Hit	50	His swing tends to get a bit long, leading to inconsistent contact and an elevated swing-and-miss rate for the speedy outfielder. He's recently demonstrated an improved ability to stay shorter through the hitting-zone, keeping his hands inside the baseball and utilizing the middle/opposite field more often. A higher rate of balls-in-play would allow Rosario to better utilize his speed from the left side of the batter's box and increase his hit totals.
Power	40	A level swing and a fondness for old-fashioned base hits will limit Rosario's traditional power, although he will occasionally turn on the inside pitch (3 HR in 413 AB). In general, he's looking to spray the yard with hard contact and utilize his running ability to gather the extra-bases.
Baserunning/Speed	60	Rosario glides over the basepaths with an effortless stride, capable of stretching a single into a double, and going 1st-to-3rd with ease on base-hits. He's yet to master the art of basestealing (10 SB/4 CS in 2019), although his high on-base capabilities and natural quickness suggest 25+ stolen bases per season are easily within his grasp.
Glove	70	Rosario ranges far and wide to settle under baseballs, utilizing adept reads off the bat, efficient routes, and a closing speed suitable for the Serengeti. His natural athleticism and progressing instincts for the position equate to a plus-defending center fielder.
Arm	55	The left-hander flashes a plus-throwing arm and an affinity for the assist, occasionally baiting runners into his trap with a false hesitation. Good positioning and a quick release are sometimes thwarted by his three-quarter arm slot, which can lead to an arm-side tail and ensuing inaccuracy.

Already a plus-defending outfielder, Rosario's ultimate ceiling will rely on his continued offensive development. His floor may be as a defensive fourth outfielder off the bench, but he's flashed enough offensive potential to be an everyday contributor, possibly atop the lineup. There's still plenty of upside and projection in the talented 19-year-old, who could develop into a prototypical plus-defending/leadoff-hitting centerfielder.
