When the Yankees didn’t call Russell Martin to see what he was looking for to remain in The Bronx, the smart money was on a Francisco Cervelli-Chris Stewart spring training competition for the frontline catcher. With 13 exhibition games remaining in Florida, manager Joe Girardi isn’t even sure there will be a No. 1 catcher. “I am not married to anything,’’ Girardi said Thursday. “I kind of let it sort its way out.’’ Girardi has multiple ways he can use Cervelli and Stewart. Nevertheless, it likely won’t be the traditional deal in which one catcher starts 120 games. Or a strict platoon since they are right-handed hitters. One option is a 60-40 split. Another is pairing catchers with certain starters like Girardi did last year with ace CC Sabathia and Stewart. Or he could split the 162-game schedule evenly. “I have seen teams evenly split it,’’ said Girardi, who was a starter, platooned and a backup catcher in his playing career. “It can work out pretty well, actually,’’ Girardi said of giving each catcher 81 starts. “It keeps them fresh and they know when they are playing.”
