Major League Baseball 2K10

There are 2 ways of obtaining hitter cards. You can either use the specific hitter or you can face the hitter. The easiest way to obtain these cards is to modify all of the hitters attributes to help or hinder the players performance depending on which team he is on.

While at the main menu, go to Features ->Trading Card Album to see all of the possible Cards. Collect 25 different ones and this achievement will unlock.

Chipper Jones is one of the cards you can unlock. You just need to collect 3 hits with him in a game.

You can also trade players to other teams to have more chances at getting cards and you start with a few cards already and these do count towards your achievement
