On the afternoon of July 3, a few employees of The Bristal Assisted Living facility in Lake Grove were spotted wearing New York Mets shirts. They had a particular reason — they were preparing to celebrate the 100th birthday of one of their residents, who happens to be a big New York Mets fan.

As they prepared, Crispin Bottari, the guest of honor, sat in the game room wearing a Mets T-shirt and a decades-old hat that featured the team’s logo and the Mr. Met mascot. The room is where he and his wife regularly work on puzzles that they later laminate for keepsakes.

The party that night wasn’t the first one for the centenarian. Bottari said a few days earlier his family threw one for him at the Blueblinds Mansion in Smithtown, where nearly 150 guests were in attendance.

“It felt like my heart was bursting when I saw all those people,” he said. “I had tears.”

Born July 3, 1919, in Williamsburg, Brooklyn, he grew up a fan of the Brooklyn Dodgers until they moved to Los Angeles in 1957. He said when he first met his wife, they would go to Ebbets Field in Brooklyn every Sunday and watch the team play.

A few years after the Dodgers departure, he discovered the Mets, initially watching them play at the Polo Grounds in Upper Manhattan before Shea Stadium was built in Queens. He remembers taking his daughter to a 1969 World Series game, the year the Mets won.

“They were misfits at the time, but they played, and they won a pennant, and in ’69 they won the World Series,” Bottari said.

A year ago, he had the chance to watch the team play at Citi Field, where he attended a ceremony honoring World War II veterans. Out of a few people that were invited, he said he was the only one able to attend, and the ballplayers presented him with a flag and a baseball.

Bottari said he doesn’t have a favorite player now, but he lists Tom Seaver among his favorites from the 1969 Miracle Mets.

“Talk about gung-ho,” he said. “They did it the way it should be done.”

While Bottari and his family love baseball, there is another love in their lives — music.

“Music in my family precedes everything, because everyone in my family somehow, someway is musically inclined,” he said, adding he owns a 70-year-old guitar that was given to him by his father that he is unable to play nowadays due to arthritis.

He remembered playing that guitar when he first met his wife, Anne. She was in a group called the Mayfair Trio with her sister and friend, and he would accompany them on guitar. The group would entertain injured soldiers in hospitals along the East Coast.

Bottari said he enjoyed seeing the big bands play in the city when he was a young man. One day he went to the Paramount Theatre in New York City to see Benny Goodman and his band, and he noticed that Frank Sinatra was also billed as playing. He said at the time he hadn’t heard of Sinatra and was surprised to see hundreds of teenage girls screaming and yelling.

During World War II, while serving in the Army with the 417th Engineer Company building airstrips in Greenland, Bottari met Sinatra, who he said would have breakfast with the soldiers every morning for the week he was in Greenland. While Bottari enjoyed having the singer around and took a picture with him, his fellow soldiers, who hadn’t heard about the entertainer, didn’t know what the big deal was and asked what his name was.

“Frank Sinatra,” he told them. “When the war is over, you’re going to hear about him,” he said.

While baseball and music have played a big part in Bottari’s life, family is the most important to him. His father, who was a tailor, immigrated to the U.S. from Italy when he was a teenager. He said his parents met through a matchmaker. At first, his mother felt hesitant about her future husband, because he didn’t speak English, but her mother encouraged her to teach him. The two would sit in the parlor and practice the language. Bottari is one of four sons born to the couple.

The centenarian said he never would have imagined celebrating his 100th birthday. While his mother lived to be 97, his father died of a cerebral hemorrhage at the age of 50, while coming out of a subway station.

“Fifty years old,” he said. “What is wrong with this picture.”

Bottari said another sorrow in his life was the death of his three younger brothers.

Despite the sorrow of losing his brothers, his own family has brought him immense joy. Sixty-nine years ago, he married his wife, Anne, who is now 94 years old.

He said he was at a dance and when the young woman he was dancing with excused herself to talk to someone else, he started talking to Anne. He asked his future wife for her phone number, and when she said she didn’t have a pen, he said, “I can solve that situation,” and lit a match and used the charcoal to write her number on the matchbook.

As for the secret to a long marriage, Bottari said it’s important to talk to each other.

“If you have a problem, resolve it,” he said.

Anne Bottari agreed and described her husband as an easygoing man. Both also said it helped that they had children who always got along and visit them often, because it keeps them going.

The Bottaris raised their five daughters in Jamaica, Queens.

“One smarter than the other,” he said. “They’re smarter than their father.”

With six females in the house, to get a chance to get into the bathroom before going to work as an accumulator of salaries for the Social Security Administration in the city, Bottari said he would wake up an hour earlier than needed.

Nearly 40 years ago, when their daughters began moving out of the house, the Bottaris relocated to Selden to be near their children, who were starting to have children of their own. The couple now has 11 grandchildren and five great-grandchildren.

Through the years in Selden, the biggest change Bottari said he has seen is the increase of the numbers of condos and stores in the area.

The couple moved into The Bristal in 2015, but Bottari said they get out often to attend family functions. He loves visiting his daughter and son-in-law, Donna and Matty Kaspak, in St. James and seeing their dog, Cooper. His son-in-law said that Bottari is always there when the family needs them, whether it’s to see his nephew playing with a band or his grandson wrestling.

“The TV goes off, and he’s in the car,” Kaspak said.

When it comes to tips for living a long life, Bottari said he’s not sure he can speak about what to eat or not eat, admitting he loves a hot dog and a beer at a baseball game.

“Each individual person has his own genes that he’s acquired from someone else in his family,” Bottari said.

On the night of his 100th birthday, in addition to family and friends, retired Mets player Frank Catalanotto was on hand at The Bristal, and Bottari received a custom-made Mets hat with his name and number 100 on it and a plate signed by Catalanotto from the facility’s employees.
