This is the tennis entry for Jakub Mensik: Singles for ATP Tour, age 20. It sits alongside 77 other player entries in the picks tool.

At 74, accessibility is unusually good for something scored this highly elsewhere. Cards like that don't stay accessible forever, which is the argument for looking now rather than later.

Card upside (88) sits above the breakout score (78), 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 4 tennis breakout picks scored here, its breakout of 78 ranks 3rd of 4, card upside 88 ranks 2nd, accessibility 74 ranks 3rd, and risk 50 is the 4th-lowest. The closest thing to it on the numbers is Iva Jovic, which scores 82 and 86 on the same two axes — if you're weighing one against the other, the difference is in the reasoning rather than the scores.

Two years gives the situation time to develop past its first impression, which is usually when the price is set by whoever shouted loudest. It also means two years of not touching it, including through the stretch where it looks wrong.

Risk at 50 is the middle of the range: real ways to fail, none of them exotic. A role change, a slow start, or the hobby simply deciding to care about something else for a while.

Where to buy Jakub Mensik

Walmart / TargetCard shopCard showOnline

You can realistically find Jakub Mensik cards at the card aisle at Walmart or Target, a local card shop, a card show and online.

The big-box card aisle is in play here, which mostly matters because it is the one place you can pay the sticker price instead of someone's asking price. Stock is erratic and restocks are usually early in the week.

Show tables and online listings are where individual cards change hands, so those two are always open to you. What varies is whether a shop or a retail pack is a sensible way in as well.

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.
