Top prospect Matt Wieters, who is the only one of the Orioles' elite prospects that is still in camp, probably will be sent to minor league camp very soon. Manager Dave Trembley said today that he wants to start playing the regular starting lineup over the next few days. That, and the fact that the club will play three of the next four games on the road, point to the possibility of Wieters getting optioned to the Norfolk roster by this weekend.
