Dr. Wagner
The first of the double-main event of Triplemanía XVII was the AAA Mega Championship "dream match" as El Mesías defended the championship against Dr. Wagner Jr. While the crowd responded largely positively to El Mesías as he came to the ring the response to Dr. Wagner Jr. was overwhelmingly supportive, especially as Dr. Wagner Jr.'s ring gear and mask was patterned on the Mexican flag, invoking a feeling of national pride in the fans. The match started out cleanly with the two wrestlers exchanging moves and holds. The initial part of the match was centered around the respect each wrestler clearly had for the other. After a while El Mesías began wrestling a more "rudo" style, a bit rougher in the ring with more brawling than wrestling as a response to the crowd being mainly behind Dr. Wagner Jr. Once El Mesías began working as a "rudo" he took more control of the match, tearing Dr. Wagner Jr.'s mask open and later on drawing blood from the Doctor. Wagner responded in kind and before the match was over both wrestlers bled profusely from their foreheads. The match went almost 40 minutes in total and saw both competitors fight inside and outside of the ring in a very competitive, energetic match. El Mesías almost won the match when he slammed Dr. Wagner Jr. through a table on the outside of the ring, but the Doctor made a last second recovery and entered the ring before the count of 20. Dr. Wagner Jr. was finally able to capitalize on a mistake by El Mesías and executed not one, but two Wagner Drivers on El Mesías and pinned him. The crowd roared in approval as Dr. Wagner Jr. was announced as the new Mega Champion, especially when he struck his trademark kneeling pose in the middle of the ring.
