D-Backs second baseman Ketel Marte officially reached 10 years of major league service today. The three-time All-Star entered the season 10 days shy of that milestone.
It’s a significant achievement for any player. Marte’s impending 10-year milestone was more discussed than most because he found himself in trade rumors over the offseason. Players who have 10 years of service and have spent the past five seasons with one team automatically receive full no-trade protection under the collective bargaining agreement. Marte can no longer be traded by Arizona without his consent.
That doesn’t matter much in the short term. The D-Backs obviously weren’t trading Marte within the first couple months of the season either way. The front office ceased trade conversations about halfway through last offseason. General manager Mike Hazen has said a few times that talks never got especially close to a deal. He maintained throughout the winter that the front office didn’t want to move Marte but needed to consider all ways to improve their starting pitching.
If the Diamondbacks struggle this year, they could revisit the possibility at the deadline or next offseason. Marte turns 33 in October and is signed through 2031, albeit with an opt-out after the ’30 season. He’s still arguably the best second baseman in the league and is due below-market salaries for the next five years: $12MM in ’27, $20MM in ’28, $22MMM per season between 2029-30, and $11.5MM in ’31. He’d be a valuable trade chip if the D-Backs opt for any kind of retooling effort down the line.
Marte himself now has full control over his future. His contract had previously allowed him to block trades to five teams of his choice, which he could change each offseason. Marte said this evening that he thought he would be traded last offseason given all the rumors (video via Sports Illustrated), so he’s surely more comfortable now that the 10-and-5 rights are locked in.

This milestone doesn’t get the appreciation it should imo. It’s an incredible feat to accomplish. You not only have to be a good player but have to stay really good to even make it that long. He also gets full pension benefits.
Wise words from a beer can
From one beer can to a Ketel one helluva a player.
Congrats to Marte. Time to relax and enjoy yourself, take your foot off the gas. Have an extra cheeseburger and shot of Ketel one with every dinner.
Sincerely every other NL West fanbase.
That’s a shame he can’t be talked about on the baseball trades website anymore
Ketel still feels like a “new” player to me, hard to believe he’s hitting veteran status
