Today's DFA's: Mulvey, Miller, Lebron

Let's mix it up a little bit with some actual MLB news here, and cover the players that were designated for assignment today. After all, we all know that countless players that signed yesterday will one day have the honor of being designated for assignment by some MLB organization.

• The Orioles designated reliever Luis Lebron for assignment today, according to Jeff Zrebiec of the Baltimore Sun. The move frees up 40-man roster space for 2011 first-round pick Dylan Bundy, who signed a Major League contract yesterday. Lebron, 26, hasn't gotten past Double-A yet after missing the 2010 season with Tommy John surgery, and he just recently got back on the mound. He's a legit power arm, though, and should presumably find a spot somewhere.
• The Blue Jays announced today that lefty reliever Trever Miller has been designated for assignment in a series of moves to free up roster space for pitchers Wil Ledezma and Rommie Lewis. Miller, 38, hasn't been effective since 2009, but his high-80's velocity is still there and he'll probably catch on somewhere given the scarcity of quality left-handers in the game.
• The Diamondbacks designated Kevin Mulvey for assignment this afternoon in order to free up roster space for the call-up of Wade Miley, as the team tweeted. Mulvey, 26, was once a top prospect with the Mets and he spent time in Minnesota after being included in the Johan Santana deal, but he's struggled in Arizona's Triple-A rotation for the past two seasons.
