In the world of Major League Baseball, talent often runs in the family. For Arizona Diamondbacks outfielder Alek Thomas, that couldn’t be more true. Born on April 28, 2000, in Chicago, Illinois (though some sources note Tucson ties through heritage), Alek has carved out an impressive career as a left-handed hitting center fielder. But behind his journey—from high school standout to MLB regular—stand supportive parents who shaped his love for the game. Let’s dive into Alek Thomas’s parents, their influence, and how family has fueled his success.

Who Are Alek Thomas’s Parents?
Alek Thomas’s father, Allen Thomas, is a longtime baseball figure. Allen spent nearly three decades with the Chicago White Sox, serving as Director of Strength and Conditioning from the mid-1990s until around 2021-2022. He was part of the White Sox’s 2005 World Series championship team, even wearing his 2005 ring proudly during Alek’s big moments, like the Diamondbacks’ 2023 postseason run.
Alek’s mother, Marella Thomas, has been a quiet but constant force. She comes from Mexican heritage, which has allowed Alek to represent Team Mexico in events like the World Baseball Classic (WBC). The family blend of backgrounds—Allen’s deep MLB coaching ties and Marella’s cultural roots—has given Alek a unique perspective on the game.
Alek has siblings too: a sister named Alana and a brother named Josh. The Thomas household was always baseball-centric, with family photos showing everyone together at games and events.
How Allen Thomas Influenced Alek’s Baseball Journey
Growing up with a dad in pro baseball gave Alek an inside track. Allen wasn’t just a coach—he was a former minor leaguer (drafted by the White Sox in 1996, reaching Class-A) who transitioned into strength training. This meant Alek spent time in clubhouses early on.
- Early exposure: Alek hung around White Sox facilities, learning routines and discipline.
- Heartwarming moments: In spring training years ago, Alek hit a three-run homer and looked to the opposing dugout for his dad’s reaction—Allen stayed professional but couldn’t hide his pride.
- World Series bonds: Allen shared stories of the 2005 White Sox title with young Alek (just 5 at the time). Fast-forward, and Alek helped the Diamondbacks reach the 2023 World Series—making it a family affair across two teams.
- Recent highlights: In the 2026 WBC setup, Allen served in coaching roles for international teams (like Mexico or Brazil in exhibitions), adding fun crossovers with his son.
Allen’s emphasis on conditioning helped Alek become a well-rounded athlete—he was even a two-sport star (baseball and football) at Mount Carmel High School in Chicago before the Diamondbacks drafted him in the 2nd round (63rd overall) in 2018.
Marella Thomas: The Cultural and Emotional Anchor
While Allen brought the baseball know-how, Marella provided the heart and heritage. Alek has spoken about connecting with his Mexican roots through her side of the family, including time spent in places like Agua Prieta, Sonora.
This heritage shone in the WBC, where Alek played for Team Mexico—honoring his mom’s background while chasing international glory. Marella was there for big milestones too, like Alek’s MLB debut on Mother’s Day in 2022, where he got his first big-league hit.
The family dynamic shows balance: competitive drive from dad, emotional support and cultural pride from mom.
