From bRef's Bullpen wiki: Joe Stanley broke in as a pitcher but got most of his playing time as an outfielder. Stanley was a major leaguer at age 16 with the Washington Senators for one game in 1897. Although Stanley broke into the majors in 1897, he was still alive in 1966 when Nolan Ryan broke into the majors. Stanley died in Detroit, MI in 1967, a few months after John Smoltz was born there in the same year.
I'm a bit concerned about editorial QA/QC in the Bullpen... but then again when people ask me about events in the 60's, I too just answer by stating the year it happened relative to Nolan Ryan's birthdate... Who doesn't?
On the facegen, my in-game one was awful, so I started anew...
