Mariners' Nick Rumbelow: Designated for assignment

Rumbelow was designated for assignment by the Mariners on Friday.

Rumbelow made three appearances for the Mariners back in March but was removed from the 25-man roster after allowing four runs while recording just four outs. Since then, he's allowed 16 earned runs in 15.2 frames for Triple-A Tacoma, leading to him being removed from the 40-man roster as well. Andrew Moore was claimed off waivers in a corresponding move.
