Willson Contreras pulled up lame while trying to beat out a grounder in the 8th inning, eventually requiring assistance to make it off the field. It was pretty obviously a hamstring injury, though the severity is not known at this point. Even a relatively mild strain can keep someone out for a couple weeks and a more serious pull or tear can require 6-8 weeks on the shelf. Which puts us into October. Ugh.
I don’t want to speculate, but this did not look like the kind of deal that you rub down with Tiger Balm, wrap an ace bandage on, and call it a day.
