The Reds didn’t sit on their collective hands after a 97-win season. They addressed the big weakness – the leadoff spot in the batting order – and they tried to make a good rotation better. But to accomplish those goals, they took an unconventional route. The new leadoff hitter, Shin-Soo Choo, is going to have to play center field. He’s played one game there since 2006. And for the rotation move to work, Aroldis Chapman is going to transition from throwing one inning to six or seven on a regular basis. The two big moves start to take effect Tuesday when pitchers and catchers report to Goodyear, Ariz., for the official opening of spring training.
