- Perth International, Round Two
Dufner & Van Pelt keep heat on Grillo
Leading US players Bo Van Pelt and Jason Dufner both hit 67s on day two of the Perth International to keep the pressure on leader Emiliano Grillo.
Grillo, the Argentinean world No. 516, proved his opening-round 66 was no fluke with a 67 of his own, which carried him to 11-under.
Van Pelt and Jason Scrivener are the closest pursuers at four strokes back, while Dufner is on six-under.
Grillo, searching for his maiden professional victory, has plenty at stake in Australia: he is currently 112th in the Race to Dubai, with the top 115 after next month's UBS Hong Kong Open retaining their cards for next season.
Dufner has been one of the most consistent players on the PGA Tour in 2012, winning twice, finishing fourth at the US Open and featuring in America's Ryder Cup team - and he recaptured some of that form on Friday, manoeuvring himself into a threatening position with six birdies.
Meanwhile Van Pelt, who was in contention for a Ryder Cup wildcard, peaked with an eagle at the par-five seventh. "It was a solid day," he said. "I would say the biggest difference from today from yesterday, I think I played the par-fives five-under. I think I only missed three greens, so I was driving the ball in play, and was able to take advantage of the par-fives.
"All in all, seven-under, I'm very pleased. I haven't played a tournament in a few weeks, so I like the golf course a lot. I'm just excited about the opportunity. Last time I was in Australia, I didn't get to play the weekend, so nice to get to play the weekend."
Paul Casey has endured a dismal season - once world No. 3, he is now ranked 132nd - and his 75 was another low point. He was on seven-under for the tournament through six holes of round two, before the wheels came off: a double-bogey at the second, as well as bogeys at 18 (he started on the back nine), three and five.
Former Masters champion Charl Schwartzel shot a 76 to move to four-over.
