Iran's tallest man, sitting volleyball player Morteza Mehrzadselakjani stands with teammates before a preliminary match against Ukraine Wednesday.
At eight feet one inch, Mehrzad is head and shoulders above his teammates and fellow Rio 2016 Paralympians.
Suffering from a rare condition caused by excess growth hormone, Mehrzad's right leg is six inches shorter than the left, making it difficult for him to walk.
But on the sitting volleyball court, Mehrzad's height gives him a distinct advantage.
Sitting down, his outstretched arms reach more than six feet from the ground.
Within two years time, Rezaeigarkani hopes he can "be the best."
The top-ranked Iranian sitting volleyball team has won five golds and two silvers in its seven Paralympic appearances.
