Japanese tennis sensation Shintaro Mochizuki has risen to number one in the international junior rankings after winning the boys' singles title at Wimbledon.
The International Tennis Federation released the junior world rankings on Monday.
The 16-year-old was in ninth place last week.
Mochizuki's victory at Wimbledon on Sunday came after his appearance in the semifinals of the junior boys' singles event at the French Open last month.
Mochizuki is the first Japanese junior tennis player to become the number one player in the world under the current ranking system.
