Here are some notes that I collected on this topic:

Game logs include specific locations for hit balls, according to the convention used by Retrosheet. You can find out more about this convention at Retrosheet Hit Location Diagram.

Notes on some differences in the way OOTP shows ball hit locations:

Centerfield can be further described as left of center (not left-center, which is 78) or right of center (not right-center, which is 89) by inserting "L" or "R" directly after the "8", as follows: 8LXD is deep and slightly to the left of dead center and 8RXD is deep and slightly to the right of dead center. Similarly, "8LM" and "8RM" are the same but to medium centerfield.

With other field locations, "L" generally means "close to the foul line."

"15S" and "13S" are both bunts or squibs back to the pitcher, third base and first base side respectively.

"2L" is a fair popup to the catcher position, near the foul line or in front of the plate. "2LF" is a foul popup to the catcher position. "2R" is a fair bunt or a squib usually fielded by the catcher.

The game appends "F" to a fly ball caught in foul territory. For example, "7LSF" is a fly caught by the leftfielder on foul ground.

Note that these are positions, not players. For example, a pitcher could catch a foul popup near the plate. This play would then be scored F1 2LF.
