By Ben Everill CHERRY HILLS VILLAGE, Colorado (Reuters) - Spain’s Sergio Garcia fired an impressive six-under-par 64 to take the halfway lead at the BMW Championship on Friday, with world number one Rory McIlroy only two off the pace after another 67. Garcia holed out for an eagle from 126 yards, hit five birdies and a lone bogey to move to eight-under par for the tournament, leaving him one clear of American Ryan Palmer in the Tour's penultimate playoff event. Palmer holds outright second at seven-under after matching Garcia’s 64, while McIlroy's second successive 67 put him tied third with American Billy Horschel (66) at six-under. Garcia, looking for his first win on the PGA Tour this term, started relatively slowly with just one birdie in the opening six holes before he kick-started his round by holing out from the fairway for eagle on the par four seventh.
