Dustin Johnson reveals world number one ambitions
A fortnight after claiming his first major title in the US Open at Oakmont, Johnson joined Tiger Woods as the only players to win three different World Golf Championship events, with victory in the Bridgestone Invitational.
The 32-year-old carded back-to-back rounds of 66 over the weekend in Akron to take advantage of a late collapse by world number one Jason Day, who bogeyed the 15th and double-bogeyed the 16th in the final round at Firestone Country Club.
