I am unaware of the Fielding Chart containing a homerun. There are hit + error results that can bring the batter home but those are scored as hit + error.
In the Windows game, there is an odd play result where a fielder (usually rated 4 or worse) misplays a ball which results in an inside the park homerun. So perhaps that is what resulted.
Looking at the Super Advanced X-Chart, there is a 0.28% chance for an inside the park homer with an outfielder range of 4 and a 0.14% chance with an outfielder range of 5.
Highly likely that it is the 88 or 89 card but not impossible that it could be the 90 card (look at the fielder's rating)
