Kiernan, from the Bronx, left Georgetown in 1941. He played pro basketball and also pitched some minor league baseball that year, first with Brattleboro and then in Bennington (both clubs are in Vermont.) He later pitched for Bridgeport (Connecticut) in 1947.
* The Brewers were a member of the ABL at this time, but it does not appear like Kiernan played in any league games; only in exhibition games.
