Before the Cubs hosted the San Francisco Giants on Day 2 of American Legion Week, Willson Contreras was out in left field running and working out his injured right hamstring.

That was two-and-a-half weeks ago and the Cubs initially tabbed the Grade-2 hamstring strain as a roughly four-week timeline.
