The MLB trade deadline is on July 31 and trade speculation and rumors are running rampant. The Arizona Diamondbacks are in the middle of the speculation. In fact, one MLB insider says the team could be the "epicenter of the trade deadline.

The stunning trade that sent Rafael Devers to the San Francisco Giants not only left Boston Red Sox fans looking for an explanation, but it kicked Major League Baseball’s trade season into high gear.

The Cubs should look to add at the MLB trade deadline, and the Diamondbacks have the perfect fits if they are sellers.

The Diamondbacks made a move to shore up their organizational pitching depth, signing right-hander Anthony DeSclafani to a major league contract and fitting him on the roster by optioning right-hander Bryce Jarvis to Triple-A Reno.

On Thursday, the Arizona Diamondbacks announced they were making a roster move, designating right-hander Scott McGough for assignment while reinstating Andrew Saalfrank and optioning him to the Arizona Complex League.

The Arizona Diamondbacks are getting calls about possible trades, ahead of the MLB trade deadline. Arizona is hesitant to take the calls.

Diamondbacks lefty Andrew Saalfrank was reinstated on June 5 as his one-year ban for gambling on baseball ended.

The San Francisco Giants' stunning deal to acquire Rafael Devers from the Red Sox could mean another hurdle for the Diamondbacks.

Watch out for the Yankees to be on the Diamondbacks slugger should Arizona put him on the trade block as the deadline looms.
