What is the Total Games - 3rd Set Over/Under 6.5 market?
                  A 
wager on whether the 
total number of games in the third set will be 
over or 
under 6.5. A 
bet on 
over 6.5 games would typically be a heavy 
favorite, whereas a 
bet on 
under 6.5 games would mean the exact score needs to be 
6-0 to either 
player and hence a big 
underdog.
