The Yankees have an extreme stadium when it comes to home runs, a fact everyone knows. Even with this knowledge, the team's roster construction doesn't gain too much of a home field advantage.
One of the most unique aspects of baseball that isn't seen in any other sport is the individuality of venues. Each and every team's stadium features different dimensions, climates, and park factors that can change the way baseball is played. A game in San Diego is drastically different from one in Colorado, and home teams can construct their rosters to best fit their home parks.
