Back in spring training, rebuilding a delivery was Job One for Lucas Giolito, and the untrained eye couldn’t follow that from a distance.
The first results-based goal one could track tangibly? Throwing breaking balls for strikes. The White Sox and Giolito wanted to make hitters respect his curveball before a putaway situation, and they added a slider to his arsenal for easier strike-throwing as well.
Regarding the latter aspect, it’s back to Square One if you only saw the way he threw on Tuesday.
Over his six innings during the White Sox’ 4-1 loss to Minnesota, Brooks Baseball said Giolito threw 12 curveballs and zero sliders.
