Andy Pettitte was on hand to see his son sign his Yankees contract — as was another soon-to-be member of the family.

As Luke Pettitte, son of longtime Yankee pitcher and current special adviser Andy, arrived to sign with New York after being selected in the eighth round of the 2026 MLB Draft, his parents and fiancee Brooklyn joined him for the special moment on Wednesday.

The family posed for a photo in front of a TV screen, reading “Welcome to New York Luke Pettitte.”

Brooklyn stood next to the younger Pettitte while surrounded by parents Andy and Laura.

Luke and Brooklyn got engaged in May, in which the young ballplayer got down on one knee seemingly on a seaside cliff. He laid out a small blanket surround by beautiful hydrangeas.

They announced the big moment through a joint Instagram post that included a photo of Luke kissing Brooklyn on the cheek as she showed off her ring.

“WE ARE GETTING MARRIED!!!” the post reads. “The Lord has been so faithful in our relationship these past three years! I am so beyond blessed to get to love someone who reflects Jesus so evidently for a lifetime! THE FUTURE PETTITTE’S!!! 🤍🤍”

The couple has been together since high school in 2023 and both went on to Dallas Baptist University.

They recently had an engagement photo shoot where the DBU cheerleader wore a simple low-back white dress and Luke sported a white collared shirt with jeans.

It will be a big year for the pair with Luke embarking on a new career adventure and with the upcoming wedding date, Oct. 4, 2026, as Brooklyn announced on Instagram in June.

Luke, 21, did not pitch this season at Dallas Baptist due to undergoing Tommy John surgery last year. Instead, he served as the DH and went on to hit 16 home runs in 42 games.

The two-way player has gotten his family fired up over the signing.

His brother Josh shared a video of one of Pettitte’s college home runs on his Instagram story and wrote “This is gonna be so sick in Pinstripes.” Luke reposted it on Wednesday.

Andy Pettitte has four kids — Josh, Jared, Lexy and Luke. He coached all of his sons in high school and they all went on to play at Dallas Baptist University.

The former three-time All-Star won five World Series titles with the Yankees before he rejoined the franchise in 2023.
