The most notable change is the promotion of pitching coach Dean Treanor from Double-A Altoona to Triple-A Indianapolis, where he'll take Ray Searage's place. The Bucs added Searage to their Major League staff in October.
The Pirates hired Tom Filer to take Treanor's position in Altoona. Filer spent the past six seasons coaching in the Phillies' Minor League system, most recently with short-season Williamsport (Pa.).
Pittsburgh's only other addition to its Minor League coaching staff is Mike Lum, who will coach with the Gulf Coast League Pirates. Lum was Milwaukee's Minor League hitting coordinator for the past three years and has over 25 years of coaching experience.
Also, pitchers Phil Dumatrait and Eric Hacker will not be returning to the organization. Dumatrait, who became a free agent last week when the Pirates decided not to offer him a contract, has signed a Minor League deal with the Tigers.
Hacker has signed as a Minor League free agent with the Giants. Pittsburgh acquired Hacker in May when it traded right-hander Romulo Sanchez to the Yankees. Hacker made three September appearances for the Pirates.
