David Saikin is a rock climber in Argentina who has won multiple rock climbing championships in that country.
David would be selected to represent Team Latin America on American Ninja Warrior: USA vs. The World 3. He would first run on Stage Two, where he spent more than 50 seconds on the Giant Ring Swing and fell immediately after completing the skyhook part of the obstacle, possibly due to not being able to absorb the impact as his grip was giving out. On Stage Three, David's inexperience would show once again as he could not swing properly on the Ultimate Cliffhanger and failed the sideways transition after clearing the first jump of the obstacle. He lost the heat to Stefano Ghisolfi as he cleared the Floating Boards slower.
