Ethan Holliday, the top prospect of the Colorado Rockies, will undergo left foot surgery and be out for the season, MLB.com reported.
The 19-year-old shortstop, who was the No. 4 overall pick in the 2025 MLB Draft, suffered a stress fracture and was put on the injured list by Single-A Fresno. He has not played since May 20.
It is unclear when and how the injury occurred, per the report. The Rockies have yet to announce the surgery.
Holliday, drafted out of Oklahoma’s Stillwater High School, signed with the Rockies for a $9 million bonus — the largest bonus ever for a high schooler. He started his pro career at Fresno after the draft and returned there this spring.
He will end this season with a .262 batting average with nine home runs and 32 RBIs in 33 games. Before the injury, he was enjoying a solid May, hitting .295 with six homers, four doubles and a triple in 15 games.
MLB Pipeline lists him as the No. 17 overall prospect with an estimated arrival in the major leagues in 2029. At 6-foot-2, 210 pounds, Holliday is expected to move to third base down the line.
His older brother, Jackson Holliday, was the No. 1 pick of the 2022 MLB Draft by the Baltimore Orioles. Also an infielder, Jackson recently made his season debut, after being sidelined with a fractured hamate bone sustained in batting practice prior to the start of spring training in February.
In 10 games in 2026, he is hitting .259 with two homers and five RBIs.
Their father, Matt Holliday, was a seven-time All-Star who played for four teams but is best known for his long stays with the Rockies and St. Louis Cardinals.
