Mattingly has been there for 3 years, they won the division last year after increasing payroll from sub $100MM to over $200MM. They continued to poor money in to them, this year the highest payroll in MLB history. Betting odds preseason had them winning the WS and I'm certain the owners expected more than another division clinch. It wouldn't surprise me if they canned him for accountability since someone has to take blame and they sure won't put the loss on Kershaw.
