When the Cincinnati Reds claimed Micah Johnson, they added a left-handed hitting second baseman that can also play the outfield. This is similar to what the Reds did right before opening day 2017 with Scooter Gennett. They are both left-handed hitting second basemen with some MLB experience.
Johnson only played in eighteen games in 2017, while recovering from a wrist injury. He was a top prospect in the Chicago White Sox system before getting his best shot at playing with them. Johnson would likely play primarily at second for the Reds with their crowded outfield, but the flexibility is an added feature.
