Mariners defying logic with one-run dominance

From 1976-80, the San Francisco Giants won 75 or fewer games each season … except one. In ’78, kind of out of nowhere, the Giants won 89 games and sort of contended for the National League West title. What happened to those Giants? They won 42 games by one run. Well, in 2018, the Mariners are in the midst of potentially an even more remarkable run.
