Both are different pitchers as Bell has much more velocity, while Hall racks up strikeouts with his curveball.
Still, both could find success in shorter stints.
In terms of pitch count, when Bell was working with 25 pitches or less in a game, he held opposing batters to a .238 batting average, a .306 on-base percentage, a .361 slugging percentage and a .667 OPS in 134 plate appearances.
When you add that with the fact that the southpaw’s fastball could play up from its average velocity of 93.4 (per FanGraphs), there’s plenty of potential in the bullpen for Bell.
Hall ended the season as the 27th-best prospect according to MLB.com’s Pipeline.
The same publication wrote the following about the Double-A Erie pitcher:
"“Upon first glance, hitters likely think Hall is the kind of pitcher they will light up, largely because of a below-average fastball that doesn’t even scrape 90 mph. What he does have is an outstanding curve that he will throw at any time. He can really spin it and will find continued success if he keeps commanding it well.”"
Hall earned a promotion to Erie for the first time this season, and found plenty of success, with 38 strikeouts and a 3.09 ERA in six starts spanning 35 innings.
Like Bell, he could find success in a shorter relief role.
