CLEARWATER, Fla. — Detroit Tigers pitcher Jordan Zimmermann has been working this spring training on two things: First, his slider.
When he arrived in Tiger Town this winter, his bread-and-butter breaking ball was flat, lacking much depth or movement. He moved his fingers around, taking his pointer finger off the seam, and found his pitch again.
Second, his mechanics were a little out of whack. His arms and legs weren’t raising at the same time, throwing off his timing.
