US potential in US Open Betting finals at SBG Global. It has been some time since a Grand Slam tournament was swept by players of the host country, but it can be different in this year’s US Open betting. US Open odds makers aren’t necessarily guaranteeing such a rare feat, but with the current success of the Williams sisters and the past success of Andy Roddick in the US Open betting, an American sweep is not all that far fetched in this year’s US Open odds competition. The Williams women have a much better chance than Roddick in the US Open but this could be the US player’s year to shine.
