The Pirates have acquired Russ Canzler from the Orioles, according to his agent, William Appleton (Twitter link; hat tip to Roch Kubatko of MASNsports.com). Kubatko tweets that the Orioles will receive right-hander Tim Alderson in the deal. The Orioles PR department has confirmed the move.
Canzler, 27, was designated for assignment when the Orioles acquired Alex Liddi (another DFA casualty) from the Mariners. In 374 plate appearances for Triple-A Norfolk this season, Canzler hit .276/.369/.430. Canzler is primarily a first baseman but also has significant experience in left field and at third base. The former has appeared in 29 big league games — three with the Rays and 26 with the Indians.
Alderson, 24, was a one-time top prospect with the Giants after being selected 22nd overall in the 2007 draft. The Pirates acquired him in a trade deadline deal for Freddy Sanchez in 2009, and it was considered to be an impressive pull for the Buccos at the time of the deal. Alderson's star has faded, however, and after failing as a starter he's been shifted to the bullpen. In 29 relief appearances at Triple-A this season, he has a 2.43 ERA with 8.9 K/9 and 1.9 BB/9. He did not rank among the Pirates' Top 30 prospects in either of the past two seasons, according to Baseball America.
