Major League Baseball 2K10

This achievement unlocks after the All-Star game is played, not when it says you make the all-star game. I suggest that you attempt to get this achievement as a hitter, because if you are a pitcher, there is a glitch where sometimes you don't pitch in the all-star game, so you sim right past it and you won't get the achievement. So in summary, if you get the option to play the all-star game, you don't have to play it, but if you don't get the option, there is a glitch and you must wait until next season to try again.
