Barnes allowed a hit and a walk over two-thirds of an inning in Monday's 5-3 win over the Pirates.
Barnes was pretty good last season when inheriting runners, stranding 80 percent of the runners he faced -- the MLB average was 70 percent -- and he'll be used frequently to clean up starters' messes in 2017. However, he was unable to provide much help for Rick Porcello on Monday, letting both runners he inherited to come around and score.
