For a bonus gold star: Name the other 11 without looking it up. There is at least one for each position other than DH.
Ok here goes:
1. Pujols-1B
2. Bonds-LF
3. Murphy-CF
4. Schmidt-3B
5. Morgan-2B
6. Mantle-CF
7. Maris-RF
8. Berra-C
Damn. Have to look the rest up.
Not bad... consider half a gold star officially awarded.

C: Yogi Berra
1B: Frank Thomas, Albert Pujols, Jimmie Foxx
2B: Joe Morgan
3B: Mike Schmidt
