Jordan Spieth will keep it simple to stay on course for Grand Slam

With a Masters Green Jacket in the wardrobe, it might be understandable for Jordan Spieth to kick back for the rest of the season and consider his year’s goals had been achieved.

Yet since winning at Augusta National in April, the 21-year-old world number two from Texas has mentally set his clock back to January and given himself fresh challenges starting this week at the US Open.

Spieth is determined not just to push for back-to-back major victories this week but to complete the next leg of a Grand Slam of all four majors in a year.
