McIlroy stars as Kaymer struggles
It was a day to remember for Rory McIlroy in The Masters - and one to forget for Padraig Harrington and world number one Martin Kaymer.
While they shot 77 and 78 respectively - Harrington nearly pulled out with neck trouble - McIlroy charged into a two-stroke lead over Korean YE Yang and big-hitting Spaniard Alvaro Quiros with a dazzling seven-under par-65.
Although Quiros still had five holes to play and the opportunity to take over at the top, the 21-year-old Northern Irishman's round brought back memories of his major record-equalling first round 63 in The Open at St Andrews last July.
But that is where he hopes the comparisons end - as McIlroy followed that round with an 80.
Tiger Woods, meanwhile, started with a 71, while defending champion and favourite Phil Mickelson, in the second last group of the day, was two under after escaping from the bushes with a par at the long 13th and from the trees with a birdie at the next.
After saving par from the fairway bunker at the first he birdied the next three from two, five and 20 feet, making a 10-footer on the ninth to turn in 32.
The 505-yard 11th is probably Augusta's toughest hole, but he struck a five-iron to eight feet for his fifth birdie and, after three-putting the long 13th for par, picked up further shots at the next two.
First he holed from 10 feet again and then he was on in two at the par five and two-putted.
Yang, who became Asia's first major champion by beating Woods head-to-head at the 2009 US PGA, moved alongside McIlroy with a two at the short 16th, but bogeyed the last two.
