The Royals signed Craig Kimbrel to a Major League contract on August 9, giving Kansas City another veteran arm for a bullpen that has struggled all season. If Kimbrel gets into a game, it will make the Royals the 12th team of his 17 MLB seasons.
The move lands Kimbrel back in the search for a late-season role after a 2026 that already sent him through New York and Tampa. He signed a minor league deal with New York over the winter, had his contract selected in April, was designated for assignment in May and chose free agency rather than accept an outright assignment. Tampa picked him up quickly, but last weekend brought another designation, and now Kansas City is the next stop.
That makes the signing easy to understand and harder to dismiss. Kimbrel still owns 440 career saves, the fifth-highest total in big league history, and he was an All-Star as recently as 2023. But the results have thinned out. He has a 4.81 ERA over 33 2/3 combined innings with the Mets and Rays in 2026, and since Opening Day 2024 he has a 4.78 ERA over 98 innings with an 11.1% walk rate and a 22.2% strikeout rate. That strikeout rate is tracking toward the lowest of his 17 seasons.
The money says Kansas City is buying upside without much risk. Selecting Kimbrel's contract locked in a $2.5MM salary for 2026, and most of that remains the Mets' responsibility. The Royals and Rays have been on the hook for only a prorated portion of the MLB minimum while he has been in the majors, which is the kind of accounting that turns a former elite closer into a low-cost gamble.
What comes next is the only real unknown that matters here: when Kimbrel first takes the mound for the Royals. The signing gives Kansas City a chance to see whether there is still enough left in his arm to matter, and it does it without forcing the club to wait long for the answer.
