Alex Anthopoulos is leaving the Toronto Blue Jays less than a week after the American League East champions were eliminated from the post-season, rejecting an extension to remain as general manager, according to multiple sources. The stunning and franchise-altering departure comes with the looming arrival of Mark Shapiro, who was hired Aug. 31 and is scheduled to take the reins as president and CEO from Paul Beeston on Monday. While details are unclear at the moment, the issues leading to the split aren’t thought to be financial.
