What happened: The Washington Nationals have agreed to terms with fourth-round draft pick Cooper Harris on a $1.5 million signing bonus. The Texas high school right-hander had previously been committed to play for the Texas Longhorns. The deal easily surpasses the $740,500 slot value assigned to the 106th overall selection.

Why it matters: By aggressively going over slot, Washington secures a highly projectable 6-foot-3 pitcher with a four-pitch mix. The investment continues the club's strategy of prioritizing high-upside prep arms to rebuild their system. The move was enabled after the team signed first-rounder Chris Hacopian to a $5.7 million under-slot agreement.

What to watch: Harris will report to the Nationals' development complex to begin his professional pitching program.
