Как сгладить массив массивов - но не полностью вниз

каков лучший способ конвертировать это

[[["Club three Team one", 7800], ["Club three Team two", 7801]], [], [["Club four Team one", 7807], ["Club four Team two", 7808]], []]

на 

[["Club three Team one", 7800], ["Club three Team two", 7801], ["Club four Team one", 7807], ["Club four Team two", 7808]]

в Ruby? расплющить преобразовывает это все, вплоть до 

["Club three Team one", 7303, "Club three Team two", 7304, "Club four Team one", 7310, "Club four Team two", 7311]

использовать flatten(1) http://apidock.com/ruby/Array/flatten

your_array = [[["Club three Team one", 7800], ["Club three Team two", 7801]], [], [["Club four Team one", 7807], ["Club four Team two", 7808]], []]
your_array.flatten(1)
#=> [["Club three Team one", 7800], ["Club three Team two", 7801], ["Club four Team one", 7807], ["Club four Team two", 7808]]
