Sandoval made his big-league debut in early August and held down a rotation spot for the rest of the season despite largely mediocre results. His 24.9 K% was strong, but it came with a poor 11.2 BB%. A 21.4% HR/FB rate also held him back and indicates potential positive regression going forward, while his 4.02 xFIP paints a fairly optimistic picture of what he's been able to do thus far. His fastball averaged 93 mph (fine for a southpaw) and he pairs it with a swing-and-miss changeup, a high-spin curveball and fourth-pitch slider. Even with the unconvincing start to his career, he enters 2020 poised to either break camp in the rotation or serve as the next man up in the case of an injury, and injuries typically hit this rotation harder than most. His command issues make him a WHIP liability, but he should be a solid source of strikeouts if he gets the innings. Read Past Outlooks
