The upcoming MLB trade deadline promises to be a complex affair, with a majority of teams contending for playoff spots. The Arizona Diamondbacks hold a pivotal role, with several key players potentially on the trade block, including Eugenio Suárez and pitchers Merrill Kelly and Zac Gallen. Despite their recent struggles, the Diamondbacks' ownership may hesitate to dismantle a team that has worked hard to chase a playoff spot. The Miami Marlins' sweep over Arizona worsened their playoff odds, while injuries, particularly to Corbin Burnes, have left the pitching rotation in shambles. With July 31 approaching, all eyes will be on teams like the Detroit Tigers, Seattle Mariners, and St. Louis Cardinals looking to fortify their lineups.
