In late 1994, Sunny was contacted by the WWF, and she began appearing as Tamara Murphy, a commentator for "Live Event News" segments during syndicated WWF television shows. One month later, Chris Candido joined the WWF, and the duo began appearing as Sunny and Skip, known collectively as the villainous fitness fanatics, The Bodydonnas. Zip later joined the team, and Sunny was in their corner when they won the Tag Team Championship over The Godwinns at WrestleMania XII. Weeks later, The Godwinns regained the championship, and Sunny turned on The Bodydonnas in favor of the new champions. She then turned on The Godwinns and helped The Smoking Gunns win the Tag Team Championship. After The Smokin' Gunns lost the title at In Your House 10: Mind Games, she fired them in the middle of the ring.
She spent a short time as the manager of Faarooq Asaad, aiding him in his feud over the Intercontinental Championship with Marc Mero and his valet Sable. Sunny then began acting as host for several WWF television shows, including LiveWire and Shotgun Saturday Night. In August 1997, she made a special appearance at ECW's Hardcore Heaven 1997 pay-per-view.
In 1998, Sunny became a face and briefly became the manager for the Legion of Doom 2000, leading them to a win in a Tag Team Championship number one contender battle royal at WrestleMania XIV. Sunny would continue to manage them until she was released in July 1998.
After being released by the WWF in July 1998, Sunny joined Extreme Championship Wrestling (ECW). She made her debut at Heat Wave four days after her WWF release. Now billed as Tammy Lynn Sytch, she assisted Candido in his win over Lance Storm and their subsequent feud. By September, Storm introduced his own valet, a parody of Sytch, "Tammy Lynn Bytch", (later known as Dawn Marie). Later that year, Sytch and Candido took some time off of television.
When the duo returned, Candido re-aligned with Shane Douglas' Triple Threat, and Sytch began a feud with Douglas's manager Francine. She returned in October 1999 on an episode of ECW on TNN. After a brief feud with Dawn Marie, Candido and Sytch left the promotion in December 1999.
In 2000, both Sytch and Candido signed on with World Championship Wrestling (WCW). Candido debuted in March of that year and Sytch debuted one month later at Spring Stampede, helping him win the WCW Cruiserweight Championship in a match against The Artist Formerly Known as Prince Iaukea. She then feuded with Iaukea's valet Paisley. The short-lived feud came to a conclusion at Slamboree when The Artist and Paisley stripped Tammy's dress off to reveal her undergarments following Candido's singles victory over Iaukea. Sytch and Candido then briefly feuded with Crowbar and Daffney. Candido later dropped the title, which marked the end of the couple's run with the company.
In 2007, Sunny made an appearance on the 15th Anniversary of Raw. She also participated at WrestleMania XXV on April 5, 2009 in the 25-Diva battle royal for the crown of "Miss WrestleMania" but was eliminated by Beth Phoenix. Sunny was inducted into the WWE Hall of Fame by the entire roster of WWE Divas on April 2, 2011.
