In tennis, a Breadstick refers to a set that ends with a score of 6-1.
The term comes from the shape of the number one, which resembles a long, thin breadstick. A player who wins a set 6-1 is said to have "Served a Breadstick" to their opponent. Breadstick is less severe than a bagel (6-0 sets) but still indicates a dominant performance.
Top players like Novak Djokovic and Serena Williams have served many breadsticks in their careers.
Winning two sets 6-1, 6-1 is called a "Double Breadstick." Breadsticks can happen in any tennis match, from amateur to professional levels.
