Who is Ethan Holliday? What to know of top-ranked high school prospect in 2025 MLB Draft

Top high school prospect Ethan Holliday comes from quite the baseball family, and he's likely to follow in his brother's footsteps as a top pick in the upcoming MLB draft.
Holliday, regarded as the top high school prospect in 2025, is a surefire top five pick, but whether that's No. 1 overall to the Washington Nationals, No. 4 to the Colorado Rockies, or anywhere in between, is to be determined.
The left-handed slugger attends Stillwater High School, where he was named the Gatorade Player of the Year in Oklahoma after hitting 19 home runs and 61 RBIs with a .611 batting average as a senior. He was also named Baseball America's High School Player of the Year.
If Holliday pans out anywhere close to his brother, Baltimore Orioles second baseman Jackson Holliday, he'll likely be on a fast-track to MLB given his obvious talent despite his young age.

MLB Pipeline says this about Holliday: "Holliday may have the most usable left-handed power in the Draft and he generates it with little effort. Still adding to his 6-foot-4 frame, he already has plenty of strength and an easy left-handed swing with plenty of bat speed and leverage. ... he should develop into at least an average hitter with 35-homer pop and plenty of walks."
