For beginners, a real life video compilation of defense ratings needed for each position

Position Proficiency doesn't matter. What matters is the rating at Arm/Error/Range/Turn DP

Third Base- 60 Arm with maybe 45 range minimum

Shortstop/2nd Base- 60 Range, Arm, Error, Turn DP, Everything 2B is slightly weaker than your Shortstop.

Extra- This is Turn DP for Shortstop/2nd Base

First Base- The guy who can't play the other infield positions but has a great bat

Centre Field- 60 Range especially at 1:45

Right Field- 60 Arm with maybe 45 range minimum

Left Field- The guy who can't play the other outfield positions but has a great bat
