Breaking: Diamondbacks all-star second baseman Ketel Marte has a new extension, sources tell ESPN. Already locked up through 2028, he’s in agreement on a 6-year, $116 million contract which starts this season. It includes a player option in 2031 for $11.5 million.

Marte entered Wednesday hitting .273 in the early stages of this season. The two-time All-Star slashed .292/.372/.560 in 136 games last season for the Diamondbacks.

The 31-year-old infielder has only gotten better with age as he has combined to produce over 10 WAR in his last two full big-league seasons.
An extension of this magnitude indicates the Diamondbacks firmly believe they have built a contender that can challenge the Dodgers for the National League West. Arizona missed the playoffs in 2024 but came up just short in the World Series in 2023 against the Texas Rangers.
Marte will be a valuable piece to the puzzle for years to come for the Diamondbacks' core alongside Corbin Carroll, Josh Naylor, and Corbin Burnes. He becomes the fourth player to sign an extension in Arizona.
Geraldo Perdomo signed a four-year extension in February while Justin Martinez and Brandon Pfaadt signed five-year extensions within the last 60 days. All four players are expected to have big roles for the Diamondbacks.
