As the World Series moves to the Big Apple following the Los Angeles Dodgers’ Game 1 and 2 victories over the New York Yankees in L.A., there are plenty of flyover connections between Major League Baseball’s West Coast and East Coast titans.

Fairview High School and its baseball and softball coach, David Castillo, among them.

The 43-year-old, who just finished up coaching the Knights in softball, has a close relationship with Yankees catcher Jose Trevino. David was one of Trevino’s baseball mentors. And his dad, Steve — a legendary high school baseball coach in Texas — is someone the 31-year-old MLB veteran still refers to as his “second Dad.”

Over the weekend, Trevino flew the Castillo family out to New York and gave them tickets to Game 4 on Tuesday and Game 5 on Wednesday. David said he set them up in a nice hotel and got them a personal driver.

“He grew up watching me play. Our high school, we used to have like 10,000 people at our high school games. And that was just a normal game,” recalled David, the star catcher from south Texas who everyone was talking about before Trevino.

The Knights coach played for his father at Moody High School in Corpus Christi, where Steve built a baseball empire and became a local legend. David was drafted by the Oakland Athletics in 2003.

Years later, Trevino helped Steve win his first state title as a coach, leading back-to-back title wins in 2010 and ’11.But the relationship between the Castillo and Trevino families was more than baseball. Even if it often did center around it.

Trevino would spend some of his high school days at the Castillo home, just watching the game. The big leagues were his dream, and Steve and David were there to help push him, sometimes with tough love, towards it.

The three of them would then wake up before the sun to start training.

“I’d wake up, Jose is ready to rock, and then we run from my house to the school, which is a little bit over three miles away. I’m wearing a weighted vest,” Castillo recalled. “We get to John Paul, and we start to work. Weight room for an hour. Then after that, let’s see if we can hit, let’s see if we can play ball.”

He’d tell Trevino: “If you’re a catcher, you have to learn to play tired. Your whole life is that.”

Trevino was a junior by the time he led John Paul II to its first title in 2010.

A state championship had been the one thing missing for Steve, who for all his coaching accolades since starting as Moody’s baseball coach in 1979 had previously come up just short of winning it all in the three decades before.

Among his three runner-up finishes came in 2000. David, who’d long promised his dad to win a state title for him, was his star player then, and had a chance to do just that in the final inning of that season’s championship game.

Down 3-2 with the tying and winning runs in scoring position, “I hit a missile down the first-base line and the guy playing first, Vincent Sinisi, who played in the big leagues, made a full-extension catch,” David sighed. “I failed the goal I gave to my father.”

Ten years later, though, he told his dad, ‘I’m going to keep my promise.’” Trevino, who left John Paul II with multiple state records, helped make sure of it.

After high school, Trevino followed David’s footsteps to Oral Roberts University. Both are in the school’s athletics hall of fame.

While there, though, Trevino almost gave up the game following his dad’s death in 2013.

His dad Joe, or Bugé as he was called, loved baseball. He was a volunteer coach, umpired and was a Yankees fan. Throughout his big-league career, Trevino talked publicly about how his father did whatever he could to help give his son a chance to play in the MLB.

Part of that was asking for help from the Castillos, who never did let him walk away.

“My dad would call me and say, ‘He’s trying to quit. He can’t. He can’t,’” David said. “And now, like the other day, Jose is texting me. He’s like, ‘This is unbelievable.’ And it is. It’s storybook.”

Drafted by the Texas Rangers in 2014, Trevino made his big-league debut in 2018. His first MLB hit came against Colorado Rockies pitcher Kyle Freeland. A day later, on Father’s Day, he walked off the Rockies with a two-run single.

“He means everything to me,” Trevino said about Steve after the game. “He’s like a second Dad.”

The ball from Trevino’s first hit in the majors is still locked away in Steve’s house. David said it’s his job to put the ball into his father’s casket one day, so Steve can then pass it on to Bugé.

This week, Trevino will try and help secure another overdue championship. The Yankees won their MLB-leading 27th and last World Series title in 2009. They trailed 2-0 in the best-of-seven series coming into Monday’s Game 3.

“Just to be part of this moment,” David said, “it’s awesome.”
