5 most underrated prospects dealt at the MLB trade deadline
4. RHP Nick Robertson: Boston Red Sox (Dodgers)
Boston’s bullpen is among the Top 5 as far as WAR goes in the league according to FanGraphs(4.2) and they get a quality arm in Robertson, who will report to Triple-A Worcester.
Robertson features a fastball that can touch 98MPH with a slider and changeup. He posted a FIP of 2.94 with a K per 9 of 13.34 at Oklahoma City, holding batters to a .184 batting average. If he can throw his slider with more consistency, Boston could have a potential closer option in the future. His change has good downward fade on righties.
