McIlroy is back in the race after shocking triple bogey looked to have ruined chances
Rory McIlroy had to show impressive powers of recovery after a dreadful start to his opening round at the Deutsche bank Championship.
The Holywood star ended the first round on level par, six shots behind early leaders James Hahn and Ryan Moore but it could have been much, much worse.
McIlroy had dropped a shot at his second hole, but at his third - the 12th on the course - he hit a terrible triple bogey seven which placed him on four over par and already looking like he was out of contention in the second tournament in the FedEx Cup series.
Given his recent putting woes, some may have felt McIlroy would continue to falter but rather than fall back further, he rallied to make two birdies in the remainder of his front nine before gaining another two shots on his back nine.
At level par, the four time major champion will believe he has played himself back into contention for a tournament he is keen to win.
Americans Hahn and Moore both carded six under par rounds of 65, one shot ahead of England's Paul Casey.
Olympic champion Justin Rose was three under after his first round, as was Open champion Henrik Stenson, two players continuing their fine form, much to the relief of European Ryder Cup captain Darren Clarke who will need both firing when they take on the Americans.
Clarke will also look to Spanish star Sergio Garcia for inspiration.
Like Rose and Stenson, Garcia was one of a number of players content with a round of three under to open his bid for glory at the Deutsche Bank Championship.
Jordan Spieth, who will be a key figure in the American team, hit the same score.
McIlroy's compatriot Graeme McDowell, not one of Clarke's wild card picks for the Ryder Cup, was three over after his first round.
Meanwhile, Jason Day's wife has been released from hospital after being involved in a car accident, the world number one has announced in a statement.
Day, who shot a one under par round, was informed of the incident upon completion of the his first round at the Deutsche Bank Championship in Boston.
The Australian's two children were also in the car but were not taken to hospital and he is to continue playing in the US PGA Tour's second FedEx Cup play-off event.
"After the completion of my round today, I was informed my wife Ellie our children Dash and Lucy and friend Katie were involved in a traffic incident near our RV," said Day in a statement released on his Twitter account.
"Their car was hit by a bus and Ellie was taken to the hospital for precautionary measures.
"Thankfully everyone is now resting comfortably and Ellie has been released.
"They will be monitored in the coming days.
"We want to thank the emergency services and hospital personnel for their assistance," he added.
