05/28/2019 - 2019 Under Armour Showcase: Baseball Factory's National South Marquis is an athletic RHP who is a top prospect on the mound. Delivery is sound / repeatable as he shows good tempo through a strong balance point, allowing his arm action to work quick and free to the plate. Fastball shows a range of 88-91 mph with arm side run. Breaking ball displays 11/5 shape with late break. He maintains arm speed on his changeup and shows a plus feel for pitch with arm side run. Command / control is outstanding as he locates well to both sides of the plate. Marquis has a tremendous upside on the mound with the makings of a solid draft pick in 2020.
