Perkins appeared on the October 19, 2009, episode of Raw; he was scheduled to face The Miz but was replaced by Marty Jannetty before the match as a part of the storyline. The following day Perkins, under the name J.T. Quinn, appeared on ECW in a match against Sheamus. The match resulted in a disqualification after Shelton Benjamin attacked Sheamus. He also wrestled at Florida Championship Wrestling, WWE's developmental territory multiple times that year. On May 7, 2016, Perkins defeated Fred Yehi at Evolve 61 to qualify for WWE's Cruiserweight Classic tournament. In the tournament he defeated Da Mack in the first round, Johnny Gargano in the second round, Rich Swann in the quarter finals, Kota Ibushi in the semifinals and Gran Metalik in the finals to win the tournament and become the inaugural WWE Cruiserweight Champion. His entrance paid homage to the Nintendo Entertainment System. Perkins retained the title against Brian Kendrick at Clash of Champions, but lost the title in a rematch at Hell in a Cell after Kendrick faked a knee injury. At Roadblock: End of the Line, Perkins failed to regain the title in a triple threat match against Kendrick and new champion, Rich Swann. Beginning with an attack on Austin Aries on the April 10, 2017 episode of Raw, Perkins formed an alliance with Neville and turned heel, shortening his ring name to "TJP". The alliance ended when Neville attacked TJP on the June 5 episode of Raw. TJP failed to win the Cruiserweight Championship the following night on 205 Live and then took a hiatus in order to rehab his knee. TJP returned on the January 2, 2018 episode of 205 Live. At Royal Rumble, he teamed with Drew Gulak and Jack Gallagher in a losing effort against Gran Metalik, Kalisto and Lince Dorado. On the January 30 episode of 205 Live, TJP defeated Tyler Bate in the first round of the WWE Cruiserweight Championship tournament. He would go on to face eventual winner Cedric Alexander in the quarterfinals on the February 27 episode in a losing effort. TJP appeared again on September 4, challenging Cruiserweight Champion Cedric Alexander in a non-title losing effort. TJP then began feuding with the Lucha House Party, consisting of Kalisto, Metalik and Dorado, forming an alliance with Mike and Maria Kanellis. In February 2019, TJP took part in the Worlds Collide tournament, but was eliminated by Dominik Dijakovic
