Syndergaard (elbow) will continue his rehab assignment with Triple-A Syracuse this week, Justin Toscano of The Bergen Record reports.
The 28-year-old made his first rehab outing with Low-A St. Lucie on Wednesday and gave up one hit and no walks while recording five strikeouts over four scoreless innings. Syndergaard is about 14 months removed from last year's Tommy John surgery, and the Mets expect him to join the team sometime in mid-June, so he'll likely log a few more rehab starts in the minors.
