With Derek Jeter sidelined until after the All-star break with a fractured left ankle, Eduardo Nunez figures to be the Yankees’ shortstop for the foreseeable future. “I hope he comes back this year, I hope he comes back healthy. But I prepare myself to play every day all year long. ... It’s what I’m looking for all my life, to play all season,’’ said Nunez, who made his first error of the year in the Yankees’ 6-2 loss to the Diamondbacks Thursday night at the Stadium. “It’s not going to be the last. The errors come because we play. Turn the page. Tomorrow is a new day, keep working hard.’’ Jeter, who fractured his left ankle in last October’s ALCS, flew to Charlotte for an unscheduled visit with Dr. Robert Anderson. A CT scan showed a small crack, but it’s big enough to thrust Nunez into the starting role for the next three months. “If [manager] Joe [Girardi] tells me that’s going to be my position for awhile that’s good for me I can say that, but I feel bad for Derek and the team we lost the captain,’’ said Nunez, who went 1-for-5 last night. “We have a good relationship. I thank him for everything, how to play, how to act outside the field too. I’ll never be Derek Jeter. He’s the only one who can do what he [does]. I’ll try to do my best; give everything I have.’’ The Yankees also have Jayson Nix on the roster and Gil Velazquez — who saw time in spring training at shortsop — in the minors. But for the moment, Nunez is the primary option, and with Jeter turning 39 by the time he returns, its important he performs well. Nunez — after committing seven errors in 30 appearances in the field last season, and four in 16 appearances at shortstop for a subpar .931 fielding percentage — hadn’t committed any this season until he one-hopped a throw to first off Martin Prado’s eighth-inning grounder. Nunez also was ruled to have missed a ninth-inning tag on Cody Ross at third in what could have been an inning-ending double-play.
