MLB trade rumors: Boston Red Sox linked to $13.25 Kansas City Royals All-Star ace ahead of deadline; Jarren Duran key trade asset?Boston Red Sox’s Jarren Duran (Image via Getty) The Boston Red Sox and Kansas City Royals are at the center of a growing trade rumor that has drawn attention across MLB circles. The idea is simple but significant: a straight swap sending Jarren Duran to Kansas City in exchange for left-handed pitcher Cole Ragans.Both teams are trying to solve clear problems. Boston needs another reliable arm at the top of its rotation. Kansas City needs a dependable everyday outfielder who can impact games on the bases and at the plate. This proposed deal addresses both without involving prospects or complex contracts.

How the Trade Would Work

The trade would be a one-for-one exchange. Boston sends Duran, who is arbitration-eligible and under team control through 2028. Kansas City sends Ragans, also controlled through 2028, with a salary path that stays manageable and peaks at $7.5 million in 2027. From a financial standpoint, the move fits both clubs. Boston adds pitching without tax concerns, while Kansas City gains a controllable position player without long-term risk.

Boston Red Sox’s Perspective

For the Boston Red Sox, the appeal is rotation stability. Ragans has shown frontline ability when healthy and would slot in behind Garrett Crochet and Sonny Gray. His strikeout rate stands out, even in a shortened 2025 season affected by injury. Trading Duran also helps Boston manage an outfield logjam, with younger options like Ceddanne Rafaela already in place and Roman Anthony nearing readiness.The concern is durability. Ragans dealt with rotator cuff and groin issues in 2025, which lowers the margin for error in a division as demanding as the AL East.

Kansas City Royals’ Perspective

The Kansas City Royals get a clear everyday center fielder. Duran brings speed, power, and flexibility in the lineup, and his presence would help lengthen the order around Bobby Witt Jr. Kansas City avoids sacrificing prospects and fills a long-standing outfield need.The downside is obvious. Ragans has shown the ability to miss bats at an elite level, and moving that kind of arm always carries long-term risk, especially for a team building around sustained contention.

Who Comes Out Ahead

If Ragans stays healthy, Boston likely gains more long-term value by strengthening its rotation. Kansas City gets immediate lineup help in a more forgiving division. The trade makes sense for both sides, with the Red Sox holding a slight edge due to positional impact.
