As the Orioles march toward the end of their current lease at state-owned Camden Yards — but with promises to soon agree to a long-term one — Maryland’s treasurer is concerned there’s a holdup in negotiations and said the public is being kept in the dark. Treasurer Dereck Davis said Wednesday the drawn-out negotiation, in which he is not directly involved, between the Maryland Stadium Authority and the team makes him believe “there’s something that we’re not being told.” “It’s time to start putting timelines out there so we can get this damn thing done,” Davis said.
