On the Mariners’ huge-o-meter — a very scientific measuring tool, by the way — this three-game series against the Oakland Athletics ranks as hilariously gigantic.
It’s laughable because, over the past decade, the Mariners have played so few important summertime games. It’s easy to get carried away over a July matchup featuring a playoff position-jockeying M’s squad against the best team in baseball. The season is still less than 60 percent complete, which is plenty of time for a collapse. But this feels like a mid-September type of challenge, even though the Mariners have struggled over the past week.
