Hall has proven that he has some of the best pure stuff of any lefty on the planet, but strike-throwing and durability continue to linger as major concerns. He threw a career-best 98 innings in his age-23 season across the four highest levels, primarily spending the year at Triple-A. Hall got his first big-league win and his first big-league save in 13.2 MLB innings that came over the final couple months of the season. His long-term role remains uncertain, but he's too talented and too young for the Orioles to pigeonhole him as a high-leverage reliever just yet. Hall's 36.1 K% led all Triple-A pitchers with at least 50 innings, but it came with a 14.2 BB%, which was the 14th-worst mark among that collection of pitchers. His 96-mph fastball, 87-mph slider and 85-mph changeup all have a chance to be 70-grade pitches in the majors - it's just a matter of whether he can command them well enough to start while also handling a starter's workload.
