Yankees diehard, 73, notches impressive 50 straight years of Opening Day attendance: Ive dreamed of this with all three generations

Their family tradition is a total home run.A die-hard Yankees fan celebrated attending 50 consecutive years of Opening Day games Thursday — including 29 in a row with his daughters and the first ever with his young grandson, he told The Post.“It’s a very emotional day for me — I’ve dreamed of this with all three generations,” said Barry Phillips, 73, of Westtown, NY.“My girls grew up and went away to college, but every year they’ve come back for Opening Day,” said Phillips, who attended his first Major League Baseball kickoff game in 1975. “They were here in the snow and the rain.They wanted to keep the tradition alive.”Phillips’ daughters, Brett Gleis, 48, and Dana Fontanel, 43, first started coming to the House that Ruth Built with him as teenagers in 1995 —  back when superstar Derek Jeter was a no-name rookie.“That year, we see this skinny rookie, Derek Jeter, and the girls say, ‘Dad, he’s got a cute tush!’” Phillips recalled.The family had field-level seats, so when the girls yelled, “Derek, Derek!” the budding Hall of Famer ran up to say “hi,” Phillips said.

“After that, he would put his hand to his mouth and blow a kiss to them.”“So the girls started coming and they liked it,” he said.“As they say, the rest is history.”Thursday’s game against the Brewers also marked the first year Phillips’ 8-year-old grandson, Eric Fontanez, joined the fun.Meanwhile, Gleis — who dresses up in goofy costumes to celebrate Opening Day each year — donned a cheeseburger get-up for no particular reason, while the rest of the family wore Yankees hats.“We’re having a great time,” Phillips told The Post as the game got started.

“We’ve made a pact that we’re going to keep this tradition going.”The Bombers went on to win, 4-2....
