DeGrom (shoulder) is set to throw a Sunday bullpen session, and could return to the mound for the Mets next weekend against the Dodgers, Adam Rubin of ESPN New York reports. DeGrom threw off flat ground Saturday, and will continue to progress quickly with his rehab program. The Mets head to Los Angeles Friday to begin a three-game series with the Dodgers, and this seems to be DeGrom's tentative target return date.
