I remember this fight very well. Zamora was a killer in the ring. In 29 fights none of them were around for the final bell. So yes it was a big upset. Ring magazine picked Zamora to beat Zarate. Zarate was another killer in the ring but had some skills to go along with big power. Lujan was not on the same planet as these two. Yet he out boxed and out punch Zamora. He hurt Zamora again and again. I didn't know Zamora didn't train for this fight and it showed. The last 3 rounds Zamora was tired and his legs were shot. Never even saw Zamora tired in any fight.
