Walker grabs PGA lead as McIlroy, Mickelson struggle

Jimmy Walker, who missed the cut in three of his past four major starts, fired a five-under par 65 Thursday to grab a one-shot lead in the first round of the PGA Championship. The 37-year-old American, whose best major showing in 17 starts was a share of seventh at the 2014 PGA, owned a one-stroke lead over Argentina's Emiliano Grillo on a day when stars Rory McIlroy and Phil Mickelson struggled at par-70 Baltusrol. "All in all it was a great day," Walker said.
