[Number4]

The 1B is a corner outfielder, the RF could play center, the CF is a 3rd baseman and the 3rd baseman is a potential gold glove first baseman.

Instead, the AI plays 3 unrated/low rated players who aren't able or really able to play that position (the 3rd baseman in center has a outfield range of 45/100, the 1st baseman at third an arm of 43/100, the RF at first could develop first base, as everyone, but there is no need to.

Playing 3b at center, a first baseman at third and a outfielder at first makes no sense even if there wasn't a center field capable outfielder at right, you should at least play 2 out of 3 at their best positions and the corner outfielder is the best choice for CF out of the 3.
