This is a list of other players who hit with two hands on both forehand and backhand, rather than a list of evangelical Selesians! ;-)
I don't have time to go through every player profile on the WTA Tour and ATP Tour to find every last both-hands-ways player, so if you happen to know of any who are not listed here, please let me know.
