For the third straight game the Rockies will roll with the same lineup as the first two games. Wily Peralta, Milwaukee’s best pitcher in 2014, will oppose Eddie Butler. Colorado will be hard pressed to keep the offense humming on all cylinders against Peralta. They will need Butler to mix up his pitches with good command. Drew Creasman of Purple Row had an excellent article about what to watch for when Butler is on the mound. Naturally the goal is to stay competitive over six innings, but that is the big question as he has dealt with shoulder fatigue on and off since his debut in 2014. His most recent fatigue was in late spring so we have yet to see if he has been lengthened out. Christian Bergman is on the roster for that reason.
