Need to predict player ranking in a particular sport given the player's data such as runs, batting average, bowling average etc. Help needed

So I have the data (several fields such as batting average, bowling average, runs per 100 balls played etc) for 101 batsmen/bowlers. I also have their ranking which has been obtained using a particular formula. That is, a score is generated for each batsman/bowler.

I need to predict this score generating formula that has been used to calculate the ranks of these players. The problem here is that I have just 101 data points (as in just 101 players, albeit with several fields).

What do I do? Should machine learning be used here?
