The Red Sox signed Monmouth righthander Pat Light, their supplemental first-round selection, for $1 million.

Light is a physical 6-foot-6, 200-pounder capable of running his fastball up to 96 mph. His slider and changeup show enough potential for him to become a starter, and his velocity also could be a weapon in a late-inning relief role.

The assigned value for Light's No. 37 overall slot was $1,394,300. Boston has signed seven players in the first 10 rounds for a total of $1,011,400 under their assigned values. They may need much of that money to sign fourth-rounder Ty Buttrey.
