Iglesias is out of the lineup for Thursday's game against the Nationals due to an illness, Steve Gelbs of SportsNet New York reports.
Though he had been expected to start Thursday against southpaw MacKenzie Gore, the right-handed-hitting Iglesias apparently felt ill during Wednesday's 6-2 win and required an IV after cramping up following the game. Iglesias is apparently still feeling under the weather Thursday, so the Mets will let him rest in the series finale while Jeff McNeil steps in at second base.
