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.
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.
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.
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.
