The Seattle Mariners are looking to hold onto the final wild-card spot in the American League. They’ve struggled for weeks after the trade deadline, despite adding on in a big way, but the lineup is beginning to hit its stride again.

Seattle will need to continue to get better as the season comes to an end, but it’s still the Mariners’ wild-card spot to lose. If they can clinch the postseason, they’ll need to make some very tough roster decisions over the next few weeks, specifically with their potential postseason roster.

FanSided’s Chris Landers recently suggested that starting pitcher Luis Castillo could be at risk of missing the postseason roster this season. Castillo has been a staple in the Mariners’ rotation for the last few years, but he’s at risk of missing the postseason roster now.
