by the SABR is available for both home runs by hitters and home runs allowed by pitchers. If saved as a URL (by clicking share) it is also searchable by the season finder.
Therefore, if you save all the home runs allowed by Sandy Koufax and use that saved search as the basis for a batting career home run search, you can see which players that homered off Koufax and had only 1 career HR. Of course, it would be prudent to check if anyone hit multiple HRs off Koufax and not anyone else, but that can also be easily done with the new list.
To create a complete list, all we would have to do is check all of the HOF pitchers, which may be somewhat time consuming individually, but should be quite easy as a group.
Here are the 68 Hall-of Famers who pitched at least 450 innings in the major leagues. If you check one of them, even if there result is that there are none, let me know in the comments and I'll put it in the chart:
