Rookie right-hander JT Brubaker will take the mound for the Pirates as they wrap up their three-game series against the Cubs this afternoon at PNC Park. Brubaker seems to be settling into a starting role, as he has recorded 12 strikeouts while giving up only four runs in nine innings over his last two starts. Right-hander Alec Mills will start for Chicago. First pitch is set for 1:35 p.m. ET, live on MLB.TV.
