Four titles were on the line during the latest edition of WWE Saturday Night's Main Event. Both the Undisputed and World Heavyweight Championships were featured, with CM Punk claiming the vacant World Heavyweight Title.After attacking Tiffany Stratton and her leg over a week ago, Jade Cargill defeated Stratton for the WWE Women's Championship. Cody Rhodes retained his belt after dropping Drew McIntyre with a DDT onto the title belt.As has become the norm in his matches, Dominik Mysterio still managed to win by dirty means against Penta and Rusev. WWE made the next three mistakes at the latest edition of Saturday Night's Main Event.#3. Dominik Mysterio forgot how to cheat in a match with no rules View this post on Instagram Instagram PostThe entire emphasis of Dirty Dom's run in The Judgment Day and as the Intercontinental Champion has been cheating. He's beaten AJ Styles, Penta, Rusev, and others by doing whatever he could to keep his title.Without help from The Judgment Day members, he's cheated incessantly. Within the rules of a Triple Threat, however, cheating is technically legal, but Dom forgot that midway through his title defense.He grabbed a chair and tossed it to Rusev. Since anything was legal in their Saturday Night's Main Event match, The Bulgarian Brute simply blasted him with the chair. It was likely done for a moment of humor.Dirty Dom still hit the ring bell to distract Rusev despite the referee not ending the match. It lines up with his name, but devalues his opponents every time he cheats to win.#2. Penta lost to Dominik Mysterio yet againWhile Penta entered WWE with a lot of hype and excitement, all that goes away when he faces Dominik Mysterio. The former AEW star has been in and out of the Intercontinental Title scene since around WrestleMania.Penta did pin Dirty Dom right before The Showcase of the Immortals, but has been fodder for The Judgment Day member ever since.The luchador is 0-5 in title matches for the belt against Mysterio, including another loss at Saturday Night's Main Event. Penta wasn't pinned, but the loss to his rival still goes on his record.#1. The status quo with Cody Rhodes at Saturday Night's Main EventCody Rhodes is supposed to be WWE's biggest hero, and for the most part, he is. That still hasn't prevented him from resorting to heelish tactics to keep his title. He beat Kevin Owens once by DDTing him on the belt while the referee was down.The American Nightmare did the same to retain against McIntyre at Saturday Night's Main Event. This happened after the champion was intentionally disqualified by hitting The Scottish Warrior with the belt in front of the referee a few weeks back.Michael Cole claimed it was fine because Drew introduced the title at first, which he did. He's supposed to cheat because he's the heel. Wade Barrett explained that holding the belt isn't grounds for a disqualification unless he lands a blow with it.Bookers had a chance to do something different with the Undisputed WWE Title. Rhodes would have been protected if he had lost via countout or disqualification. It would have been something different, but now, Drew's claims are even more valid.
