The Mainz Athletics are promoting another prospect to the Baseball-Bundesliga roster for the 2012 season. The 17-year-old Moses Williams, who was on the preliminary roster of the German Junior National Team prior to the 2011 European Championship, was added and is supposed to make another step forward in his development. The outfielder batted .321/.486/.429 with ten runs and five RBI in 12 games in the second division in 2011.
