sun could absolutely be a factor. take the same situation as in game 5, but make it a day game with a bright sun. ball goes up above F4's position and should be a "routine" catch, but he looks up and right into the sun, causing him to move his head away and put his arms up over his head for protection. reading this reaction of the fielder, you no longer have a catch that is about to be made with ordinary effort, you have a fielder that doesn't know where the ball is. you're telling me you're going to call infield fly on that?
