"We believe that we need a new voice in the clubhouse," Mariners GM Jerry Dipoto said in a statement. "Dan knows our team and has been a key member of our organization working with players at every level over the past 11 years. He is well respected within and outside of our clubhouse and we are confident he will do a great job in leading our group over the final six weeks of the season and moving forward. I do want to thank Scott for all his efforts here in Seattle over the past nine seasons, He has poured his passion into the team and our community and I know I speak for the entire Mariners organization in thanking him for has hard work."
