The Mariners have struggled this season, so they have been busy acquiring new players. Aplin will provide outfield depth but is not a great candidate to become an everyday player in MLB.

The Astros had designated Aplin for assignment recently, so they were at least able to acquire a future asset or cash in return. Houston has far better options in their outfield currently.

Aplin has some speed, but he is more of a fourth outfielder candidate in Major League Baseball. Therefore, he can be safely ignored in most fantasy formats until further notice.
