When Robinson Cano left The Bronx for Seattle, the Yankees turned to Brian Roberts at second base in 2014. When Roberts needed to be replaced, Stephen Drew was acquired from the Red Sox.

As of Thursday, the plan for 2015 was Martin Prado at second.

That plan was scratched Friday when the well-respected and productive Prado was dealt to the Marlins.

So, what becomes of second?

Six days before Christmas, general manager Brian Cashman explained that neophytes Jose Pirela and Rob Refsnyder will compete for the job if another addition isn’t made.

“It’s a competition right now that exists on the current roster. I will evaluate opportunities that present themselves but clearly if spring training started today that’s the competition,’’ Cashman said after acquiring Nathan Eovaldi, Garrett Jones and Domingo German from the Marlins for David Phelps and Prado.

While Roberts provided an experienced head to take over for Cano, Pirela’s and Refsnyder’s combined big league experience consists of seven games; all belonging to the right-handed hitting Pirela.

The possibility is strong that Refsnyder, 23, a converted right-handed hitting outfielder who hasn’t impressed defensively at second in the minor leagues, and Pirela could share the position.

Refsnyder, a fifth-round pick in 2012 from the University of Arizona, hit .318 with an OPS of .884 this past season for Double-A Trenton and Triple-A Scranton/Wilkes-Barre, and it’s his bat that has put him on the map.

Pirela, 25, batted .305 with a .792 OPS in 130 games at Triple-A. In seven big league games, Pirela batted .333 (8-for-24) with a .902 OPS. He also showed a live body and could be a bench player if Refsnyder plays well enough to be a full-time player.
