With Houston 4 games ahead of Seattle in the American League West, the division is far from decided. The Mariners and Astros still face each other 13 more times, and these matches could more than likely decide who punches their ticket to the ALDS.
But, as of now, the Mariners sit in the second wild-card spot. The team closest to Seattle in the standings is Oakland, yet they are still six games behind. Rarely do teams have a six-game advantage over the next closest opponent in the wild-card race, let alone before the All-Star break. For example, six teams currently dwell within six games of the second wild-card Atlanta Braves in the National League.
