Rory McIlroy vowed not to get ahead of himself as he headed into the second round of the US PGA Championship in pole position to end his major drought.
Since winning the last of his four majors in the 2014 US PGA, McIlroy had been a combined 35 over par in the first round of golf’s four biggest tournaments, his most recent effort being a one-over-par 73 in April’s Masters.
