I am not certain who they were, as I am not a National League Baseball fan, but for years, the Cardinals of St. Louis had a terrific DP combination. Although, I think they were the Kings not Queens of DP.
Of course, in the American League, it has been the Yankees who have traditionally had a strong DP combination. Not sure who my favorite "DP"er combo is for that team, but I sure do enjoy watching the action. Those boys are good ... damn good!
