I think Chip owes the fans an explanation.
I also see that it is Chip, and not his Pitching Coach, who has been making trips to the mound recently without taking the pitcher out. That's a change from the tradition of sending his Pitching Coach!
I posted an opinion some time ago that Mike Harkey (whose previous experience was that of a bullpen coach in the American League) has shown himself to be marginal at best.
I am just not impressed with the way he talked at his Pitchers when he was making the trips to the mound. Perhaps that is why he is no longer doing it.
And I am not impressed with the tone of his comments in interviews. If he can't motivate the fans, how can he motivate million dollar ballplayers?
