Ketel Marte now controls whether the Diamondbacks can move him. After reaching 10-and-5 status in April 2026, the three-time All-Star gained full no-trade protection, which means any trade can happen only if Marte agrees to it.
That matters now because the search around Ketel Marte Trade Rumors For Diamondbacks is not just about interest from other clubs. It is about whether Arizona can even explore a deal without the second baseman’s approval, and that question has gotten louder as his relationship with the Diamondbacks has frayed over missed games and communication.
Marte’s status changed back in April 2026 when he hit 10-and-5, the mark reached after 10 years of MLB service time and five years with one team. For the Diamondbacks, that is a hard boundary. No-trade protection is not a suggestion. It is a veto, and it gives Marte the final word if Arizona ever tries to move him.
The backdrop is not clean. Reports about the situation first surfaced in August 2025, after Marte was briefly placed on Arizona’s restricted list following the All-Star break. John Gambadoro of 98.7 Arizona Sports reported that Marte was actually on vacation in the Dominican Republic and was willing to miss a couple of games after the break. Nick Piecoro of the Arizona Republic later reported that Marte had asked for a day off in the final week of the 2024 season while the Diamondbacks were battling for a wild card slot.
By August, the concern had shifted from one isolated absence to a pattern. Manager Torey Lovullo said Marte’s missed games without informing the team had happened in each of the last four seasons. Marte was again placed on the restricted list after he did not show up for a game at Fenway Park in August 2026, then moved to the 10-day injured list a few days later with knee inflammation. He was activated 14 days after his initial placement on the restricted list.
After returning, Marte apologized to Lovullo and his teammates, but he also offered his own account of the Boston absence. He called it “a moment of frustration,” said he is not the kind of person who likes to talk when something is going on in his life, and added that he woke up in pain that morning and could not react. He also said no one made the decision for him, and that he was the one who chose not to show up.
Lovullo’s response showed how far the relationship had already slipped. He said Marte is “definitely a retreater when things are on his mind,” and added that when something does not go well, Marte retreats. The manager also said he would stop shielding him as much, saying the decisions now would be Marte’s to make on his own.
That is why the trade question matters today. Marte’s protection does not force the Diamondbacks to trade him, but it does mean they cannot move him without his say-so. And with the relationship strained, Arizona’s next step is not simply to find a buyer. It is to find out whether Marte would ever agree to walk away.
