Zduriencik began remodeling the franchise Tuesday, firing scouting director Bob Fontaine and hiring a pair of former colleagues from Milwaukee.
Tony Blengino and Tom McNamara will join Seattle's staff after working with Zduriencik in Milwaukee.
"The process of reorganizing the Mariners baseball operations staff is ongoing and will probably take at least another three weeks," Zduriencik said in a statement. "As a part of that process, I am excited to be able to add individuals the caliber of Tony and Tom to our staff."
Zduriencik added that exact titles for Blengino and McNamara will be determined as the department's structure is finalized.
The team also announced that Lee Pelekoudas and Bob Engle will remain with the club. Pelekoudas served as interim general manager following the firing of Bill Bavasi in June. He interviewed for the permanent job after the season, but was not among the final four candidates brought back for a second interview.
Engle is the head of Seattle's international scouting department.
Blengino spent the last six seasons with Milwaukee, and was the assistant scouting director under Zduriencik for the last three years. Before joining the Brewers, Blengino was an accountant and served as the Chief Financial Officer of the National Kidney Foundation of Delaware Valley in Philadelphia.
McNamara worked as a scout for the Mariners from 1994-2000. He moved on to Milwaukee where he was responsible for scouting and signing Prince Fielder. After a stint with San Diego, McNamara rejoined the Brewers in 2008.
Fontaine's firing was first reported in Tuesday's editions of The Seattle Times, citing unnamed sources. Fontaine came to Seattle with former general manager Bill Bavasi and served as the Mariners scouting director since being hired in December 2003. He previously worked with the Chicago White Sox, San Diego, Montreal and the Los Angeles Angels.
"As we move forward in was my determination that a leadership and direction change was necessary," Zduriencik said. "Bob is an outstanding person, and an outstanding professional. Decisions of this nature are never easy."
