PHOENIX — Dave Roberts sounded like a professor teaching a class on the complexities of hitting.
The Dodgers’ manager used technical terms like “flexion,” “levers” and “barred out.” He dissected next-level batting nuances, from base width to hand placement to firing position at the start of each swing. He spent 10 minutes Saturday trying again to explain the continuing evolution of Cody Bellinger’s swing.
Roberts’ message to his uber-talented but ever-inconsistent center fielder, however, is much more simple.
