Matz, sidelined with a strained shoulder, threw off flat ground Friday and will try to throw off a mound on Saturday, though there is no timetable for his return, SNY.TV reports.
It sounds as if the Mets will be cautious with Matz rather than rushing him back, aided by the solid pitching of Seth Lugo and Robert Gsellman. If Matz has no issues Saturday, he could progress to a simulated game and then possible return to the rotation.
