Prediction: Wilder will win by KO/TKO in the 7th to 9th round.

Ortiz is too old, too slow, is shorter with a shorter reach, and is an easy target because he doesn't have good footwork any more. Besides, Haymon's officials including the referee will be there to help Wilder if needed. I wouldn't be surprised if there's a too-quick stoppage in favor of the American.
