Corbin Carroll is one of 82 player entries in The Card Investor. Age 25, listed at OF, currently with Arizona Diamondbacks — filed under baseball.

Accessibility of 65 is what makes this interesting. The hobby hasn't priced the story in yet, and that is the only condition under which a high upside score is actually worth something to a buyer rather than to whoever already owns the cards.

Card upside (82) sits above the breakout score (74), which is the rarer shape. It means the cards look primed to react even though the step up in performance is less certain — usually because market size, playing style or an existing collector base is doing work the stat line isn't.

Set against the 14 baseball breakout picks scored here, its breakout of 74 ranks 8th of 14, card upside 82 ranks 8th, accessibility 65 ranks 3rd, and risk 32 is the 5th-lowest. The closest thing to it on the numbers is George Lombard Jr., which scores 82 and 88 on the same two axes — if you're weighing one against the other, the difference is in the reasoning rather than the scores.

The window is about six months. Long enough that one bad month doesn't settle it, short enough that you're betting on a specific stretch rather than a career. Six-month positions are where people most often forget they set a deadline.

Risk is scored 32, toward the low end of anything in the tool. Low risk in trading cards is still not low risk in any sense your bank would recognise — it means the identifiable ways for this to go wrong are fewer, not that they're absent.

How to read these four numbers

Every entry gets four separate scores instead of one grade, because a single grade hides the thing you needed. Full explanation in the guide: how to spot a breakout before the cards move.
