Jordan Spieth has Lowry and McIlroy hot on his heels

Jordan Spieth picked up right where he left off at Augusta National 12 months ago, on top of the Masters leaderboard on Thursday night, but this time with Irish duo Shane Lowry and Rory McIlroy hot on his heels, writes Simon Lewis.

Last year's wire-to-wire winner Spieth shot an opening-round 66, six under par, to lead the Masters for a fifth successive round as his mastery of Augusta National showed no signs of letting up.
