In the first game, Grant Hougue apparently beat out a throw at first by two steps and was called out. Polk argued and was ejected. (Legit)
In the second game, Polk was ejected for arguing balls and strikes. (This is the one I question)
In the third game, apparently a batter leaned into a pitch that was in the strike zone and was awarded first base. Polk argued and was ejected. Then for some reason the umpire decided to reverse his decision and called the batter back and then Cohen argued and was ejected. (Legit)
