Trade last year's best player, who is controlable. Not my idea of how to make the(a) team better. There is upgrade pitching available, and it is getting cheaper by the day.
Not since the spawning of an aging asparagus have I heard such a dismal prospect. Even Tampa Bay doesn't trade a guy before he hits his peak. If death of snake bodes evil, trade of Rosario just spells trouble. Even a Yugo needs a spark plug, and that's just what Rosie provides - the plug that sparks this team to its heady glory.
Obviously we cannot bond permanently to our favorite players, nor can we put all our plugs in one basket. If Rosie brought us Kershaw, that's worth considering. A horse on the mound is worth two in the field. Otherwise, if baseball is sixty percent pitching, then an average pitcher is sixty percent of losing.
I'd keep Rosie around until somebody better comes along. That's nobody on today's Twins.
