Predicting 3 Mets who won't be on the roster before the August 1 trade deadline

3) Why the NY Mets roster won’t have David Peterson on it before August 1

David Peterson has stuck around on the Mets roster in a new capacity. The arrival of Jose Quintana from a season’s long IL stint didn’t result in a demotion for Peterson. Instead, the Mets have been using him out of the bullpen. It might be where he ultimately lands, but with the trade deadline only a little over a week away, we might see him temporarily sent down to the minors in preparation for moving back to the rotation.

The rotation spot Peterson will eventually take is the one belonging to Carlos Carrasco. The impending free agent starter needs to get dealt before the August 1 trade deadline. Once gone, the Mets will turn to Peterson for rotation help.

Peterson was so bad as a starter for the Mets earlier this year that he already experienced a demotion. This incoming trip to Syracuse is more about roster management. Calling up a “true reliever” for about 10 days is something for the team to consider before flipping the switch and riding out the rest of the year to figure out exactly what Peterson can or cannot offer them.

Alongside Tylor Megill, Peterson is one of those fringe major league starters who at times looks impressive. On other days, an eventual slot in the bullpen seems more appropriate. Peterson will be sticking around with the organization through the end of this year but should get familiar with traveling to Syracuse when the time comes.

The biggest roster changes of all for the Mets won’t take place until the dust settles following the trade deadline. They could get a head start on things with a few late July trades and pre-planning for the days to come after.
