<player preferred_name="Geraldo" first_name="Geraldo" last_name="Perdomo" jersey_number="2" id="ad64c80d-35f2-4d73-a027-d10362eef962" full_name="Geraldo Perdomo" status="A" position="IF" primary_position="SS">
<qualifiers>
<hitting AL="false" MLB="true" NL="true"/>
<pitching AL="false" MLB="false" NL="false"/>
</qualifiers>⭐ Benefit
With this update, you can easily determine whether a hitter or pitcher has enough appearances in a season to qualify as a statistical league leader. Keep tabs on these boolean values during the season as players become eligible or lose their eligibility.
League Leader Eligibility is defined as:
- Batter Qualifier - 3.1 Plate Appearances (PA) per team game
- Pitcher Qualifier - 1.0 Innings Pitched (IP) per team game
