Final answer:
Without specific data about the players' performance, it is not possible to accurately name the top three leading scorers or determine which baseball player had a higher batting average compared to his team.
Step-by-step explanation:
The question regarding Fredo and Karl who wanted to compare their batting averages is rooted in mathematics, particularly in the area of statistics. Unfortunately, the information provided does not contain any specific data related to Dickie, Henri, and Andy's scores or Fredo and Karl's batting averages. To determine who had the higher batting average, we would typically compare their individual averages to the team average, likely using a formula such as (player's hits/player's at-bats) / (team's hits/team's at-bats). Owing to the lack of accurate data for the players in the given question, I can't confidently provide the top three leading scorers for the season or determine which baseball player had the higher batting average relative to his team.
