The first thing to know is that not all professional baseball scouts are the same. They have different priorities for assessing players, along with different backgrounds and expertise.

One scout who's been doing this a while is Carlos Gomez.

Not only does he have experience pitching professionally, but he's been working within baseball for over a decade. In that time he's learned to assess the qualities of elite players.

Most notably he worked as the Director of International Scouting for the Los Angels Angles and has some keen insights on Latin American baseball prospects.
