Kacy Esther Catanzaro

Kacy Catanzaro is an American professional wrestler, gymnast and athletics-based television personality. She is signed to WWE, where she competes on the NXT brand. She was the first woman to qualify for the finals of the television sports show American Ninja Warrior and the first woman to complete a City Finals course. Born in Glen Ridge, New Jersey, Catanzaro grew up and attended high school in nearby Belleville and is of Italian descent. She is a small woman, standing only 5 ft (1.524 m) tall and weighing only 95 pounds (43 kg). She began doing gymnastics at age 5. She attended Towson University in Towson, Maryland, from 2009 until 2012, studying early childhood education on an athletic scholarship. Catanzaro was a Junior Olympic gymnast, having started training at age 6. She reached level 10 in 2007 and competed at the 2007 New Jersey Level 10 State Championships where she placed fifth in the Senior-A division. The following year Catanzaro competed at the 2008 New Jersey Level 10 State Championships where she placed third and advanced to the 2008 Junior Olympic National Championships. She finished 23rd overall but finished 6th on the uneven bars. he worked for Alpha Warrior, an obstacle-course gym in San Antonio, Texas, from February 2013.

Catanzaro spent two years training for American Ninja Warrior alongside her then-boyfriend and co-competitor Brent Steffensen. She did not complete the qualifying course in Venice, California, but was an invited wild card at the 2013 finals, where she fell early on the Giant cycle/ring.

In 2014, Catanzaro became the first woman to complete the qualifying course of American Ninja Warrior (Season 6), making it up the warped wall on her second try at 5:26.18 at the Dallas qualifiers, ranking her 21 out of 30; this also makes her the first woman to make it up the warped wall in competition. Later in 2014, Catanzaro competed in the Dallas finals of American Ninja Warrior. She was the first woman ever to complete a city finals course (and the second woman to attempt it after Jessie Graff in season 5), qualifying for the national finals in Las Vegas with a time of 8 minutes, 59 seconds. (Through 2017 she remains the only woman to have ever completed a City Finals course.) Host commentator Akbar Gbaja-Biamila remarked "I've seen greatness during my NFL career...And I've been in awe of people, but I am really in awe of Kacy" The run had been especially notable because due to her short stature, many of the obstacles looked difficult to manage and in one case, she had to leap between boards whereas other competitors could traverse them. Her achievement made her a social media phenomenon, with her run being viewed over 100 million times; supporters on Twitter coined the hashtag #MightyKacy. Kacy Catanzaro failed to complete the first round of the National Finals in Las Vegas. She made it past the first three obstacles, including the Giant Ring and the Silk Slider, before she fell attempting the Jumping Spider, where her full extension was simply too short to hold the position. In the 2015 Houston Qualifying round (Season 7), Catanzaro failed to complete the course after falling on the cargo crossing. She was given a wild card spot in Vegas and she failed due to a mistimed trampoline jump at the Propeller Bar at Stage 1 of The Finals on September 7. By this time the pressure she felt to live up to her broadcast reputation as Ninja's greatest female competitor was reportedly showing and she was tearful in the post-run interview. In 2016, Catanzaro was invited to compete in the 32nd competition of the original Japanese version of ANW, Sasuke. Catanzaro performed well, completing 8 of the stage 1 obstacles before timing out on the final obstacle, the Lumberjack Climb. Since the course's renewal and increased difficulty, Catanzaro set the record for the furthest a female athlete has gone and the closest a female athlete has gotten to completing stage 1 since the 2nd competition (until 2017 when Jessie Graff completed stage 1 and became the first woman ever to complete stage 2.) In the 2016 Oklahoma City Qualifying round (Season 8), Catanzaro failed to complete the course after falling on an early obstacle, the Log Runner, on June 20; however, she was again given a Wild Card spot in Las Vegas. In the Las Vegas National Finals, Stage 1, she fell on the second obstacle. In December 2016 Catanzaro co-hosted as a broadcaster the Team Ninja Warrior College Madness series of shows. In 2017, Catanzaro competed in American Ninja Warrior season 9 in the San Antonio city qualifier and finals. In the former she failed on the fourth obstacle, but did well enough to qualify for city finals under the show's new rules. In that latter run she had her best performance since 2014, making it past the Sky Hooks and the fifth obstacle to get the now-higher Warped Wall, which she failed to surmount. Nonetheless she qualified for the national finals. At the national finals, she failed on Stage 1 at the Double Dipper.

In 2017, Catanzaro announced her retirement from American Ninja Warrior, with season 9 being her last.
