A love story rooted in loyalty and long-distance devotion

The journey to parenthood is just the latest step in Pete and Haley’s love story, which began long before Alonso became a Major League star. The two first met in 2015 during a summer baseball league in Cape Cod. At the time, Pete was playing summer ball and studying at the University of Florida, while Haley was a student at Michigan State University. Despite the long-distance nature of their relationship, the couple found a way to make it work—a testament to the strength and sincerity of their bond.

In a 2020 interview with ESPN, Alonso opened up about their early days. “I couldn’t stop thinking about her,” he said. “To me, she was the one.” Their connection grew over the years, even as Pete pursued a demanding career in professional baseball. Haley, for her part, supported his dreams while also building her own life and identity outside the game.

The couple got engaged in November 2018 and tied the knot three years later in a beautiful ceremony in Tampa, Florida, in 2021. Their wedding, celebrated by close friends, family, and teammates, was described by Pete as “the best day of my life.” On Instagram, he gushed about his new bride, saying, “I married the woman of my dreams in front of God, our family, and friends. I feel so lucky and proud to be your husband, @haleyralonso.”

From long-distance college lovebirds to married life as a high-profile couple, Pete and Haley have weathered it all together. Their relationship has remained grounded, even as Pete’s star has risen in the national spotlight.
