Mariners general manager Jack Zduriencik has been fired after seven seasons on the job, the team announced.

Zduriencik arrived in Seattle amid a lot of optimism in late 2008, as Mariners fans got excited about the notion of someone with a deep scouting background also (supposedly) having an analytics-friendly approach to decision-making. But the team simply never had any sustained success and many of Zduriencik’s moves were very questionable. He thrived at neither scouting nor analytics.

Overall the Mariners went 505-595 (.459) with Zduriencik as GM, including just two winning seasons and zero playoff appearances. Assistant general manager Jeff Kingston, whom Zduriencik hired in 2009, will take over the GM job for the remainder of the season.
