The Colorado Rockies have signed first-round draft pick Ethan Holliday to a record-setting $9 million bonus, surpassing slot value and marking the largest signing bonus ever given to a high school player, per MLB.com.

Holliday, the No. 4 overall pick out of Stillwater High School in Oklahoma, is the youngest member of baseball’s most prominent family. The son of seven-time MLB All-Star Matt Holliday and younger brother of Orioles shortstop Jackson Holliday, Ethan was MLB Pipeline’s top-rated prospect and a projected Oklahoma State signee.

The left-handed hitting shortstop boasts advanced plate discipline, big-league strength, and impact power, with many scouts expecting a future move to third base. His $9 million deal ranks as the fourth-largest bonus in MLB Draft history and leaves Colorado with just over $6 million to sign its remaining picks.
