The McCourts get separated because Jamie is cheating with her bodyguard in fall of 2009. 12 months later, the post-nuptial agreement is invalidated by a judge. McCourt runs out of money and is unable to make payroll. MLB seized control from McCourt in April 2011. Great ownership, really.
"I have taken this action because of my deep concerns regarding the finances and operations of the Dodgers and to protect the best interests of the Club, its great fans and all of Major League Baseball. My office will continue its thorough investigation into the operations and finances of the Dodgers and related entities during the period of Mr. McCourt's ownership." - Bud Selig
Maybe the McCourts shouldn't have used the Dodgers as their personal credit card to fund their lavish lifestyle?
