Perez agreed to a five-year, $52.5 million contract extension with the Royals on Tuesday, Jon Heyman of CBS Sports reports.
The new contract overrides the previous deal Perez signed with the Royals in 2012 -- a very team-friendly pact -- and locks him up through 2021. His offensive performance slipped the last couple seasons, but he played in an average of 143 games over the last three years and figures to remain a workhorse behind the plate in 2016.
