10:48pm: The Orioles may already have fired Trembley, according to ESPN.com's Buster Olney (via Twitter). Olney's source says the change was "inevitable."
9:36pm: Jeff Zrebiec of the Baltimore Sun passes on word from Connolly that "it's not normal for [MacPhail] to meet the club when it returns home from a road trip," but that's MacPhail did this evening.
1:35pm: The Orioles may fire manager Dave Trembley soon, though nothing is official. Dan Connolly of the Baltimore Sun reports that president of baseball operations Andy MacPhail will likely meet with Trembley before tomorrow night. A source familiar with MacPhail's thinking told Connolly that a meeting between MacPhail and Trembley could take place tomorrow morning or even tonight, when the Orioles return from Yankee Stadium.
Connolly hears that the O’s will hire from within the organization if they make a change, so Juan Samuel and Jeff Datz are options. Connolly expects the interim manager to be “a placeholder” to steer the team while MacPhail looks to hire someone permanently.
The Orioles are 15-39 under Trembley this year and they have lost eight consecutive games. In parts of four seasons, the team is 187-283 under Trembley. This afternoon the Orioles lost to the Yankees in New York, so it's not getting any easier for the 58-year-old Orioles skipper.
