Im looking at Djokovic at -8.5 and the OU at 29.5. These together confuse me. Im assuming the spread of 8.5 means the oddsmakers predict 6-3 6-3 6-3 but with the OU at 29.5 thats 2.5 pts over the predicted total using the 6-3 6-3 6-3.
Im new to tennis, so could someone explain why someone would bet djokovic -8.5 when it seems to me that u29.5 would make more sense if they expect him to win by 8-9 pts?
