Heineken Classic

England's Paul Casey stretched his advantage on day two in Melbourne to two shots as tournament favourite Ernie Els slumped out of contention.

Casey had started the day a stroke clear of the chasing pack but pulled further clear with a five-under-par 67.

He is two shots ahead of fellow Englishman David Lynn, with still half of the field yet to finish.

Els, in stark contrast to the English duo, managed par for the round to leave him 10 shots off the pace.

Casey got his round off to the perfect start with birdies on the opening two holes before managing an eagle on the ninth.

A birdie 10th was cancelled out by a drop shot on the very next hole but another birdie pulled him two clear with 36 holes left to play.

"It was tougher than yesterday. There was a very cold wind and the ball wasn't going as far," said Casey.

Els, the form man in world golf this season after winning two USPGA events, failed to continue that in the sunny conditions.

Like Casey, he opened his round with successive birdies but, in an inconsistent display, bogeyed the next two.

A missed putt from five feet on the 14th resulted in a double bogey before two birdies late on restored some pride for the South African.

Afterwards he said: "This is my fourth week (in a row), and it's quite a way to travel."

Bob Hope Classic

Jay Haas shot a stunning 61 to move into a one shot lead in La Quinta, California.

Haas, who is old enough to play on the Seniors Champions Tour next season, rolled in a three-foot putt on the 18th hole for his third consecutive birdie and to move clear of Harrison Frazar in second place.

The 49-year-old Haas chipped in from 18 feet to open his round with a birdie.

He then carded three more successive birdies before finally ending the turn on 31. His efforts were even more impressive on the back nine, as he ended with another straight birdies.

Haas' round of 61 was matched by Pat Perez, who lies two strokes back in third place.

Perez shares third with joint overnight leader Stephen Ames who could only manage a 67, and Joe Durant, who added a 63 to his previous round of 67.

Despite the sunny, windless conditions, David Duval slumped to a staggering 78 after an impressive opening round of 65.

The former Open champion struggled from the outset of the round, with a string of wayward shots.

Northern Ireland's Graeme McDowell shot a second successive 69 to lie 10 shots behind the leader.
