Watch: Fan light show fuels fantastic at-bat by Giants' Belt

Let there be light.

During Friday's contest between the San Francisco Giants and Colorado Rockies, fans at AT&T Park decided to try something new, lighting up their cell phones all over the park to support slugger Brandon Belt.

With the ballpark lit up like a Christmas tree, Belt lined an RBI single into center field during a 13-pitch at-bat and gave his team a 5-2 lead in an eventual 8-2 win.
