Father’s Day arrived early for former Yankees relief pitcher Ron Davis. His son Ike, a former Met, is joining the Yankees, and the two shared a father-son moment by phone Sunday after Davis agreed to terms on a major-league contract. The first baseman had been in Triple-A with the Rangers, who released him so he could join the Yankees.

“I’m so happy for him,’’ Davis, 60, said Monday from Scottsdale, Arizona, shortly before the Yankees officially announced the signing. “His first thing was, ‘Dad, I hope they have your number [39] available.’ He was so excited to play at the place I played and maybe use my number. Someone texted me and said another young man [reliever Kirby Yates] already has that number.’’ Davis will wear No. 24 with the Yankees.

Ron Davis, who had an 11-year major-league career, enjoyed his best years with the Yankees setting up Rich “Goose” Gossage. He made the All-Star team in 1981, the year he struck out eight in a row — a Yankees record for a relief pitcher.

He’s hoping his son’s career will be rejuvenated in New York, this time in the Bronx. No words of wisdom are needed.

“I don’t think there’s anything to tell him,’’ Davis said. “He’s played four years in New York. I know it was for the Mets, but both teams are equal for the press and playing for the people. A healthy Isaac is a good thing for the Yankees. Listening to him, I would say he thinks he’s ready to play every day.’’

Ike Davis had a .268/.350/.437 slash line with four home runs and 25 RBIs in 142 at-bats for Triple-A Round Rock.

Ron Davis — who said he will be in Denver on Tuesday night for the Yankees-Rockies game — knows nothing is guaranteed for his son. Ike might occupy the position (possibly sharing time with Rob Refsnyder) only until Mark Teixeira returns from the disabled list.

The rightfield porch at the Stadium should be inviting to the lefthanded-hitting Davis if he can regain his home run swing.

“It’s like any kid if he’s 22 or 18 or 33,’’ Ron Davis said. “There’s always somebody that wants your job, and if you get lucky enough to get an opportunity, you have to make it worthwhile. You always have to prove yourself. It’s like OK, I have a month to do this, it may be a day, an at-bat, you gotta show you can do it. If you do, you stay. If you don’t, you gotta go work on it some more. The Yankees’ guys are getting older, not that they’re old, but you know, they’ve had a history of injuries.’’

Davis, 29, was chosen 18th overall in the first round of the 2008 MLB amateur draft by the Mets and had his best year for them in 2012 when he hit 32 home runs and drove in 90 runs. Injuries and inconsistency prompted the Mets to go with Lucas Duda, and in April 2014, Davis was traded to the Pirates.

“Lucas is one of Ike’s best friends,’’ Davis said. “The Mets made a decision. Honestly, I think they flipped a coin. With the Mets, it seemed like everything [Ike] did was under the microscope. He has to hit this, or he has to hit behind David Wright to protect David Wright, which is all good, but I think he’s going to go to the Yankees and he could bat anywhere from sixth to ninth, who knows.

“Whatever production they get out of him is going to be great. They know he’s going to help the middle infielders as far as picking it over there and defensively he’s going to make the infield a lot better. If he can come back to his form, it would be a perfect match for the Yankees.’’

Davis hopes his son has staying power, saying, “I’d like to go back one day to Old-Timers’ Day and he is the starting first baseman.’’
