You’ve seen the "Polar Bear" crush 400-foot moonshots at Citi Field for years, and now he's taking that same legendary power to the Baltimore Orioles after that massive $155 million deal. But away from the dirt and the Gatorade showers, there’s a question that pops up in every sports bar and Twitter thread: Is Pete Alonso married? Yeah, he is.
Honestly, it’s not just a "yes" or "no" thing. Pete’s relationship with his wife, Haley Alonso (formerly Haley Walsh), is basically the secret sauce to his career. If you’ve followed his trajectory from a second-round draft pick to a five-time All-Star, you know he doesn't do anything halfway. That includes his marriage.
The Cape Cod Spark: How Pete and Haley Met
Most people think pro athletes meet their spouses at fancy red-carpet events or through some high-end dating app for the elite.
Not Pete.
The story actually starts back in 2015. Pete was playing summer ball for the Bourne Braves in the Cape Cod League. If you aren't a baseball nerd, the Cape is where the best college players go to prove they can handle wood bats. It’s gritty, it’s sweaty, and it’s where Pete met Haley.
At the time, Pete was a standout at the University of Florida. Haley was a student at Michigan State. They were kids, basically. But Pete knew. He told ESPN years later that he "just couldn't get enough of her." It was that old-school, "she’s the one" kind of vibe from day one.

Long Distance and Handwritten Letters
You’ve gotta respect the hustle they put into those early years. Maintaining a relationship between Gainesville and East Lansing isn't exactly a walk in the park.
Haley has shared some pretty sweet details on Instagram about how they made it work. We’re talking actual, physical handwritten letters. Pete would send them every single day while they were apart so she’d have something to look forward to in the mail. It sounds like something straight out of The Notebook, but for Pete, it was just how he stayed grounded while his career was taking off.
The Big Day: When Did Pete Alonso Get Married?
After getting engaged in late 2018—right before Pete's historic rookie season where he broke the MLB rookie home run record—they took their time planning the wedding.
Pete Alonso and Haley Walsh officially got married on November 12, 2021.
They chose Tampa, Florida, for the ceremony, specifically the Sacred Heart Catholic Church. It was a beautiful, meaningful spot that reflected their roots. Pete called it "hands down the best day of my life," which is saying a lot for a guy who has won two Home Run Derbies and a Rookie of the Year award.

The reception was a total vibe. They leaned into their heritage with:
- Tapas and paella to honor Pete's Spanish ancestry (his grandfather fled Spain during the Civil War).
- An Irish band to celebrate Haley’s background.
- A cigar rolling station on the balcony, because, well, it’s Tampa.
Life as a Growing Family: Enter Baby Hayden
For a while, it was just Pete, Haley, and their French bulldog, Brody (originally named Brady, but changed because Haley is from Boston and apparently knew way too many dogs named after TB12).
But 2025 changed everything for them.
In April 2025, the couple announced they were expecting. Fans watched Haley’s baby bump grow throughout the season, even as she joked about the struggle of wearing heels in the Atlanta summer heat during the All-Star break.
On September 21, 2025, Pete and Haley welcomed their first child, a son named Hayden. The timing was wild. Pete was in the middle of a heated pennant race with the Mets, but he made it clear that becoming a father was the ultimate "clutch" moment. Seeing the photos of baby Hayden overlooking the Manhattan skyline before the family's big move to Baltimore was a real "end of an era" moment for New York fans.

Why This Matters for the Move to Baltimore
As of early 2026, the Alonsos are settling into a new chapter. Leaving the Mets wasn't easy. Haley wrote a super emotional goodbye on Instagram, admitting she burst into tears looking at old photos of Pete in his dirt-stained Mets uniform.
But here’s the thing: Pete isn't just a solo act. When the Orioles signed him to that 5-year, $155 million contract, they weren't just getting a first baseman. They were getting a family man who is deeply supported by a wife who has been there since he was a college kid with a dream.
Haley has always been his "rock." Whether it was helping him recover after that terrifying car accident in 2022 where his truck flipped three times, or co-founding the Alonso Foundation to support youth baseball and animal welfare, she is a massive part of his professional identity.
What to Expect Next
If you’re an Orioles fan, or just a Pete Alonso devotee, keep an eye on how this family dynamic shifts in the 2026 season. Pete is 31 now. He’s a veteran. He’s a dad.
Expect to see a lot more of Haley and little Hayden in the stands at Camden Yards. Pete has always played better when he's happy, and right now, his home life seems as solid as one of his line drives.
Actionable Insight for Fans: If you want to keep up with the Alonsos' transition to Baltimore and their charity work, follow the Alonso Foundation on social media. They do a ton of work for veterans and shelter dogs, often hosting events that give fans a more personal look at Pete and Haley’s life than you’ll ever get from a box score.
