You may want to try to track down one of the older Shadowrun books, "Wolf and Raven" by Mike Stackpole, set in Seattle (the default Shadowrun setting) where there's a number of references to the Mariners.

Or as they get referred to, the Seadogs.

(There's even a story involving baseball in an age of cybernetics and magic which is actually kinda fun.)
