Thieves broke into Knottingley Town Cricket Club and stole more than £2,000 worth of equipment.
Two generators and a scarifier were taken in the break-in at the club on Banks Garth earlier this month.
Colin Turner, the club’s media representative, said: “We’re going to struggle to find the money to replace the equipment. It’s going to have a devastating effect.
“We are trying to build the club up in the community and when something like this happens it’s really disappointing.
“We set up a junior team for the under-15s last year and there are a lot of people working really hard to make the club successful.”
Thieves targeted the club over a series of nights between November 26 and December 3.
Mr Turner added: “The problem we have is that, like most cricket clubs, we are isolated and therefore an easy target for thieves.
“Incidents like this can have a big effect on a club of our size.
“If we don’t manage to replace the equipment by the time the season starts in April we will be struggling to get the pitches ready.
“De Lacy Academy uses our pitch as well for their games, so it could affect youngsters at the school as well.”
Insp Geoff Carter, of Pontefract and Knottingley neighbourhood policing team (NPT), appealed for anyone with any information to get in touch.
Insp Carter said: “Knottingley Town Cricket Club is a great local facility for local people and offers people across the town the chance to get involved in the sport.
“This kind of crime can have a serious effect on sports clubs like this.
“I would urge anyone with any information to get in touch with the police by calling 101 or Crimestoppers on 0800 555111.”
