Spieth 'a little tired' but determined to practice at St Andrews

World number two Jordan Spieth wasted no time in doubling his experience of the Old Course at St Andrews ahead of this week's Open Championship.

Spieth is halfway towards an unprecedented calendar grand slam after winning the Masters in April and the US Open last month, but only arrived at the Home of Golf on Monday afternoon after beating Tom Gillis in a play-off for the John Deere Classic in Illinois on Sunday.
