The Diamondbacks will keep Ketel Marte, rejecting trade offers ahead of the 2026 season.

The Arizona Diamondbacks will not trade second baseman Ketel Marte before the 2026 season, according to multiple reports citing Ken Rosenthal of The Athletic and team general manager Mike Hazen. Despite interest from teams including the Red Sox, Pirates, Giants, and Mariners, Arizona found no trade offers compelling enough to move Marte, who is nearing 10 years of service time and holds 10-5 trade protection rights. Marte, under a team-friendly contract, is expected to remain a core player as the Diamondbacks focus on addressing needs in pitching, the outfield, and first base while operating under a constrained payroll. The decision shifts attention to free agents like Alex Bregman and Bo Bichette.
