Mariners' Ryan Weber: Designated for assignment Monday

The Mariners designated Weber for assignment Monday.

Analysis:

The move was done to make room for Rob Whalen on the team's 40-man roster following his acquisition by trade Monday. The 26-year-old Weber was just claimed off waivers by the Mariners earlier in November; his future with the organization is unclear, but he could land in the minors as bullpen insurance for when injuries strike next season.
