According to various reports, the Mariners have a "strong interest" in Alfonso Soriano. (See here and here.) I'm not seeing it. The Mariners are in no position to trade a top prospect or two for a "rent-a-player." Yeah, they're only four games back (going into Monday), but does anyone seriously believe this mediocre-at-best team has any legit playoff shot? Soriano, a free agent at season's end, isn't likely to stay in Seattle. He wants to play second base and the Mariners have an All-Star second baseman. And he wants tons of cash. The Mariners might have the salary space, but I don't think it's necessarily a given considering they will have more than $56M tied up in their six highest-paid players next year.
Then again, few -- very few -- of the Mariners' moves this season have made sense. So, expect this deal to go through ASAP.
