As much as I hate the idea of Z coming back to pitch, I love the attitude. The Cubs need more Z type players and more managerial types with enough common sense to tell him 'no'.
Everyone should know, part of being a Cub is being timed in the 40. I am confident that Dusty, being such a student of the Cub minor league system, was well aware that Mateo could outrun Soto.
On the bright side, Ron Santo appears to be taking this all in stride. Sure, he's screamed and raised his blood pressure a few times, but at least he didn't doesn't sound like somebody shot his grandmother.
