Contreras will start in left field and bat cleanup Friday against the Pirates.
Friday's start in the No. 4 spot will be the ninth for Contreras, and it will be his ninth start in left field as well. The 24-year-old is now batting a ridiculous .319/.397/.623 through 78 plate appearances, doing similar damage against both handedness of pitcher. It seems he's firmly locked into the heart of the Cubs' order.
