The above is correct except in the contests league didn't matter. In one contest Ken Boyer (St. Louis Cardinals) faced Hank Aaron (Milwaukee Braves). In another Harmon Killebrew (Washington Senators) faced Mickey Mantle (NY Yankees). Also, the forth home run in a row was worth $500 and the fifth was worth $1000. Two batting practice pitchers used. They alternated innings and the one who threw the most pitches, which resulted in a home run, also got a bonus.
