The Arizona Diamondbacks have been an active team at the MLB trade deadline, and Merrill Kelly or Zac Gallen could be the next to leave.

Arizona Diamondbacks trade predictions for Eugenio Suarez, Josh Naylor, Merrill Kelly, Zac Gallen before 2025 MLB trade deadline on July 31, 2025.

Seattle dealt left-handed pitcher Brandyn Garcia and minor league right-hander Ashton Izzi to Arizona in exchange for Naylor, a 28-year-old first baseman hitting .292 with 11 home runs and 59 RBI in 93 games for the Diamondbacks this season.

NYC Council Minority Leader Joann Ariola’s nephew Joe was selected by the Arizona Diamondbacks in the Major League Baseball Draft last week — and the longtime Mets fan is already switching her allegiances.

The New York Yankees pulled themselves out of the running for Eugenio Suárez, and now Jon Heyman believes the Chicago Cubs and Seattle Mariners are the leaders.

Diamondbacks general manager Mike Hazen said on Friday that he has received calls for players with multiple years of control, including Ketel Marte.
