Context in baseball is rarely, if ever, limited to just one play. Last night’s game between the Seattle Mariners and the Texas Rangers was a garden of context, the roots feeding heartily on events and narratives that have been budding all season, and even before. The series before this, in the home ball park of the Rangers, the Mariners were swept. Their dismal record against that opponent going into that series, one win and five losses, became a blighted one-and-eight. A striking blow not only because of the self-contained implications of playing poorly against a division rival, but in particular for what it meant for Seattle’s postseason hopes.
