The XIX US Open had its first day this Saturday in Santa Cruz, California.
One of the most traditional events in the gentle art calendar, the US Open gathered over 600 athletes on day 1 alone.
Kids were the protagonists for the first half of the day, with fierce disputes in age divisions that ranged from ages 4 to 15 years old.
Later on, adults entered the mats with the blue belt and brown belt divisions.
Adam Dunkel was the standout with the brown belt open class title.
The US Open returns this Sunday, Oct. 26, with the black belt divisions.
