With just a week and a half until the trade deadline, the Mariners have played their way into an interesting position. They’re three games back from Oakland in the AL Wild Card race, and play the A’s and the Astros at home heading into the deadline next Friday. Those seven games against the top two teams in the division will serve as a barometer of Seattle’s ability to stick in the playoff race for the rest of the summer. Their record says they’re probably good enough to think about adding a piece or two before the deadline, but their underlying metrics say they’re probably not good enough to stick around in the race.
