And as per Baseball Savant over a full season in 2019, Vlad was 54th percentile in EV and 47th percentile for Hard Hit%, which reinforces what I was showing. Despite the ground balls, it is positive to see his numbers rise this year. I believe EV stabilize quickly, so it may not be a SSS. To conclude - he didn't hit the ball hard last year (compared to the rest of the league); however, he's definitely trending in the right direction this year over his first 19 games.
I was just checking guys like Soto, Tatis, Acuna and Eloy - they all hit the ball a lot harder than Vlad in their rookie years, although you can also see improvements over their first couple of years (although Eloy and Acuna haven't changed much).
