Scout’s note

Rosario hits the ball as hard as almost anyone in Triple-A — an EV95 of 110.0 puts him in the 97th percentile of the 504 AAA bats we track, and the MLB value grid grades that contact at 0.38. He's a fifth-round pick out of Papaikou, Hawaii, still just 24, and the .298 average with 11 home runs in 42 games at St. Paul is the box score catching up to what the physics already said. Fifty strikeouts in that span are the trade.
