The Yankees finally settled on their 26-man Opening Day roster — for Thursday’s game anyway.

After making their signing of outfielder/first baseman Franchy Cordero official, the Yankees opened the season Thursday with a roster that included 14 position players and 12 pitchers — one arm short of how they will typically operate during the season.

But manager Aaron Boone indicated the Yankees would soon add a 13th pitcher — meaning an eighth reliever — with the club having a “potential deal” for another arm.
