“We had a number of guys mentioned throughout the season as candidates for this award, which is gratifying for us as a coaching staff,” White Sox manager Robin Ventura said in a statement. “Adam is one of the best clubhouse guys I have been around, and it’s nice to see that his hard work paid off. He is deserving of the honor.”
