Relentless rainfall in May meant TCU groundskeepers had to put in extra work to get Williams-Reilly Field in tip-top shape for this weekend’s NCAA regional baseball playoff, according to TCU groundskeepers.

Paul Holder, a TCU groundskeeper said the rain hasn’t affected the playing surface too much, though the crew used the infield tarp more than they would like to.

“If we cover up the infield too long, the infield grass will get yellow. We want to avoid that,” Holder said.

Holder said the shallow part of the outfield, around the warning track and the back of the infield are affected most. As a precaution, replacement dirt is kept on site if the surface becomes too wet. 

That replacement dirt was used this week to repurpose the visitor’s bullpen. 

Ross Bailey, TCU’s associate director of athletics, said the infrastructure at Lupton Stadium helped prepare the playing surface for the first day of regionals.

“We have a great drainage system,” Bailey said. “As long as the water has a place to go, we should be good.”

Officials will keep a close eye on the weather this weekend. There’s a 70 percent chance of thunderstorms Saturday afternoon and a 20 percent chance by Saturday evening, according to the National Weather Service. 

Bailey said that once the game starts, it’s up to the umpires to determine if play should stop due to weather. He did not know what a potential makeup schedule would look like.

“It looks the rain should pass by noon tomorrow. I don’t expect it to be a problem,” Bailey said. “The main thing is to be safe.”

Stony Brook will play Sacred Heart at 2:30 p.m. tomorrow. TCU is set to host North Carolina State for the nightcap at 7 p.m.
