In a year in which injuries have crippled the Yankees at several positions, shortstop has taken the biggest hit.

Derek Jeter hasn’t played a game yet because of two foot fractures. Eduardo Nunez played 27 games, went on the disabled list May 6 and hasn’t been seen since due to a strained left oblique. Reid Brignac’s bat was so ill he was sent packing.

Now, Jayson Nix, who has started 40 games at short and 24 at third base, is nursing a right hamstring injury serious enough to keep him out of last night’s 7-3 win over the Twins at Target Field.

“I tweaked it after the double, it’s just something there and I want to keep it under control,’’ said Nix, who doubled in the ninth inning Monday night and remained in the game for the final three outs.

Nix said the discussion he had with the medical staff centered solely on last night. However, Nix’s absence meant Joe Girardi, who is carrying 13 pitchers, had only Vernon Wells and Austin Romine as extra players. Neither is an infielder. Alberto Gonzalez started at short and David Adams at third.

“His hamstring is a little tight, day by day,’’ Girardi said of Nix, a utility infielder pressed into far more action than he or the club could have imagined at the start of the season. “It’s not what you want. It tests your depth. It’s something you have to deal with. Right now there are no tests planned.’’

Girardi noticed Nix manipulating the leg awkwardly in the dugout after doubling and scoring Monday night.
