The biggest keys for Severino will be commanding his fastball and keeping his pitches down in the zone. His heater averaged 96.1 mph last season, according to FanGraphs, but opposing batters hit .299/.383/.544 against it. His secondary pitches — the slider and changeup — will also need to be more consistent, as he struggled mightily the second time (16.0 IP, 35 H, 12.38 ERA) and third time (8.2 IP, 13 H, 13.50 ERA) through the order.
