Bradley praises Kaymer

At most other US Open’s Keegan Bradley would be right in the mix after a second 69 put him on two-under at the halfway stage, but at Pinehurst No 2 that sees him eight shots behind runaway leader and playing partner Martin Kaymer.

Instead of questions about how he himself could challenge for a second major, Bradley was being quizzed about Kaymer's incredible 65-65 start to the US Open - having had a ringside seat in the same group for two days.

"He's playing so good, it's fun to watch," said 2011 USPGA champion Bradley. "I played well as well, but it was fun watching him hit every fairway, every green and make every putt, it was pretty awesome.

"He's dialled in. He's as dialled in as I've seen."

Kaymer, also a USPGA champion, eclipsed Rory McIlroy's record of the lowest 36-hole total in US Open history with his 130 putting him on ten-under as he made a mockery of the course that was proving so tough for the rest of the field.

Finding the short stuff helps, and Kaymer has been relentless at that, with 12 of 14 fairways found off the tee and 15 greens in regulation by the German as he took his game to a different level.

"He's just hitting the ball in the fairway on every hole and that's how you score," said Bradley.

"If you hit the ball in the fairway, you can attack a lot of these pins and these greens. When you get off the fairway into the waste area, that's when it can get dicey.

"He's just very steady. He doesn't seem to get too up and too down. That's a pretty good combination for the US Open."

Despite Kaymer having a huge lead, Bradley is not about to go chasing too hard at the weekend, as that can quickly be your undoing at the US Open.

"The course is too hard. You just got to stick with the game plan. There's no place to force anything. It's just similar to Augusta in that there's a double on every hole if you're not careful, so stick to the game plan.

"We've got to see what happens tomorrow, but the back nine on Sunday is where it all kind of happens. Steady golf out here is going to be tough. You need to go out there tomorrow, make a bunch of pars and you never know what's going to happen."
