O's to bring Castro aboard as bullpen coach

The Orioles are expected to name longtime Milwaukee Brewers coach Bill Castro as their new bullpen coach, according to an industry source.

Castro, a native of Santiago, Dominican Republic, will give the Orioles a much-needed Spanish-speaking coach on the staff, a preference manager Buck Showalter has hinted at many times. The rest of Showalter's staff, which includes pitching coach Rick Adair, hitting coach Jim Presley, bench coach John Russell and first-base coach Wayne Kirby, is expected to be officially announced in the next few days with the holdup being the vacancy at third base.

When reached by phone, Showalter had no comment on his coaching staff, but he has said previously -- and reiterated on Monday -- that the club hopes to have a staff in place by next week's Winter Meetings.

A long-serving member of the Brewers' staff, the 57-year-old Castro was named bullpen coach in 1992 under first-year manager Phil Garner and -- while he had several stints as pitching coach -- predominately oversaw the Brewers' bullpen for 18 years. Castro has been serving as the organization's roving Minor League Latin pitching instructor although he spent the end of this season as interim pitching coach for the Triple-A Nashville Sounds following Rich Gale's resignation. He was also the Dominican Republic's pitching coach in the inaugural World Baseball Classic.

Castro and executive vice president of baseball operations Dan Duquette have a previous relationship from Milwaukee, when Castro was still pitching. Duquette got his start in professional baseball as a scouting assistant with the Brewers in 1980.
