Zack Greinke will start Saturday or Sunday at Citi Field against the New York Mets, Manager Don Mattingly said.
Greinke, who has a scoreless streak of 43 2/3 innings, returned to Los Angeles on Thursday for the birth of his first child. He was expected to fly back Friday evening to New York.
Greinke was originally scheduled to start Friday in a game that will now be started by left-hander Ian Thomas.
Greinke could pitch Saturday and step into the place in the rotation that was vacated when Brandon Beachy was optioned to triple-A Oklahoma City.
