"Five days after leaving former ace Zach Duke off the 40-man roster, the Pirates traded him to the Arizona Diamondbacks for a player to be named later Wednesday.

The left-hander was designated for assignment Friday, just over seven months since he was the Pirates' Opening-Day starter for the second time since 2007. The '09 All-Star was 8-15 with a 5.72 ERA in 29 starts this year.

Duke, the Pirates' 20th-round selection in '01, was entering his final year of arbitration, and general manager Neal Huntington said last Friday that the sides could not reach common ground during discussions about his future with the team.

The Pirates announced their full '11 coaching staff yesterday, and there are some familiar names on the list.

Pitching coach Ray Searage, who replaced Joe Kerrigan in August and was well-liked throughout the clubhouse, and bench coach Jeff Banister, who replaced Gary Varsho at the same time, will be back in the same capacity. Also staying on will be bullpen catcher Heberto Andrade.

Banister was a finalist for the manager's spot, awarded to Clint Hurdle on Nov. 15."
