Areas of Improvement
Defensively, Rosario’s footwork could use more consistency. How he gets to ground balls was an issue especially early on and that put him in more compromising positions. Once that happens, we should see a significant jump into the upper echelon of defensive shortstops for the now 22-year old Rosario. In short, he looks to have a bright future in the field.
The larger question is will he hit consistently enough over time? That directly ties into how much he can improve his plate discipline. That’s the one thing preventing Rosario from being a potential lead-off hitter at the moment.
He has the speed to hit lead-off and is currently the quickest and most aggressive baserunner on the team. Generally, you don’t want someone who is more prone to strikeouts in that slot. Rosario may never have Joey Votto level plate discipline, but even some improvement will lead to a more prominent role in this Mets offense moving forward.
