On August 5, the Chicago Cubs’ catcher Willson Contreras injured his right hamstring while running to first base after hitting a flyball. After taking several steps, he grabbed the back of his right leg and limped and hopped the rest of the way toward first base. An MRI was performed, something that is not likely to help with management and something that would not be considered for most hamstring injuries.  The Cubs estimated Contreras will miss four weeks.
