Professional wrestling career Early career and tryouts Gargano made his professional wrestling debut for CAPW in 2005. In his first match, he competed in the AIW Gauntlet For The Gold Battle Royal on December 11, 2005, which was won by Michael Hutter. Gargano calls his wrestling style "Lucharesu", a mix of British chain wrestling, lucha libre and puroresu and described his character at the time as "someone lacking self awareness and living in his own deluded little world". On October 8, 2006, Gargano defeated Josh Prohibition, M-Dogg 20, and Zach Gowen in a four-way match to win his first Championship, the CAPW Junior Heavyweight Championship. He would continue to make appearances for the company until August 5, 2007, teaming up with Prohibition in his CAPW farewell match, where they defeated Alex Shelley and Chris Sabin. On June 24, 2009, Gargano wrestled in a dark match at Total Nonstop Action Wrestling's Impact! television tapings, losing to Jay Lethal. The following day he wrestled in another dark match, this time losing to Eric Young. Gargano has also wrestled in a dark match for Ring of Honor, defeating Sami Callihan on August 15, 2008. After his ROH tryout it was discovered that Gargano had a hairline fracture in his back, caused by his left leg being shorter than his right leg, which led to his doctor advising him to rethink his career choice. Gargano, however, returned to the ring six months later.
