Joseph Rosello is a firefighter and six-time competitor on American Ninja Warrior.
American Ninja Warrior 3[]
Rosello debuted at the Venice Qualifiers in season three. His run was all cut and he failed the Jump Hang. Rosello got a good bounce from the trampoline but couldn't hold on to the net.
American Ninja Warrior 4[]
Rosello's sophomore season began at the Southeast Qualifiers held in Miami. His run was all cut. Rosello was able to get revenge on the Jump Hang, but couldn't land the leap to the first ring of the Swing Circle.
American Ninja Warrior 5[]
Rosello competed as a walk-on at the Miami Qualifiers. It would be this run where Rosello would receive his first time on television, coming from a digest reel. Rosello cleared the qualifiers for the first time in his career. His finish time was 2:13:73 which was good enough for 11th overall.
In the City Finals, Rosello's run was shown in full knowing that Vegas would be determined on who got to the Salmon Ladder the quickest, Rosello went through the first half of the course much faster. He cut over 50 seconds from his qualifying time. His attempt of the Salmon Ladder didn't last very long. Rosello botched the jump up to the bar, falling into the water below. Due to his speed this performance was enough to qualify for Vegas. He placed 13th overall.
In Vegas, Rosello's Stage One run was shown in full. Rosello quickly made his way through the first half of the course. It was all going well up until the Half Pipe Attack. Rosello lunged for the rope but got a low grab. This caused his foot to tap the water, ending his season.
American Ninja Warrior 6[]
Like last year, Rosello had once again walked on in Miami. His qualifying run was cut, but he once again cleared the qualifiers. His time of 1:16:95 was enough for 6th overall.
In the City Finals, Rosello's run was digested. Rosello ran in a slower pace than he had in qualifying to conserve his energy. This strategy paid off, as he was able to get revenge on the Salmon Ladder. His run soon ended after on the Minefield when he got hung up on the holds. Despite running slower than the night prior, Rosello still clinched a spot in Vegas, placing 13th overall.
After placing 13th overall for the second year in a row, Rosello headed to Vegas once more. His Stage One run was all cut. Frustratingly, Rosello's second attempt at Stage One was worse than his first. Rosello's run was ended on the Silk Slider after he slid off the wet landing platform. This would be his last appearance in the National Finals.
American Ninja Warrior 8[]
After not being able to walk-on for season seven, Rosello successfully walked on at the Atlanta Qualifiers. His run was all cut and he was disqualified on the Spin Cycle. The Spin Cycle has a rule against using the support truss to aid in your dismount from the obstacle. Rosello had grabbed the truss on his way off the obstacle, disqualifying him from the competition. Had Rosello not made the contact, his time to the Pipefitter would've been fast enough to grant him a trip to the City Finals.
American Ninja Warrior 9[]
Rosello's final appearance in the series came at the Daytona Beach Qualifiers. This was Rosello's fourth time successfully walking on to the show. His run was all cut and he had failed the Wingnuts. This would be his worst result to date and he hasn't returned since.
