The mean number of home runs hit by these players is calculated by finding the total number of home runs and dividing that number by the total number of players. From the graph, we get that there is a total of $$6\cdot 6+7\cdot 4+8\cdot 3+10=98$$ home runs among the top 14 hitters. Therefore, the mean number of home runs hit by these players is $$\frac{98}{14}=\boxed{7}.$$
