SAN DIEGO -- A close call in the first six innings tonight could quickly shine a light on baseball's most radical rule change and the managers who are governed by it. Both teams will have access to the new instant-replay technology.The replay system was not available to the Dodgers and Arizona Diamondbacks when they played in Australia last weekend.The Dodgers were able to experiment with a cruder version of instant replay in spring training, and manager Don Mattingly said he feels comfortable with it going into Sunday's game.
