Jackson Holliday fun facts

• When Holliday makes his MLB debut, he will be the second-youngest player in the major leagues. The other two players rounding out MLB's youngest three, coincidentally, are also named Jackson: the Brewers' Jackson Chourio and the San Diego Padres' Jackson Merrill.
• ESPN MLB reporter Buster Olney (kind of) predicted this moment back in 2013, when Holliday was nine years old. "Matt Holliday's son: Future All-Star," he wrote on X (then-Twitter) 11 years ago.

Notably, Matt Holliday has another son, Ethan, who was six years old at the time and may be a top pick in the 2025 MLB Draft.
