Caine Sinclair (ケイン・シンクレア) is a free runner, and former member of Team Tempest Free Running, who qualified for SASUKE 23 as the #6 qualifier through American Ninja Warrior, the United States' qualifying competition. In the tournament, he performed well. He struggled on the Jumping Spider as he had trouble getting his shoes to stick to the walls. He said that the obstacle was "90% arms". This cost him valuable time, as he reached the Tarzan Rope with only 14 seconds left. As he raced up the Rope Ladder, he was fighting against the clock. He had both feet on the platform when time expired. So far, he is the closest person in the Shin-SASUKE era to miss clearing the First Stage.
He went into American Ninja Warrior 2 as one of the favorite competitors. Caine completed the qualifying round in 14th place. In the Semi Finals he cleared the Soritatsu Kabe in 56.33 seconds, but he failed the Salmon Ladder. His performance in the semis wasn't enough.Sinclair then returned in American Ninja Warrior 3 and he completed the qualifiers, but he wasn't fast enough to make it into the Semis. In American Ninja Warrior 4 he failed the Soritatsu Kabe in the Qualifiers. However, his region had only 26 people finish the course and he made it through the Devil Steps in the fastest time therefore he made the Top 30. In the Southwest Finals, he failed at the Arm Rings and backflipped into the water when he lost his grip, which was not good enough to make the top 15.
