While scanning for reference photos of brains, I found this baseball card for David Leonard Brain. He played for the Reds, the Giants, the White Sox, the Cardinals and the Boston Beaneaters. 🙂 You can get all his career details from baseball-reference.com, including the fact that he lead the league in 1907 with 10 homers.
Strangely enough, Dave Brain seems to be a really popular name.
Addendum: Dave Brain is the only NL player to have three triples in a game twice in one season. How is that for a bizarre record?
