Year four pupils at Churwell Primary School took part in a rounders tournament against other local schools.
The children played Morley Victoria, Asquith and Fountain Primary School as part of the TSC Aspire rounders tournament.
Churwell won all their games and came first in the competition.
A spokeswoman for the school said the children had spent their recent lunchtimes practicing for the day.
She said: “The children played really well as a team and were a credit to the school.”
