A trip to a Chicago White Sox game became the best day of life for 29-year-old Jacob Kiefor, a lifelong Sox fan from Northwest Indiana with Down syndrome. Sitting in the front row with his father and sister, Kiefor exchanged a thumbs-up with Texas Rangers infielder Jake Burger during the game, and before the day ended, a security guard presented him with a bat personally signed by Burger that read “Down syndrome is cool.”
The moment capped a game that had already been an escape for the Kiefor family. According to CBS Chicago, Jacob's father Kenneth Kiefor said the family had just come through power outages and yard work after recent storms, and Jacob had hoped simply to hand Burger a business card. Instead, he walked away with a memento signed by a player he had watched compete against his hometown team.
Burger, who was selected by the White Sox in the first round of the 2017 MLB draft, played for Chicago before a 2023 trade-deadline move sent him to the Miami Marlins, and he later joined the Texas Rangers ahead of the 2025 season, according to Wikipedia. Despite the moves, Sox fans like Kiefor have kept a strong emotional tie to him, and CBS Chicago author Charlie De Mar noted that Kiefor sought Burger out specifically because of that history. Burger wears uniform number 21 to raise awareness for Down syndrome and to honor his daughter Penelope, who was born with the condition, per the same account.
A Personal Connection Behind the Jersey Number
Burger's choice of number 21 is not just symbolic shorthand — it traces directly back to his family. His daughter Penelope was born with Down syndrome in October 2024, and the following March, on World Down Syndrome Day, Burger and his wife Ashlyn officially launched the Burger Family Foundation, according to the Major League Baseball Players Association. The foundation provides direct financial aid for therapy and is developing “Lucky Ranch,” described as an inclusive sanctuary and workplace for individuals with disabilities.
The MLBPA also reported that Major League Baseball's Players Trust named Burger its Most Valuable Philanthropist for May 2026, awarding a $10,000 grant to his charity for his outreach to families affected by Down syndrome. The Burgers have credited 11-time All-Star Albert Pujols as inspiration, pointing to the Pujols Family Foundation, which Pujols established in 2005 after his own daughter Bella was born with the condition. Burger's advocacy also builds on an earlier chapter of his career: after recovering from back-to-back Achilles tendon tears in 2018 that sidelined him for two seasons, he became a prominent MLB mental health advocate, openly discussing a diagnosis of post-traumatic stress disorder and depression, per MLB.com.
An Artist Turning Adversity into Advocacy
Kiefor's own path to that ballpark moment runs through years of entrepreneurship. He founded his Saint John, Indiana-based business in 2019 after hand-making a custom doormat for his sister, and it has since grown to ship hand-crafted items featuring messages of kindness to customers in all 50 states, according to GreatNews.Life. He manages the design and production himself, with his family helping with shipping and social media.
That business, This Is Jacob LLC, drew national recognition in October 2023 when Kiefor received a $10,000 entrepreneurship grant from the National Down Syndrome Society and Voya Cares for his work promoting disability inclusion through custom apparel and hand-painted doormats, per the National Down Syndrome Society. Kiefor has said that Down syndrome is part of him for life and that he is proud to have it, and he uses his craft to spread awareness about the condition, CBS Chicago reported. His art and an arm tattoo incorporate three arrows, a design known within the disability community as “The Lucky Few” symbol, which the Homewood-Flossmoor Chronicle reports represents the three copies of the 21st chromosome that cause Down syndrome.
The Broader Picture of Down Syndrome in America
Down syndrome remains the most common chromosomal condition diagnosed in the United States, occurring in roughly 1 in every 640 live births, or about 5,700 infants each year, according to the Centers for Disease Control and Prevention. The agency's public health records also show that average life expectancy for a person born with Down syndrome in the U.S. rose from about 10 years in 1960 to roughly 47 years by 2007, a shift driven by improved surgical care for congenital heart defects and greater community integration.
That longer, more independent life is reflected in stories like Kiefor's, whose entrepreneurial success stands as evidence of the growing opportunities available to adults with Down syndrome. For his father Kenneth, the ballpark encounter needed no statistics to explain its meaning. He said Jacob told him it was the best day of his life — a description that, after the thumbs-up, the signed bat, and years of building a business rooted in messages of kindness, seemed to fit.
