LOS ANGELES -- Don Mattingly said Tuesday night's 10-3 loss to the Cleveland Indians "just shows us that we've still got a lot to continue to work on." He mentioned a plethora of "teaching opportunities."Such opportunities probably include explaining to Dee Gordon that taking off from third base on a shallow fly ball to left with nobody out might not be the smartest base-running play and that attempting to swipe second with nobody out in the sixth with your team trailing by four also might not be the right call.
