From College Sweethearts to MLB Power Couple
The love story of Pete Alonso and Haley Nist began long before the "Polar Bear" became a household name in Major League Baseball. The couple met around 2015 while attending Michigan State University, where Haley studied journalism and Pete was a rising star in collegiate baseball. When Pete transferred to the University of Florida to elevate his draft stock, the couple successfully maintained a long-distance relationship.
Following her graduation, Haley joined Pete as he rose through the minor league ranks. Pete proposed in the fall of 2020, and the couple officially married on November 12, 2021, in a stunning ceremony in Boston, Massachusetts. Over the years, Haley has been a constant fixture in the stands, famously cheering Pete on through multiple All-Star games, high-stakes playoff runs, and historic Home Run Derbies.

Beyond the baseball diamond, Haley Alonso plays a critical, hands-on role as the co-founder of The Alonso Foundation. Established in 2020, the non-profit organization is dedicated to supporting advocacy groups, raising awareness, and funding crucial initiatives for those in need. Haley’s background in digital media and communications has allowed her to effectively spearhead the foundation's public relations and community outreach.
The foundation actively directs resources to three primary pillars:
- Animal Welfare: Promoting shelter adoption, supporting rescue organizations, and funding emergency care for animals in crisis.
- Youth Initiatives: Providing resources, gear, and safe spaces for youth sports leagues in underserved communities.
- Veteran Support: Partnering with organizations that assist veterans transitioning back to civilian life and supporting post-traumatic stress recovery programs.
Through her active lifestyle blog and social media platforms, Haley consistently promotes these causes, turning her personal platform into a vehicle for social good.
