What did you miss on? I thought the 500 HR + 3000 hit parts were a breeze (A's 3k Hits - Henderson, SD 3k Hits - Gwynn, Orioles 500 HR - Frank Robinson, Twins 500 HR - Killebrew, 3000+ hits and 500+ hrs is pretty easy unless you assumed someone like Babe Ruth was in both (only 2800 hits). I went with Eddy Murray there).
I'm realizing that with the team squares, the answer either comes to me right away or I spent a crapload of time thinking of someone. I did Dave Winfield for Padres and Twins, but havent had a chance to go back and do the other 3.
