Table Normalization Part 2

OK, to add onto previous question:

https://www.experts-exchange.com/questions/20968246/Normalizing-Tables.html

i think this design will work, but it will take some re-working of my existing application, any suggesions:

I will then post a question for SQL statements need to calculate points.

Thanx!

Teams

Players

- TeamId

- Points - Calculated

Matches
- id
- Date

MatchResults
- id
- MatchId
- TeamId
- Points - Calculated Field

Games
- Id
- MatchId
- MatchType - {Singles, Doubles}

GameResults
- Id
- GamesId
- Player - Selected from Players
- Points (not calculated)

May be:

Matches
