The latest piece by Fegan about the pitching staff, technology, Cooper and more importantly Giolito was fantastic.
Cease changed his delivery and looks a lot like Giolito; as he spent all off-season working with Giolito to fix his spin and balance issues. His grip issues and etc. His glove being far from his body through him off balance.
Lopez, who had turned down Giolito's offer last off-season (to which Giolito said he felt he'd never come around) and worked out in DR, took Lucas up on the offer this off-season. He also went to learn about maximizing his spin, command and etc with modern new-age tech that Lopez wasn't a big believer in prior.
Giolito also made changes; to his slider grip, and he worked all off-season to find that old 12/6 hammer's release point to throw it for strikes.
And Carlos Rodon has been using all the new Sox tech to learn how to use his lower body more (he always stood so tall) to tech stress off his legs.
This is obviously a spring training fluff piece in a way, but players believe when other players have huge turnarounds like Giolito. They bought in, and who knows how well it may benefit the team going forward.
