The Boston Red Sox are reportedly poking around the Arizona Diamondbacks starting pitching rotation ahead of Thursday's MLB trade deadline.

All three pitchers are seen as likely candidates to be traded before the deadline. The Diamondbacks have already started selling players approaching free agency. They flipped first baseman Josh Naylor to the Mariners and outfielder Randal Grichuk to the Royals. They will likely trade third baseman Eugenio Suárez as well.

Arizona Diamondbacks former ace Zac Gallen has not had a year that's lived up to his high standards. But that doesn't mean teams don't see trade value in him.
