Montero was designated for assignment Monday, Oscar Hueto of MLB.com reports.

EDGE Analysis

Montero was put on waivers over the weekend, and Monday's move likely means a team(s) put in a claim and the Mariners pulled him back with the intent of trading him. The Mariners have 10 days to work out a deal or release him as he is out of options. In any event, Montero's time as a Mariner looks over.
