It depends a bit on how you set up your game but what I would do is use an array and give my players a numbered instance variable (1 through to 11) and use that number to add stats to the index of that array (based on the players number).
For example, say player 11 catches someone out. You then add a point to the array at 11(x) and 1(y). If player 11 strikes out then you could add a point to 11(x) and 2(y) and so on.
Kind of sounds harder than it is but it is very effective.
