PITTSBURGH -- The Pirates continue to methodically fill out manager John Russell's coaching staff, with the latest announcement being the addition of Jeff Andrews as the team's new pitching coach.

Named the successor to Jim Colborn, Andrews is one of two internal coaching hires made thus far. Next season will mark Andrews' sixth year with the Pirates organization, after he spent the last two seasons as the pitching coach for Triple-A Indianapolis and served in the same capacity for Double-A Altoona from 2003-05.

As a result of Andrews' five-year tenure in the organization, he has worked with a number of the young pitchers on the Pirates' staff, something that made Andrews such an intriguing candidate for the position. The 48-year-old Andrews helped develop four of the Pirates' five expected starters -- Tom Gorzelanny, Ian Snell, Paul Maholm and Zach Duke -- as well as a number of the team's young relievers.

"We are pleased to add Jeff to our Major League staff as pitching coach and are looking forward to watching him continue to positively impact the development of our pitching staff," general manager Neal Huntington said in a statement released on Wednesday. "In addition to having a familiarity with a number of our quality young pitchers from working with them in the past, Jeff brings quality experience, knowledge, passion and an ability to teach to our Major League staff."

Having been a Minor League pitching coach for the eight seasons, Andrews will now get his first taste of doing so in the big leagues. Previous to working within the Pirates organization, he split 16 years as a Minor League pitching coach or coordinator with Florida, San Diego, Seattle and Texas.

Andrews is the fourth coach to be named to Russell's staff in the last two days, joining Tony Beasley (third-base coach), Gary Varsho (bench coach) and Luis Dorante (bullpen coach).

The Pirates still are without a hitting coach and first-base coach, though both of those announcements are expected to come soon after the Thanksgiving holiday.
