If this is Jordan Spieth without yet being able to swing a club properly then the rest of the field had better watch out. The boy wonder is back. An already intriguing Masters leaderboard was lent a whole new dimension by the return of the 2015 champion to the sharp end of proceedings. Spieth’s second round 68, which has left the Texan at five-under for the tournament in a share of fourth place, two off the lead of England’s Justin Rose, was one thing. The 27-year-old was solid tee to green, hitting 11 of 14 fairways and 14 of 18 greens in regulation.
