The Seattle Mariners got off to a fast start in the second game of the American League Championship Series against the Toronto Blue Jays on Monday, taking a 3-0 lead in the first inning.Mariners slugger Randy Arozarena was down 1-2 to open the inning against Blue Jays rookie Trey Yesavage. Arozarena looked at a slider from Yesavage and seemingly started walking thinking it was the third strike.However, the home plate umpire called it a ball, and the Mariners slugger got a life. He was hit by a pitch and was awarded first base. The controversial call eventually led to a bases-clearing home run from Julio Rodriguez.Fans reacted to the controversial strike call in the opening inning of Game 2."Then he scored off of the HR - this can’t happen in the playoffs.
