Scarab: Strategus or Xyloryctes

Whats this bug?
My dogs went crazy when they saw this "little" guy flopping around on the porch. I’ve attached 2 pictures. I live in San Antonio, TX

Hi Christie,
We wanted to be more accurate with your scarab beetle, so we contacted Eric Eaton. He narrowed it down to two possible genuses. Here is what he has to say: “I’d suspect Strategus or Xyloryctes before Dynastes. The thorax of this specimen appears at least slightly concave, whereas in Dynastes it is smoothly convex. I’d probably have to compare the specimen to known specimens before I could ID conclusively, but can pretty much rule out Dynastes. Eric “
