Scout’s note

Rosario, a 2020 fifth-round pick out of Papaikou, HI, has 9 homers and a .927 OPS in 35 games for the St. Paul Saints this year. No MLB debut yet. The exit velocity grades as MLB-ready contact; pre-consensus means we said it before the market did.

Current signals

The read: Rosario's EV95 of 110.1 sits in the 97th percentile of the 486 AAA bats we track (median 104.9), and on the MLB value grid his contact grades at 0.39. The tools are ahead of the market — that's what pre-consensus means.
