The Athletic's Dan Hayes mentions briefly that the Twins are more interested in Tyler Mahle than they are Luis Castillo.
Mahle doesn't have the eye-popping stats of Castillo but would be a considerable upgrade to the Twins' rotation, as would Castillo. If the Twins are pursuing Mahle over Castillo, is it due to price, untapped potential, or both?
I still think Montas is a long shot, the A's seem to be really intent on asking top dollar for him. If they haven't already overplayed their hand, I think there's a good chance they'll end up doing so.
