"Flannagan," The Mystery Beaver
This player who appeared only in the 1910 Obak set, with his name misspelled as "Flannagan" is one of the few whom I never definitively identified in my years of Obak research. It was only years later, as I began actually writing this series, that I found out who he was from the SABR Minor Leagues database.
My early notecard on Flannagan offered as possibilities James F. or Edward J., who had played the outfield and pitched, respectively, for the 1909 Vancouver Beavers of the Northwestern League. Neither played there in 1910. Since it is my impression that Obak made few, if any, errors such as producing a card for a player who wasn't on a particular team in the year the card was issued, I wasn't comfortable designating the card-guy Flanagan as either James or Edward.
S.S. Flanagan (his full name is not recorded by SABR, nor any biographical details), played for Vancouver in both 1908 and 1910. He is not shown as playing anywhere in organized baseball in 1909. He had batted .351 for the Beavers in 1908, but his a career low of .209 in 1910 and was demoted to the Class D Union Assn. at Boise for 1911.
He rebounded at Boise and hit .342. That earned him a call back to Class B play with Decatur of the Illinois-Indiana-Iowa League for the remainder of his known pro career (1912-1915).
