Adam Conley still figures to be the favorite.
But Jose Urena and Justin Nicolino are making their cases.
And Marlins manager Don Mattingly said the decision on who will man the final slot in the starting pitching rotation likely won’t be made until the final days of spring training.
“You really just look at both guys [Conley and Urena] and [Nicolino] and look at how do you put these guys in the best position and put us in the best position?” Mattingly said.
The Marlins revealed four of their starters Friday, with Edinson Volquez leading off on Opening Day, and Dan Straily, Tom Koehler and Wei-Yin Chen following him in that order.
