I would not consider that the worst as he's a pitcher. I'd consider that to be about what to expect. Comparing Bukauskas AFL (in a couple of games that had Trackman) stuff versus Severino's 2017-2018 stuff using Brooks Baseball... Severino's fastball is about 2 mph faster with about 2 inches more "rise". Sliders are about the same with Severino getting about 2 inches more sweep with Bukauskas getting about 0.5 more dive. Bukauskas throws his changeup about 2 mph faster (but with still a good 5 mph separation with FB), gets about 2 more inches of vertical separation despite being faster (or about 4 more inches of drop) and 3 more inches in tailing action. Granted, this is only based on 24 change-ups thrown in the AFL and 3 shown in Pitching Ninja Tweets, but for a fastball/slider guy..it looks like his best pitch from a velocity/movement standpoint is by far the change-up. This does not look at control/command, consistency, how well he switches up pitches, and health.
I love these overlays. They really show why batters that batters have to decide early whether a pitch is a breaking ball or a fastball. Decide wrong and you are taking a fastball over the plate or swinging at a breaking ball out of the zone.
Oakland camera shows off the vertical movement well (mostly gravity), but mutes the perceived horizontal movement.
Small sample size but I didn't see many backdoor sliders to lefties or front-door sliders to righties. I wonder if Mchugh doesn't feel as comfortable throwing to that side of the plate or that's just where Chirinos is setting up.
McHugh does throw front door sliders to RHBs usually. Maybe not last night, but he gets a lot of called strikes generally on them. I don't think he uses backdoor sliders to lefties often. He uses his curveball and fastball more against lefties.
I guess I meant in the sense that he's not often catching the inside plate on righties. Seems like most of his sliders to righties land middle-middle, outside plate or outside.
