9:12pm: The Marlins haven't formally denied the Orioles' request to interview Jennings, but it's leaning that way, according to Dan Connolly of the Baltimore Sun (on Twitter).
2:30pm: The Marlins have denied the Orioles permission to interview vice president of player personnel and assistant general manager Dan Jennings for their GM opening, tweets Roch Kubatko of MASNSports.com. Jennings is signed through 2015 from an extension signed in '07, and Dan Connolly of the Baltimore Sun reported that the Marlins have denied teams permission to interview him three times in the past. Jennings has been with Florida since 2002, prior to which he worked for the Devil Rays, Mariners, and Reds.
Kubatko notes that Arizona's Jerry Dipoto will interview for the Orioles position today, while Toronto's Tony LaCava is scheduled for tomorrow.
