Karlsson and Singh lead US PGA

Robert Karlsson and Jeev Milka Singh made the early running at Oakland Hills with opening rounds of two-under-par 68 at the 90th US PGA Championship.

Sweden’s Karlsson, a top-10 finisher in each of the first three majors of 2008, bounced back from an opening double bogey at the par-four first hole to birdie five of the next seven holes and added another at the 11th before bogeys at the par-four 14th and 15th holes sent him back to two under for his round.
