Toronto Blue Jays general manager Alex Anthopoulos has turned down a multiyear extension offer and is leaving the club, according to multiple reports.

The executive's contract was set to expire Saturday.

During his season-ending news conference Monday, Anthopoulos said he had "great discussions'' with incoming president Mark Shapiro.

Anthopoulos replaced J.P. Ricciardi as the Blue Jays' general manager in 2009.
