PITTSFORD, N.Y. -- Brooks Koepka says he thrives in majors because they're the toughest tests. The PGA Championship was every bit of that on a rainy Saturday at Oak Hill, and so was Koepka.
Koepka was at his best even during occasional downpours, and he surged into the 54-hole lead for the second straight major. He had a 4-under 66 -- the low round at Oak Hill for the second straight day -- and led by one shot over Viktor Hovland and Corey Conners.
Now he has to finish it off.
