The final is 3rd match on court 1 following the girls singles final and an invitation doubles (best guess between 4 and 5pm start)
A win for George would be good for his morale after a pretty barren few months and a loss in the final last year. A win for Oli would help his chances of ending the year in the top 10 and gaining 3 Junior Exempts into Futures events next year (assuming they only play the US Open + one more junior event George can only realistically finish in the top 10 by winning the US Open singles).
with all due respect i would hope liam and oli wouldnt need junior exempts next year, i would expect there ranking to be good enough anway, liams already is come monday for a lot of future events
