I am not 100% sure but I think ryp is left handed.
I think he is right, I know this year he has been showing more left though due to a right wrist/thumb injury. He got the match penalty vs janssen because of tape on his hand, and if u watch the video u can tell he is throwing only lefts.
Brad Staubitz is a lefty. If you watch many of his fights, he looks like he is setting up at the beginning of a fight to throw rights, but then either switches just before starting or just after. Just ask Tootoo.
