Nick Swartz, the Royals’ head trainer for the last 19 years, will retire at the end of the season.
The move was announced before Friday’s game against the Twins.
In a prepared statement, Swartz said he wanted to spend time at home and “enjoy life outside” of baseball.
“It’s been a great run and something I have been blessed with the good fortune or doing what I aspired to do from the first day I entered college,” Swartz said. “But I realized in the last few weeks that it was time for me to step away.”
Swartz joined the Royals’ organization in 1977, making his way to the big-league team in 1989. He was part of two All-Star staffs (1996 and 2006).
This season, in particular, he came under criticism from fans and some media for the treatment of some players — mostly pitchers.
In a statement released by the team, general manager Dayton Moore said he tried to talk Swartz out of retirement, called him “a tremendous asset” to the Royals, and wished him well.
