After giving up 33 rounds under par yesterday, Augusta National hit back with the aid of some wind and rain on the second day of the 77th Masters Tournament.
Overnight joint leader Sergio Garcia was among those to struggle as only four players stood under par for the day after almost three hours of play.
Garcia shared the lead with Australian Marc Leishman after an opening 66, equalling his lowest round at Augusta.
It was the first time Garcia had led a major since the 2007 Open Championship, when he led outright after each of the first three rounds but eventually lost out in a play-off to Padraig Harrington at Carnoustie.
The 33 year old finished second in the US PGA Championship as a 19 year old back in 1999 and has had 15 top-ten finishes in 57 Major appearances.
Garcia found himself second after three holes of his second round, making pars on the first two holes before making a mess of the short par four third.
After driving into a fairway bunker and coming up short of the green with his approach, Garcia's pitch ran over the back of the green, from where he putted up ten feet short of the flag.
He did at least hole that putt to drop only one shot, leaving Leishman - who was among the later starters - alone at the top of the leaderboard.
Garcia was not alone in finding life difficult however, with Dustin Johnson suffering a shank on the par five second which sent his second shot all the way across the fairway and on to a spectator walkway crossing the adjacent third.
Johnson, third overnight after a 67, saved par there but had bogeyed the first and dropped another on the third to lie three under par alongside Spain's Gonzalo Fernandez-Castaño, who had started with a birdie on the first but dropped shots on the third and seventh.
Meanwhile, Chinese schoolboy Guan Tian-lang, at 14 the youngest competitor in Masters Tournament history, was one over for his round after six holes and two over for the tournament as he continued his remarkable performance.
Asked if he could win the event after his opening 73, Guan said: "I think probably not this year but I think I can win it in the future. I want to win a Major and hopefully I can win the four Majors in one year."
