Pretend to be Delino DeShields the past 12 months.
He played well enough in 2017 for the Texas Rangers to be named the 2018 starting center fielder as soon as the season ended, yet the Rangers said that one of their off-season goals was to add a defensive-minded center fielder.
So, DeShields worked on a variety of things to become better defensively, just as he had in previous off-seasons. Lo and behold, the SABR (Society for American Baseball Research) Defensive Index rates DeShields as the top center fielder in the American League.
Great.
