Jordan Spieth: Staying ahead of Rory in world rankings No.1 priority

World number one Jordan Spieth’s stellar year would be capped with victory in the multi-million dollar FedEx Cup but he admits his main focus is ensuring he stays ahead of Rory McIlroy.

The 22-year-old American won the first two majors of the year, contended in the other two, and has recorded two other victories.

That puts him well ahead of the field as the season enters its final four events, which culminate with the Tour Championship at East Lake with a $10 million (€13.6m) prize on offer to the eventual champion.
