Looks projected to me... blow up the pic and you can see the green light in a cricle around the eye and around the spot on the ball as well... I'm guessing the eye and that spot on the ball both have a reflective coating of paint that makes it light up brighter when the light is projected down from the scoreboard above.
Seems more cost effective and logical to do it in that manner as well.
