Rory McIlroy is two shots further back after the opening round at Augusta
A very strong opening round for Shane Lowry has put the Irishman two off the lead after Day 1 at the Masters.
The Offaly native finished on 4-under for the round in a tie for second after a storming front nine at Augusta and steady back-nine.
Defending champion Jordan Spieth leads the way on 6-under after a bogey-free round.
New Zealand's Danny Lee is also in a tie for second with Lowry on 4-under.
Rory McIlroy had been in a six-way tie for fourth in a pack including Sergio Garcia, Justin Rose and Ian Poulter on 3-under after 17, but dropped a shot to settle for 2-under.
World No 1 Jason Day had been vying with Lowry for second midway through the round but a triple bogey on the back nine contributed to his fall back to level par for the day.
Graeme McDowell finished level for the day, while Darren Clarke carded a 4-over round.
Two-time winner Bubba Watson starts tomorrow from 3-over, while fellow American Phil Mickelson is on level par.
