It's been a few years, but Bedard's pitch was certainly a sweeping breaking ball. Without statcast data it could be up to interpretation as to whether it was a curve or slider, but I remember slider movement.
His fastball was mostly 91-94, which I guess for a lefty you can call plus.
Again, i wasn't taking swipes at Bedard who was very good before the injuries derailed his career, was more talking about how could Hall's stuff is. Bedard had better command though.
