By the standards of their own recent history, the Royals had a very successful season. The team won 86 games, their best record since 1989, and they outscored their opponents on a season for the first time since 1991. Their two biggest offseason acquisitions, Ervin Santana (in a dump trade with the Angels) and James Shields (in the Wil Myers trade with Tampa Bay), both pitched very well for the big club, helping the Royals allow the fewest runs of any team in the American League, 23 fewer than the division-winning Tigers. Some young players took strides: Eric Hosmer hit .317/.365/.492 after the team fired hitting coach Jack Maloof; catcher Salvador Perez had his first full, healthy season in the majors and performed well.
There were plenty of positives for the Royals, but because the season went well, some of the structural reasons that helped the team get to this point will now work against the team.
