What happened: The right-hander is scheduled to undergo surgery Sept. 8 after multiple setbacks during his rehabilitation from a right rotator cuff strain. He has not pitched since March.
Why it matters: Estévez led MLB with 42 saves in 2025 while serving as Kansas City's closer. His contract includes a $2 million buyout if the club declines its 2027 option.
By the numbers: Estévez was placed on the injured list April 1 and transferred to the 60-day injured list June 15. He finished 2025 with 42 saves, the Major League lead.
What to watch: Kansas City will make its 2027 option decision during the offseason.
