    Position Confidence Scores

    Each player gets flexible developmental feedback with their best infield and outfield fits, confidence percentages, and short explanations for each recommendation.

    How suggestions work

    Defensive spots are assigned by matching each player's strongest confidence profile to each position. Shortstop, third base, second base, first base, catcher, center field, and corner outfield each use position-specific weights, then the top fits are shown for every player with a confidence percentage and explanation. League Type adapts the logic for T-Ball, Coach Pitch, Kid Pitch, or Travel Baseball play. T-Ball and Coach Pitch use a Pitcher's Helper instead of Pitcher on defense. Pitcher confidence prioritizes strike consistency first, then focus, velocity, and athleticism, and only players available to pitch today are considered for pitcher recommendations in Kid Pitch and Travel Baseball Mode. If 10 fielders are enabled, outfield recommendations use LF, LCF, RCF, and RF instead of LF, CF, and RF.
