Smart field

WITH A $500 million slate of renovations on hold, 100-year-old Wrigley Field owns the dubious distinction of being the least tech-friendly MLB stadium. Whenever Wrigley's modernization does start, the Cubs can look to the Giants' AT&T Park, the most cutting-edge facility in baseball, for inspiration.

1. Field
The Giants' $450,000 SubAir field maintenance system, installed after the team won the 2010 World Series, uses satellites, surface sensors and underground vacuum channels to control moisture levels while using less water.

2. Facility
A league-leading 86 percent of waste is recycled instead of heading to a landfill. Automatic lighting, water conservation and a 123-kilowatt solar array made AT&T the first MLB stadium to earn a coveted LEED certification from 
the U.S. Green Building Council.

3. Fans
Behind the park's 103-by-31 1/2-foot Diamond Vision is @Cafe, home to the Giants' social media team during games. A 12-by-4-foot video wall displays real-time fan reaction from around the world. Phone-charging kiosks make @Cafe the place to grab a cup of coffee.
