I don't think it would be that easy for Yammy, though he has energy projection and arguably better physical strength, Odz has the agility and speed of Luffy and was able to not only dodge but also blitz Zoro and Sanji.
Oz should be faster but that might be it. Also assuming he gets the full shadow power he's psuedo immortal. However he can be beaten to the point of being paralyzed. I don't think it's so easy actually, but I think Yammy can take a win (for once).
