Grabmann works east to west with his sinker/slider mix, he'll throw the occasional changeup with a tumbling action. But he predominately pitches off his low-90s sinker that has a tough, running action from his low release. When he elevates with it, it can have some carry due to the release. Like his slider, it's a platoon neutral pitch he can land in any count. Neither of them have the velo or shape to be a better than average big league pitch but he could be an interesting one inning look. The upside isn't high, but the sinker shape is alright and with velo gains it's a decent profile.
