When the LA Angels moves Taylor Ward from catcher to third base, he lost a lot of the value that made him a first round pick. A defense first catcher, they were seemingly taking away the best part of his game in hopes of it improving his offensive production.
They did just that, in a sense. Since his switch to third base (and the outfield/first base since then), Ward has seemed more adept at the plate. So while his value as a trade chip dropped, his hopes of becoming a contributor in the MLB rose.
However, as player after player was injured in Anaheim this season, Ward stayed comfortable in Salt Lake City.
