Ok, here is the video footage of what occurred.

End of the 9th. Jose Cotto was already reluctant to go to his corner and Evangelista has the sponge ready. We don't get to see Evangelista throwing the water but we do see Jose going off to the other side of the ring. Once he comes back, shiet hit's the fan.
