San Diego Padres certainly did their homework
Before signing on to become a cornerstone piece for the San Diego Padres, Eric Hosmer spent seven seasons with the Kansas City Royals, winning the 2015 World Series over the New York Mets in five games.
During his tenure in one of the best baseball cities in America, Hosmer was, at times, one of the best players in all of MLB both offensively and defensively.
Though his defense never truly faltered, his offense, you could say, took a year or two off during his time in Royal blue.
Not to say that he had unbelievably awful seasons during his two true down-years, but they were no place near the heights he reached in previous and following seasons.
