Q: How is the field surface constructed, and are there special or "hidden" features to help manage irrigation or maintenance?
A: The Giants field uses a base layer of pea gravel, then 12 inches of USGA-specified sand then the sod layer. A special SubAir system connects to the drainage system and can pressurize the field to cool it down and vacuum the field during rain situations. Toro field sensors, connected to the SubAir system, monitor moisture, temperature and salinity. Future plans include connecting those systems to the automated-irrigation clock.

Q: What steps go into making the field game-ready?
A: The San Francisco crew follows a "70/30" philosophy, dividing up the concentrations of work depending on whether the team is at home or on the road. When the Giants are in town, 70 percent of time and effort is spent working the clayed surfaces and 30 percent maintaining the grass. When the team is on the road, the percentages are reversed, with 30 percent effort spent on the clayed surfaces and 70 percent on the grass.
