SAN FRANCISCO (AP) — Water the field less frequently. Let seats get a little sticky. Monitor the moisture in the grass.

California’s ballparks are experimenting with all sorts of different ways to cut back on water use amid the state’s historic drought.

At AT&T Park, the grass is a constant project for head groundskeeper Greg Elliott. He’s watching carefully for days when he can cut back on overnight watering on the field where the World Series champion San Francisco Giants play.

The ballpark also is considering asking fans to clean up their own soda spills, after already deciding to power-wash every other game. At Petco Park, the Padres say they conserved approximately 288,000 gallons of water during the offseason by not maintaining the playing field grass.
