Rodriguez made his debut in American Ninja Warrior 3, making it through the qualifying and semi-final rounds with little trouble and completed the Team Relays as one of the more consistent competitors on his team, the White Tigers. This consistency helped him become one of the ten U.S. competitors to qualify for SASUKE 27, with Rodriguez being the #5 qualifier. Although his First Stage run was digested during the NBC broadcast, his full run was shown during the SASUKE 27 broadcast. He was shown showboating on the course during his run, though this did little to hinder him and he was still able to clear Stage 1 with 17.73 seconds left on the clock. In the Second Stage, he failed the Slider Drop when he failed to keep the bar straight along the track, similar to what fellow freerunner and American veteran Levi Meeuwenberg did in SASUKE 25.

In American Ninja Warrior 4 Rodriguez managed to catch the fastest time in the Southeast qualifying round. He repeated his performance in the city finals round, knocking out Kamerion Wimbley. Overall, Rodriguez caught the fastest time in all 6 regions, earning him the prestigious #100 in the Vegas Finals. Rodriguez cleared Stage 1 with about 18 seconds left, but failed Stage 2 on the Balance Tank when he fell backwards and slipped off the tank.
In American Ninja Warrior 5 Rodriguez caught the second fastest time in both the Qualifying Round and City Finals in Miami. In Stage 1, he ran as #84 out of 85, but failed the Jumping Spider. When he came out of the water, during his interview, he was shown to be crying as he said he let all of the people who wanted him to win down.
In American Ninja Warrior 6 Rodriguez competed once again in Miami, but shocked many people when he failed the Jump Hang due to a rather controversial ruling where competitors are only allowed to go under the net as opposed to going either above or under it, not knowing how low he was near the water and lost his footing on the net, causing his rear to skim the water. This proved to be one of the most devastating moments of Rodriguez's life, as he felt far more devastated than in the previous season and even considered quitting for good. This is the only time Flip has failed a Qualifying Course.
After such a depressing previous two seasons, Rodriguez came back in American Ninja Warrior 7 stronger than ever due to the support of his fans. He finished the qualifying and landed in third place and for the first time he ran the course without his trademark mask which represented everything he went through the previous years. In the city finals, he maneuvered through the course with ease until he reached the Invisible Ladder. On the obstacle, he was moving through the obstacle at a steady pace but started getting fatigued. Inches to the finish, he tried to reach it with his legs but his grip gave out and failed. He still put up a strong performance and qualified to Vegas in third place. In Vegas, he got his revenge on the Jumping Spider and completed Stage 1 and later passed the fourth obstacle for the first time in Stage 2. On the brand new obstacle Roulette Row, Flip was able to transition to the second ring but didn't let go of the ring to land on the landing platform causing him to not gain momentum on the ring and ultimately falling in the water. American Ninja Warrior 7 is his best tournament to date.
Rodriguez came back stronger than ever and returned for American Ninja Warrior 8 at the Los Angeles Qualifying Round at Universal Studios, where he finished with the second fastest time at 02:23.12, advancing to the Los Angeles City Finals. During the Los Angeles City Finals he revealed more detail about his mask with the reason for wearing it was because he was sexually abused from the age of 9 to 15. During the Finals he put on an impressive run before failing at the new Wedge obstacle. Since he made it to the obstacle in a fast time he earned a spot for the Las Vegas Finals. Flip once again cleared Stage 1 with 4.78 seconds remaining. He failed the Second Stage's Wave Runner by dismounting from the first board, which was not allowed.
Rodriguez came back for American Ninja Warrior 9 competing in the Los Angeles Qualifying Round once again. While he took a more slow and steady approach to the course, it worked as he cleared with the 8th fastest time. In the city finals, he made it all the way to the new Elevator Climb obstacle but his strength gave out and he fell, but still qualified for Vegas in 5th place. Prior to the Vegas Finals, Rodriguez suffered from a hip injury. Despite this and his Stage 1 run being digested, he cleared with 30.66 seconds remaining.
