NWSB Writer and Seattle Mariners Insider Brian Scott dives into the Seattle Mariners roster. Who will make the 25? Are the M’s a complete roster at this point? You have to have a backup catcher. It’s a given and Sucre is getting the nod. Bloomquist is healthy, under contract and is a wonderful bench player so I think his spot is safe. With the platoon situations in right field and at short you wind up with a four man bench.
