The American League champion Yankees tonight begin their stint hosting the World Series, and Blue Triton Brands, one of MLB’s newest corporate sponsors, is activating with an out-of-home ad campaign from agency Doner. Billboards and transit ads bearing Yankees and MLB indicia will declare Blue Triton’s Poland Spring brand, “The Official Water of Rally Caps.’ A similar effort in and around L.A. dubs Arrowhead water “The Official Water of the National Anthem.”
