Nicolino was optioned to Triple-A New Orleans on Monday, Andre Fernandez of the Miami Herald reports.
Nicolino put together his first quality start since May on Sunday, allowing three earned runs on eight his across six innings in a loss to the Padres. Even so, he'll be sent down to New Orleans, while the team brings up right-hander Austin Brice to take his place on the roster. Expect Nicolino to return in some capacity next month after rosters expand.
