They should put sensor tags on each player's cap/uniform/shoes/whatever to track their exact positions on the field. Then, use the readings from that to generate a live view at the top of your screen of where all the fielders and runners are. This would be way cooler than the standard static image of the diamond, indicating which bases have runners on. Instead of just knowing that there's a runner on first, you could actually see how much of a lead he's taking, where the first-baseman is in relation to him, and what positions the outfielders are in for the person at bat.
