SEATTLE — The first domino fell Thursday when the Mets traded Lucas Duda to the Rays and created an opening at first base. Before the July 31 trade deadline, it’s possible the Mets could have another opening if the team trades Asdrubal Cabrera.

As there is uncertainty about who will compose the infield over the final two months, the Mets are now looking to be more versatile with how they use their infielders.  

One particular player who could be affected is Neil Walker, who the team is now considering using at first base and third base after being activated off the disabled list Friday. Walker has not started at any defensive position other than second base since 2010, but played one game at third base during his rehab assignment. 

Walker went 1-for-4 with the game-winning RBI in Friday’s 7-5 win over Seattle. 

“We don’t know what is going to take place here in the next two or three weeks,” Mets manager Terry Collins said at Safeco Field. “(Walker) has got to be able to give us some versatility. He went down and played third (during his rehab assignment). We know he can play first. We know he can play second. This just gives us another option.”

The Mets are expected to make at least one more move in the next few days, and it’s possible Addison Reed, Jay Bruce and Asdrubal Cabrera could be traded. Reed is the most likely to go since contending teams are always in need of quality relievers.

The markets for Cabrera and Bruce have not been nearly as robust, but, in Cabrera’s case, it would make sense for the Mets to move him to create an easy opening for Amed Rosario. While the team won’t let Cabrera stand in the way of calling up their stud prospect, trading the veteran would make it…
