One stat? No. But here are the three most important things in a hitting prospect for me:
Age - the younger for the level, the better
A 22-year-old in AAA with a .750 OPS is likely a better prospect than a 26-year-old with an .850 OPS in the same league.
BB to K ratio - the more walks and less strikeouts, the better
Few walks and many strikeouts is a big red flag and indicates the player will likely struggle against more advanced pitching.
Isolated power - the higher, the better
Good contact and plate discipline won't get you very far if you can't drive the ball.
Also, it's important to note whether the player's numbers are inflated by the Pacific Coast League since it's such a notorious hitter's league.
