Group scores based on value in first column

I am trying to analyse a set of scores of different doubles tennis tournaments - new tournaments and new players are continuously being added and so need some dynamic way to analyse. I would like to extract sort of a ranking system based on the scores by each player and one way to do so is to analyse the scores by tournament. Basically the same players play in different tournaments and i want to be able to know who performs better than others i.e. get better total scores during a tournament.

The attached gives an example of the data i have as well as the result i would like to achieve. It does not really matter if a formula system or a pivot solution is provided as long as i achieve the result, and can add to it as new data is populated. I have been trying all sort of solutions using pivots, matches, lookups etc but no luck yet.

Any help is greatly appreciated.
