Washington Nationals rookie outfielder Dylan Crews will get an MRI on his sore lower left side and back after leaving Tuesday night’s 5-3 win over Atlanta in the sixth inning.

Having Crews in the lineup helps spread the left-handed hitters out more, making it harder for opposing managers to navigate through the later innings with their bullpen. Without Crews, expect the team to see a plethora of hard-throwing lefty relievers early and often.
