Ketel Marte’s trade candidacy has become far more complicated because, after reaching 10-and-5 status in April, he gained full no-trade protection. That means any deal involving the Diamondbacks second baseman would now require his approval, a major factor as the relationship between Marte and the Diamondbacks has become increasingly strained.
The timing matters. Marte’s status changed in April 2026 after he reached 10 years of MLB service time and five years with one team, which gave him the full protection that comes with 10-and-5 rights. In practical terms, that gives him control over whether any trade can move forward, and it comes at a moment when the Diamondbacks have reasons to at least consider all options.
Why Marte’s protection changes the conversation
Marte is a three-time All-Star and one of the most recognizable names on the roster, but his situation is now about more than talent. The Diamondbacks cannot simply explore a deal and assume they can complete it. If Marte does not want to go, the process stops there.
That is why the latest trade chatter carries a different weight. The club’s ability to move him has been narrowed by a rule that gives him real leverage, and that leverage matters even more because the relationship between player and team has not exactly been smooth.
The strain between Marte and the Diamondbacks
The tension has been building for some time. Reports first surfaced in August 2025 about Marte missing games without informing the team, and after the All-Star break that year he was briefly placed on Arizona’s restricted list. Then, on 17 August, he did not show up for a game at Fenway Park.
A few days later, the Diamondbacks moved Marte to the 10-day injured list with knee inflammation. He was activated 14 days after his initial restricted-list placement, and after returning from the injured list he apologized to Torey Lovullo and teammates.
Lovullo has described Marte as someone who tends to retreat when things are difficult, saying that when something does not go well, “he retreats.” He also said the time had come to let players advocate for themselves rather than always being protected from the consequences of their own decisions.
Marte’s own explanation
Marte later framed the August absence as a “moment of frustration,” explaining that he does not like to talk when something is going on in his life. He said that morning his body was in pain and he could not react, adding that no one made the decision for him and that he chose not to show up.
That explanation does not erase the bigger issue for the Diamondbacks. Between the absences, the restricted-list stint, and the later injury designation, the relationship has clearly been tested. Now, with full no-trade protection in place, the club would need Marte to agree before any trade discussion could become something more concrete.
In other words, the Diamondbacks may still be able to discuss Marte’s future internally, but the final say is not theirs alone. His 10-and-5 status changed the terms of the conversation in April, and that makes any trade rumor far harder to turn into reality.
