Yankees’ Paul Goldschmidt exits after 3 innings with sore back

DUNEDIN, Fla. — Paul Goldschmidt said he has “zero” doubt he’ll be in the Yankees’ lineup for Opening Day.

But, as former Yankees manager Joe Girardi always used to say, “Backs are tricky.”

And Goldschmidt’s has been acting up in recent days and it brought his Monday afternoon to an early end in the Yankees’ 6-5 loss to the Blue Jays at TD Ballpark, the continuation of what has been Camp Cataclysm for the team as far as injuries go.

“My back’s been a little sore, so we kind of made the decision to stop there after three innings,” Goldschmidt said of himself and manager Aaron Boone. “I could have played the whole game, but in spring training you just try to be smart. No need to kind of push through something and possibly make it a little bit more sore.”

The 37-year-old Goldschmidt, who signed a one-year, $12.5 million free-agent deal over the winter to be the Yankees’ primary first baseman, has been among the club’s offensive standouts this spring, hitting .323 with three homers and a 1.259 OPS in 12 games. The four-time Gold Glove Award winner has been his usual solid self in the field.

Goldschmidt, who as of now will not be sent for tests, estimated he’s been dealing with the soreness the last “four or five days.”

“[It’s] not really getting worse, but obviously is still something that was there and just thinking, ‘Is this really the time to push it?’ ” Goldschmidt said. “And I think the answer is no.”

He emphatically said he has “zero” concern when it comes to the season opener March 27.

“It should be fine,” Goldschmidt said.

After Tuesday’s game, Boone said Goldschmidt already had a scheduled day off Wednesday and he “expects” to play the first baseman at home in a split-squad game against Atlanta.

“It was more, those first two innings were so long and he’s standing [a lot],” Boone said of the first two innings that took nearly an hour to play. “He [said] he could keep going but I’m like, ‘No, let’s get out of there.’ Nothing I don’t think is anything too big.”
