The Texas Rangers player, 28, will wear number 21 for the 2025 season in honor of his daughter Penelope, who was born with Down syndrome, according to the Major Baseball League. The genetic condition, known as Trisomy 21, results in an extra copy of chromosome 21.

Jake Burger will wear No. 21 after being acquired by the Texas Rangers. The number has special significance for his family after his daughter was born in October with Down syndrome.

The new Rangers first baseman announced Friday that he will wear No. 21 to pay tribute to Penelope, who was born with Down Syndrome, and to raise awareness for the genetic condition.
