There are a few reasons why I'm thinking this way. First of all, you mention the 69 coaches, so an on field feat is out. Then you mentioned that a Met could only do this four times. Like the 4 Met pennants. Buddy being the coach on one of them. But since no Met could do all four that was out. Maybe a playoff appearance? There were no LCSs in Babe Ruth's day. Belanger was in 6 LCSs with Balto. But then Ojeda never did it. So that's out. Dwight Bernard was a short timer, but he played when Milwaukee was a playoff team. Hmmm. Every guess, every lead, has a hole. I was hoping it isn't something dopey like being on the cover of a yearbook.
