PGA overnight: McIlroy in awe at Tiger's 'monumental' mental strength

American Will Zalatoris fired a 65 to claim the 36-hole lead at the PGA, a shot ahead of Chile’s Mito Pereira with Bubba Watson lurking

PAIN GAME: Tiger Woods on the 12th during the second round of the PGA Championship at Southern Hills

TULSA, Oklahoma – Bubba Watson was just trying to make the cut. He ended up getting a lot closer to the lead instead, tying the PGA Championship record with a 63 despite two bogeys and a near-miss on the last that would have been his 10th birdie of the day.

Watson made the most of a relatively calm afternoon at Southern Hills, making nine birdies to climb into solo fourth place at 5-under overall. But he was hardly alone in an afternoon scoring blitz after the winds died down and the course became somewhat defenceless.
