The Diamondbacks have acquired left-hander Zach Duke from the Pirates in exchange for a player to be named later, according to an Arizona team press release. The player to be named later is "a mid-level prospect" who can't be named due to the roster freeze leading up to the Rule 5 draft, reports Nick Piecoro of the Arizona Republic. If this player is actually taken in the Rule 5 draft, Piecoro says the Bucs and Snakes "have agreed to other players" to be dealt to Pittsburgh.
Duke, 27, was designated for assignment by Pittsburgh last week following a rough 2010 that saw the southpaw post a 5.72 ERA in 29 starts for the Bucs. A lifetime Pirate, Duke has a career 4.54 ERA in 160 games (159 of them starts) and a 1.88 K/BB ratio in six major league seasons. He provides Arizona with a veteran innings-eating option for their rotation, though his career-high 1.4 HR/9 last season might be of greater concern if he's going to be pitching at Chase Field.
Piecoro reports that the D'Backs will try to sign Duke to a contract worth less than his $4.3MM salary in 2010, and if the two sides can't come to an agreement by the tendering deadline, Duke will be non-tendered. (Both Twitter links)
