Yup. I'm watching Zack Littell right now and he's throwing like 50% sliders, a bunch of them at 85-87 mph. He hasn't been a starter since 2018, but the Rays are going to have him throwing a few dozen high velo sliders a game. It will work until his arm explodes in June, but they won't care because they have nothing invested in him and can just move on to the next guy up.
