An up-rising MLB figure, Alek Thomas, often shares pictures with his longtime girlfriend, Kailey McCaffrey, whom fans often mistake as his wife.
McCaffrey, an Illinois native, has been in a relationship with Thomas ever since his high school days. The year 2025 marks their eight years of togetherness.
Be it to cheer up in his games or family gatherings, Kailey is always by Alek’s side. Indeed, in essence, she is already taking up the role of his wife.
Alek Thomas, the 2nd round 2018 MLB draft pick, plays for the MLB team Arizona Diamondbacks. It was after his four seasons in the minor league that he made his debut in the major league in 2022.
Aside from the MLB, he played internationally- representing the USA at the 2017 U-18 Baseball World Cup and Mexico at the 2023 World Baseball Classic.
The Tucson, Arizona-born progressed to professional baseball right out of Mount Carmel High School.
Before the Diamondbacks took him in, he was committed to Texas Christian University to play college baseball and football.
Along with his determination and talent, his parents, Allen and Marcella Thomas, played another significant role in his success.
His father is a former baseball player who worked with the White Sox for nearly three decades.
