PORT ST. LUCIE — Alex Rodriguez and Joe Torre have resumed a relationship that the ex-manager said wasn’t nearly as bad as it was portrayed when Rodriguez played for him.

“I talked to Alex last week, actually, because I was over in the Yankees’ camp,” Torre said before the Mets beat the Yankees, 6-0, at Tradition Field on Sunday. “Obviously, what Alex did was wrong. He admits that. There’s nothing left for him to do but play baseball.”

Torre, an MLB executive vice president, and Rodriguez have communicated in several forms since last fall when Rodriguez’s one-year suspension was just about up, including when A-Rod sent Torre a text after Torre’s brother, Frank, passed away in September.

Torre will throw out the ceremonial first pitch at Yankee Stadium on April 6 for the season opener against the Blue Jays.

Rodriguez played five innings at third base in a minor league game against Toronto in Tampa and went 2-for-5 with two singles as he adjusts to working with new hitting coach Jeff Pentland and assistant Alan Cockrell, who replaced Kevin Long.

“At this point, I pretty much know what I want to do in the box,” said Rodriguez, who will DH in a minor league game on Monday. “But it’s good to have a sounding board. Those guys have been around the big leagues for a combined over 50 years or more.”

Carlos Beltran, who served as a DH Sunday and went 1-for-3 with a walk, will play right field in another minor league game Monday.

“The elbow is in the past,” Beltran said of the injury that bothered him for most of 2014. “I still feel a need to gain more strength throwing-wise, but that will come with playing catch. It has improved ever since the first day I got here.”

According to manager Joe Girardi, Jacoby Ellsbury’s oblique strain is improving and the center fielder and leadoff hitter will resume baseball activities this week.

Girardi said discussions centered on who will be the fifth starter and backup catcher have been held ahead of who will be the closer.

“It’s kind of on the back burner for us,’’ said Girardi, who admitted he could mix and match Dellin Betances and Andrew Miller in the closer’s role during the regular season. “We feel good about our bullpen.’’

Masahiro Tanaka is due to start again on Wednesday, seemingly lined up to pitch on Opening Day, and the right-hander said he would “absolutely” consider it an honor to get the call against the Blue Jays for the opener.

But for now, his focus remains largely elsewhere.

“It will be a great thing if a pitcher is able to pitch on Opening Day,” Tanaka said after his 36-pitch bullpen session at Steinbrenner Field on Sunday morning. “But for me, obviously, I got hurt last season, so my main goal here is to have a healthy season throughout the year.”

The Yankees say no decision has been made, since the two leading candidates, Tanaka and CC Sabathia, are coming off injuries from a year ago.

“We haven’t decided,” pitching coach Larry Rothschild said. “We have options. There’s a bunch of possibilities. We’ll see how things go.”

Tanaka has impressed this spring, coming back from a partially torn UCL.

He hasn’t started on Opening Day since 2012 while with the Rakuten Golden Eagles in Japan.

“That was the one and only time I started for Opening Day,” Tanaka said.

The following season was impacted by Tanaka’s appearance in the WBC. And last year, Sabathia started the opener and Tanaka didn’t take the mound until the fourth game, as the Yankees tried to temper expectations.

Sabathia has taken the mound for each of the past six openers since signing with the Yankees — and is without a win in any of those outings — since Chien-Ming Wang started in 2008.

Lefty Gomez is the only other Yankee pitcher to start six straight Yankees openers.
